ABSTRACTMedium- and long-chain fatty acids are present in organisms in esterified forms that serve as cell membrane constituents and storage compounds. A large number of organisms are known to accumulate lipophilic materials as a source of energy and carbon. We found a bacterium, designated GK12, that intrinsically accumulates free fatty acids (FFAs) as intracellular droplets without exhibiting cytotoxicity. GK12 is an obligatory anaerobic, mesophilic lactic acid bacterium that was isolated from a methanogenic reactor. Phylogenetic analysis based on 16S rRNA gene sequences showed that GK12 is affiliated with the familyErysipelotrichaceaein the phylumFirmicutesbut is distantly related to type species in this family (less than 92% similarity in 16S rRNA gene sequence). Saturated fatty acids with carbon chain lengths of 14, 16, 18, and 20 were produced from glucose under stress conditions, including higher-than-optimum temperatures and the presence of organic solvents that affect cell membrane integrity. FFAs were produced at levels corresponding to up to 25% (wt/wt) of the dry cell mass. Our data suggest that FFA accumulation is a result of an imbalance between excess membrane fatty acid biosynthesis due to homeoviscous adaptation and limited β-oxidation activity due to anaerobic growth involving lactic acid fermentation. FFA droplets were not further utilized as an energy and carbon source, even under conditions of starvation. A naturally occurring bacterium that accumulates significant amounts of long-chain FFAs with noncytotoxicity would provide useful strategies for microbial biodiesel production.

Two lactic acid-producing, Gram-stain-positive rods were isolated from a microbial mat actively growing in the littoral zone of an Antarctic lake (Forlidas Pond) in the Pensacola mountains and studied using a polyphasic taxonomic approach. The isolates were examined by phylogenetic analysis of the 16S rRNA gene, multilocus sequence analysis of pheS, rpoA and atpA, and biochemical and genotypic characteristics. One strain, designated LMG 26641, belonged to Carnobacterium alterfunditum and the other strain, designated LMG 26642T, could be assigned to a novel species, with Carnobacterium funditum DSM 5970T as its closest phylogenetic neighbour (99.2 % 16S rRNA gene sequence similarity). Carnobacterium iners sp. nov. could be distinguished biochemically from other members of the genus Carnobacterium by the lack of acid production from carbohydrates. DNA–DNA relatedness confirmed that strain LMG 26642T represented a novel species, for which we propose the name Carnobacterium iners sp. nov. (type strain is LMG 26642T  = CCUG 62000T).

Emended Description

Strains 1-1NT and GYSZ_1T were isolated from marine sediments collected from the coast of Xiamen, PR China. Cells of the two strains were Gram-stain-negative, rod-shaped or slightly curved. Strain 1-1NT was non-motile, whereas strain GYSZ_1T was motile by means of one polar flagellum. The temperature, pH and salinity concentration ranges for growth of 1-1NT were 10–45 °C (optimum 30 °C), pH 5.5–8.0 (optimum 7.0) and 0–90 g l−1 NaCl (optimum 50 g l−1), while the growth of GYSZ_1T occurred at 4–45 °C (optimum 33 °C), pH 5.0–8.5 (optimum 6.5) and 5–90 g l−1 NaCl (optimum 20 g l−1). The two novel isolates were obligate chemolithoautotrophs capable of growth using hydrogen, thiosulfate, sulfide or elemental sulfur as the sole energy source, and nitrate, elemental sulfur or molecular oxygen as an electron acceptor. The major fatty acids of 1-1NT were C16 : 1ω7c, C16 : 0, C18 : 1ω7c and C18 : 0, while the predominant fatty acids of strain GYSZ_1T were C16 : 1ω7c, C16 : 0, C18 : 1ω7c and C14 : 0 3-OH. The DNA G+C contents of 1-1NT and GYSZ_1T were 34.5 mol% and 33.2 mol%, respectively. Phylogenetic analysis based on 16S rRNA gene sequences indicated that 1-1NT and GYSZ_1T represented members of the genus Sulfurimonas , with the highest sequence similarities to Sulfurimonas crateris SN118T (97.4 %) and Sulfurimonas denitrificans DSM 1251T (94.7 %), respectively. However, 1-1NT and GYSZ_1T shared 95.5 % similarity of 16S rRNA gene sequences, representing different species of the genus Sulfurimonas . On the basis of the physiological properties and the results of phylogenetic analyses, including average nucleotide identity and in silico DNA–DNA hybridization values, strains 1-1NT and GYSZ_1T represent two novel species within the genus Sulfurimonas , for which the names Sulfurimonas xiamenensis sp. nov. and Sulfurimonas lithotrophica sp. nov. are proposed, with the type strains 1-1NT (=MCCC 1A14514T=KCTC 15851T) and GYSZ_1T (=MCCC 1A14739T=KCTC 15853T), respectively. Our results also justify an emended description of the genus Sulfurimonas .

A Gram-stain-negative, non-spore-forming, aerobic, curved rod-shaped bacterium, designed strain R142T, was isolated from a coralline algae Tricleocarpa sp. in the Beibu Gulf, China. Optimal growth occurred with 0–0.5 % (w/v) NaCl, at 25 °C and at pH 8. Global alignment based on 16S rRNA gene sequences indicated that strain R142T shared 93.8 % similarity with its closest type strain, Pseudomaricurvus alkylphenolicus KU14GT. Phylogenetic analyses showed that strain R142T forms a distinct branch alongside Maricurvus nonylphenolicus KU41ET, Pseudoteredinibacter isoporae SW-11T, Pseudomaricurvus alkylphenolicus KU14GT, Pseudomaricurvus alcaniphilus MEBiC06469T and Aestuariicella hydrocarbonica SM-6T. The major polar lipids of strain R142T were phosphatidylethanolamine and phosphatidylglycerol. The primary cellular fatty acids were C16 : 0, C16 : 1ω7c, C18 : 1ω7c, C18 : 0 and C14 : 0. The genome DNA G+C ratio was 56.4 mol%. The only detected respiratory quinone was ubiquinone 8. The low 16S rRNA gene sequence similarity and differences in cellular fatty acids readily distinguished strain R142T from all validly published type strains. Strain R142T is therefore suggested to represent a novel species of a new genus, for which the name Exilibacterium tricleocarpae gen. nov., sp. nov. is proposed. The type strain of Exilibacterium tricleocarpae is R142T (=MCCC 1K03816T=KCTC 72138T).

Moderately Halophilic Bacterium

An aerobic, Gram-stain-negative ovoid, designated as strain A21T, was isolated using the dilution-to-extinction method from a soil sample taken from Rambla Salada, an athalassohaline habitat located in Murcia (south-eastern Spain). Strain A21T is non-motile, has a respiratory metabolism and grows at NaCl concentrations within the range 0.5–15 % (w/v) [optimum, 5 % (w/v)], at 5–35 °C (optimum, 28 °C) and at pH 6–8 (optimum, pH 7.0). This strain is positive for catalase activity, oxidase activity and nitrate reduction. The 16S rRNA gene sequence indicates that it belongs to the genus Roseovarius in the class Alphaproteobacteria . The most closely related species are Roseovarius pacificus and Roseovarius halotolerans to which the strain A21T shows 16S rRNA gene sequence similarity values of 98.06 and 97.7 %, respectively. The average nucleotide identity in blast and digital DNA–DNA hybridization values between strain A21T and R. pacificus LMG 24575T are 76.8 and 21 %, respectively. The DNA G+C content based on the genome is 61.28 mol%. The major fatty acids (>5 % of the total fatty acids) of strain A21T are C18 : 1 ω7c/C18 : 1 ω6c and C16 : 0. The only detected isoprenoid quinone in strain A21T is ubiquinone 10 (Q-10). The polar lipid profile contains phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol and three unidentified polar lipids. Based on the phylogenetic, genotypic, phenotypic and chemotaxonomic data, the strain represents a novel species of the genus Roseovarius , for which the name Roseovarius bejariae sp. nov. is proposed. Strain A21T (=CECT 9817T=LMG 31311T) is the type strain.

A Gram-stain-negative, strictly aerobic and rod-shaped motile bacterium with peritrichous flagella, designated strain LZB041T, was isolated from offshore surface seawater of the East China Sea. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain LZB041T formed a lineage within the family ‘ Aurantimonadaceae ’ that was distinct from the most closely related genera Aurantimonas (96.0–96.4 % 16S rRNA gene sequence similarity) and Aureimonas (94.5–96.0 %). Optimal growth occurred in the presence of 1–7 % (w/v) NaCl, at pH 7.0–8.0 and at 28–37 °C. Ubiquinone-10 was the predominant respiratory quinone. The major fatty acids (>10 % of total fatty acids) were C18 : 1ω7c and/or C18 : 1ω6c (summed feature 8) and cyclo-C19 : 0ω8c. The major polar lipids were phosphatidylglycerol, diphosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine, phosphatidylmonomethylethanolamine, one unknown aminolipid, one unknown phospholipid and one unknown polar lipid. The DNA G+C content of strain LZB041T was 71.3 mol%. On the basis of polyphasic analysis, strain LZB041T is considered to represent a novel species of a new genus in the class Alphaproteobacteria , for which the name Jiella aquimaris gen. nov., sp. nov. is proposed. The type strain of the type species is LZB041T ( = JCM 30119T = MCCC 1K00255T).

ABSTRACTThe microbial composition of artisan and industrial animal rennet pastes was studied by using both culture-dependent and -independent approaches. Pyrosequencing targeting the 16S rRNA gene allowed to identify 361 operational taxonomic units (OTUs) to the genus/species level. Among lactic acid bacteria (LAB),Streptococcus thermophilusand some lactobacilli, mainlyLactobacillus crispatusandLactobacillus reuteri, were the most abundant species, with differences among the samples. Twelve groups of microorganisms were targeted by viable plate counts revealing a dominance of mesophilic cocci. All rennets were able to acidify ultrahigh-temperature-processed (UHT) milk as shown by pH and total titratable acidity (TTA). Presumptive LAB isolated at the highest dilutions of acidified milks were phenotypically characterized, grouped, differentiated at the strain level by randomly amplified polymorphic DNA (RAPD)-PCR analysis, and subjected to 16S rRNA gene sequencing. Only 18 strains were clearly identified at the species level, asEnterococcus casseliflavus,Enterococcus faecium,Enterococcus faecalis,Enterococcus lactis,Lactobacillus delbrueckii, andStreptococcus thermophilus, while the other strains, all belonging to the genusEnterococcus, could not be allotted into any previously described species. The phylogenetic analysis showed that these strains might represent different unknown species. All strains were evaluated for their dairy technological performances. All isolates produced diacetyl, and 10 of them produced a rapid pH drop in milk, but only 3 isolates were also autolytic. This work showed that animal rennet pastes can be sources of LAB, mainly enterococci, that might contribute to the microbial diversity associated with dairy productions.

A novel nitrogen-fixing strain, designated HL-12T, was isolated from a freshwater lake in Taiwan. Cells of strain HL-12T were aerobic, Gram-negative, motile rods that were surrounded by a thick capsule, contained poly-β-hydroxybutyrate granules, and formed light-yellow to brownish-red colonies. Growth occurred at 15–40 °C (optimum 25–35 °C), at pH 6.0–7.0 (optimum pH 6.0) and with 0–4 % NaCl (optimum 0–1 %). Phylogenetic analysis based on 16S rRNA gene sequences showed that strain HL-12T belonged to the genus Derxia and exhibited 99.1 and 98.8 % 16S rRNA gene sequence similarity, respectively, with Derxia gummosa IAM 14990 and D. gummosa IAM 13946T. The major fatty acids (>10 %) of strain HL-12T were summed feature 3 (comprising C16 : 1ω7c and/or C16 : 1ω6c), C16 : 0 and C18 : 1ω7c. The cellular hydroxy fatty acids were C12 : 0 3-OH, C14 : 0 2-OH and C14 : 0 3-OH. The isoprenoid quinone was Q-8 and the DNA G+C content was 72.0 mol%. The polar lipid profile contained phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol and several unknown aminophospholipids and phospholipids. DNA–DNA relatedness between strain HL-12T and LMG 3975 and LMG 3977T was <70 %. On the basis of the genotypic and phenotypic data, strain HL-12T represents a novel species in the genus Derxia , for which the name Derxia lacustris sp. nov. is proposed. The type strain is HL-12T ( = BCRC 80208T  = KCTC 23311T).

Two strains, 8-4-E12T and 8-4-E13T, were isolated from a biowaste composting reactor. Based on 16S rRNA gene sequences, both strains belong to the genus Bacillus . Strain 8-4-E12T was most closely related to the type strains of Bacillus shackletonii , B. acidicola , B. sporothermodurans and B. oleronius (96.4, 96.3, 96.0 and 95.6 % 16S rRNA gene similarity, respectively), whereas strain 8-4-E13T was most closely related to the type strain of Bacillus humi (96.5 % sequence similarity). Strains 8-4-E12T and 8-4-E13T shared 94 % 16S rRNA gene sequence similarity. The fatty acid profile of strain 8-4-E12T was dominated by saturated iso- and anteiso-branched fatty acids (iso-C15 : 0, anteiso-C15 : 0, anteiso-C17 : 0 and iso-C16 : 0), and also contained considerable amounts of C16 : 0. The fatty acid profile of strain 8-4-E13T showed a predominance of iso-C15 : 0 (65 %), with smaller amounts of other saturated branched-chain fatty acids along with an unsaturated alcohol. Both strains contained diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine as major polar lipids. Additionally, strain 8-4-E12T contained an unknown lipid and strain 8-4-E13T two unknown (amino-)phospholipids. The diagnostic diamino acid found in the cell-wall peptidoglycan of 8-4-E12T and 8-4-E13T was meso-diaminopimelic acid. The predominant menaquinone was MK-7. The results of physiological and biochemical tests also allowed phenotypic differentiation of the two strains from each other and from related Bacillus species. On the basis of their phylogenetic, phenotypic and chemotaxonomic properties, strains 8-4-E12T and 8-4-E13T represent novel species of the genus Bacillus , for which the names Bacillus pervagus sp. nov. (type strain 8-4-E12T = DSM 23947T = LMG 27601T) and Bacillus andreesenii sp. nov. (type strain 8-4-E13T = DSM 23948T = LMG 27602T) are proposed.

A novel actinomycete, strain 44EHWT, was isolated from rhizospheric soil under an Elephant ear plant (Colocasia esculenta) in Bangkok, Thailand. Strain 44EHWT produced long branching hyphae and abundant aerial mycelia with chains of rod-shaped spores. Whole-cell hydrolysates contained galactose, glucose, arabinose, ribose, mannose and rhamnose as diagnostic sugars. meso-Diaminopimelic acid was the diamino acid and glycine, alanine and glutamic acid were present in the cell-wall peptidoglycan with the acyl type of the peptidoglycan being acetyl. Phospholipids consisted of phosphatidylethanolamine, phosphatidylethanolamine with hydroxy fatty acids and diphosphatidylglycerol, as well as other unknown phospholipids; however, no mycolic acids were detected. The predominant menaquinone observed was MK-9(H4) and major fatty acids were iso-C16 : 0 and 2-OH iso-C16 : 0. The G+C content of genomic DNA was 74 mol%. Phylogenetic analysis based on 16S rRNA gene sequences revealed that this isolate was most similar to Actinokineospora enzanensis NBRC 16517T. However, DNA–DNA hybridization revealed a low relatedness between this isolate and A. enzanensis NBRC 16517T, indicating that this isolate represented a novel species in the genus Actinokineospora . On the basis of 16S rRNA gene sequence analysis, phenotypic characteristics and DNA–DNA hybridization data, we propose that strain 44EHWT represents a novel species in the genus Actinokineospora , Actinokineospora bangkokensis. The type strain is 44EHWT ( = BCC 53155T = NBRC 108932T).

Bacterial strain M47C3BT was isolated from the endophytic microbial community of a Pinus pinaster tree branch from a mixed grove of pines. Phylogenetic analysis of 16S rRNA gene sequences showed that this organism represented one distinct branch within the family Sphingobacteriaceae , most closely related to the genus Mucilaginibacter . Strain M47C3BT formed a distinct lineage, closely related to Mucilaginibacter dorajii KACC 14556T, with which it shared 97.2 % 16S rRNA gene sequence similarity. The other members of the genus Mucilaginibacter included in the same clade were Mucilaginibacter lappiensis ATCC BAA-1855T sharing 97.0 % similarity and Mucilaginibacter composti TR6-03T that had a lower similarity (95.7 %). The novel strain was Gram-staining-negative, formed rod-shaped cells, grew optimally at 26 °C and at pH 7, and was able to grow with up to 0.3 % (w/v) NaCl. The respiratory quinone was menaquinone 7 (MK-7) and the major fatty acids of the strain were summed feature 3 (C16 : 1ω7c/iso-C15 : 0 2-OH), iso-C15 : 0 and iso-C17 : 0 3-OH, representing 73.5 % of the total fatty acids. The major components of the polar lipid profile of strain M47C3BT consisted of phosphatidylethanolamine, three unidentified aminophospholipids, one unidentified aminolipid and three unidentified polar lipids. The G+C content of the DNA was 40.6 mol%. On the basis of the phylogenetic analysis and physiological and biochemical characteristics we propose the name Mucilaginibacter pineti sp. nov. for the novel species represented by strain M47C3BT ( = CIP 110632T = LMG 28160T).
