The employment of multi-species starter cultures has growing importance in modern winemaking for improving the complexity and wine attributes. The assessment of compatibility for selected species/strains at the industrial-scale is crucial to assure the quality and the safety associated with fermentations. An aspect particularly relevant when the species belong to non-Saccharomyces, Saccharomyces spp. and malolactic bacteria, three categories with different biological characteristics and oenological significance. To the best of our knowledge, the present report is the first study regarding the utilization of a combined starter culture composed of three strains of non-Saccharomyces, Saccharomyces cerevisiae and Lactobacillus plantarum for production of wine at the industrial scale. More in-depth, this work investigated the oenological potential of the autochthonous characterized strains from the Apulian region (Southern Italy), Candida zemplinina (syn. Starmerella bacillaris) 35NC1, S. cerevisiae (NP103), and L. plantarum (LP44), in co-inoculation following a complete scale-up scheme. Microbial dynamics, fermentative profiles and production of volatile secondary compounds were assessed in lab-scale micro-vinification tests and then the performances of the mixed starter formulation were further evaluated by pilot-scale wine production. The above results were finally validated by performing an industrial-scale vinification on 100HL of Negroamaro cultivar grape must. The multi-starter formulation was able to rule the different stages of the fermentation processes effectively, and the different microbial combinations enhanced the organoleptic wine features to different extents. The findings indicated that the simultaneous inoculation of the three species affect the quality and quantity of several volatile compounds, confirming that the complexity of the wine can reflect the complexity of the starter cultures. Moreover, the results underlined that the same mixed culture could differently influence wine quality when tested at the lab-, pilot- and industrial-scale. Finally, we highlighted the significance of employment non-Saccharomyces and L. plantarum, together with S. cerevisiae, autochthonous strains in the design of custom-made starter culture formulation for typical regional wine production with pronounced unique quality.

The aim of this study was to develop a nondairy fermented product based on mango slurry. Lactobacillus plantarum and Saccharomyces cerevisiae DV10 were used as starter cultures in single and co-cultivations. The microbial populations and metabolites produced during mango slurry fermentation were investigated. At the end of all fermentations, the bacterial populations were higher than 6.0 log CFU/mL. Lactic acid was the main organic acid produced, achieving up to 6.12 g/L after 24 h in co-culture with L. plantarum and S. cerevisiae DV10. Volatile compounds were determined after 24 h of fermentation, the co-cultures of L. plantarum and S. cerevisiae DV10 could decrease terpenes and produce alcohols and esters. The co-cultivations obtained the most total phenolics as well as showed the strongest 2,2′-azinobis-(3-ethylbenzothiazoline-6-sulfonate) (ABTS) radical scavenging activity, ferric-reducing antioxidant power (FRAP) and low-density lipoprotein (LDL) oxidation inhibition. Hence, a high-bioactivity probiotic product was successfully obtained via mango slurry fermentation inoculated with a co-culture of L. plantarum and S. cerevisiae DV10.

Ginger, red pepper, mustard, mace, cinnamon and clove were examined to determine their effects on growth of and acid production by a starter culture containing Lactobacillus plantarum and Pediococcus cerevisiae in a liquid medium. At 4, 8, and 12 g/l levels all spices except clove stimulated acid production by the starter bacteria but did not stimulate increases in bacterial population. Clove was inhibitory to the starter bacteria at and above the 4 g/l level, but low concentrations (0.5 – 2.0 g/l) stimulated acid production. High concentrations of cinnamon (8 and 12 g/l) delayed acid production, but bacterial counts were similar to those of the control.

Malting is an important industrial product with a huge market outlet. Sorghum grain carries a numerous and variable, microbial population that mainly consists of bacteria, yeasts, and filamentous fungi. Sorghum malt is heavily reliant on chemical control of moulds and coliforms. This research aimed at investigating ways of improving malt quality and safety, using starter cultures of lactic acid bacteria and yeast, during the steeping stage of malting. All the steep treatments contained a sizeable population of moulds, greater than 4logcfu/mL, at 0hrs of steeping. A 3Log decrease was recorded in the steep treatment containing only single culture of Lactobacillus plantarum All the steeping treatments achieved varying levels of anti-nutrient reduction. The Lactobacillus plantarum CLB8 steep reduced the phytate level by as much as 47% when compared to the phytate level in sorghum grain. The combined cultures of Lactobacillus plantarum CLB8 and Saccharomyces cerevisiaeCYT1 reduced the phytate content by as much as 40% when compared to the sorghum grain without treatment. When compared to the control steep, the Lactobacillus plantarum CLB8 steep improved the anti-nutrient degradation by 31%. The combined cultures of Lactobacillus plantarum CLB8 and Saccharomyces cerevisiae CYT1 reduced the phytate content by as much as 23% when compared with the control steep. The polyphenol content was reduced by about 46% in the Lactobacillus plantarum CLB8 steep and 29% in the combined cultures of Lactobacillus plantarum CLB8 and Saccharomyces cerevisiae CYT1 steep when compared to the polyphenol content in the whole sorghum grain. Only the Lactobacillus plantarum CLB8 steep had better polyphenol reduction than the control with a 9.6% reduction more than the control. It was concluded that lactic acid bacteria can be apply as a biological control organism in malting of grains.

Malolactic fermentation (MLF) in wine is an important step in the vinification of most red and some white wines, as stands for the biological conversion of l-malic acid into l-lactic acid and carbon dioxide, resulting in a decrease in wine acidity. MLF not only results in a biological deacidification, it can exert a significant impact on the organoleptic qualities of wine. This paper reviews the biodiversity of lactic acid bacteria (LAB) in wine, their origin, and the limiting conditions encountered in wine, which allow only the most adapted species and strains to survive and induce malolactic fermentation. Of all the species of wine LAB, Oenococcus oeni is probably the best adapted to overcome the harsh environmental wine conditions and therefore represents the majority of commercial MLF starter cultures. Wine pH is most challenging, but, as a result of global warming, Lactobacillus sp. is more often reported to predominate and be responsible for spontaneous malolactic fermentation. Some Lactobacillus plantarum strains can tolerate the high alcohol and SO2 levels normally encountered in wine. This paper shows the potential within this species for the application as a starter culture for induction of MLF in juice or wine. Due to its complex metabolism, a range of compositional changes can be induced, which may positively affect the quality of the final product. An example of a recent isolate has shown most interesting results, not only for its capacity to induce MLF after direct inoculation, but also for its positive contribution to the wine quality. Degrading hexose sugars by the homo-fermentative pathway, which poses no risk of acetic acid production from the sugars, is an interesting alternative to control MLF in high pH wines. Within this species, we can expect more strains with interesting enological properties.

Abstract Background: Cassava is a potential energy-rich food crops to make different food products in developing countries but limited by a shortage of protein content and the presence of toxic cyanogenic glycosides.Methods: Cassava-teff flour fermented with three pure starter cultures of Saccharomyces cerevisiae, Lactobacillus plantarum and Lactobacillus coryneformis. Two different inoculum levels (0.5 and 1.5 ml) were used. 300 g of cassava-teff flour were fermented with each of single starter cultures at 24 and 48 h. Results: The analysis of pH, crude protein and cyanide content indicates fermentation samples with Lactobacillus plantarum and Lactobacillus coryneformis for 48 h with 1.5 ml inoculums resulted in highest pH reduction. Similarly, highest reduction cyanide was recorded with 1.5 ml inoculums of Lactobacillus coryneformis and Lactobacillus plantarum, while the least cyanide reduction was recorded in fermentation samples of Saccharomyces cerevisiae at 24 h of 1 ml of inoculum level, but this value is higher when compared upon boiling (47.77 mg/kg). The highest levels of crude protein were observed fermentation samples with 1.5 ml inoculum of Saccharomyces cerevisiae for 48 h. Regarding palatability, the panelist preferred that fermentation sample with 1.5 ml inoculums of Lactobacillus plantarum and Lactobacillus coryneformis at 48 h having the best taste with the score of 4.90 ± 0.17 and 4.87 ± 0.23 respectively over the control, while sample fermented with Saccharomyces cerevisiae was preferred in terms of flavor, texture and overall acceptability with score of 4.87 ± 0.23, 4.73 ± 0.11 and 4.67 ± 0.12 respectively over the control. Conclusions: Therefore, microbial fermentation is a promising candidate for improving nutritional and safety value of cassava- based food and suggested as a choice of the processing method, as this method significantly reduced cyanide content, increased protein content and improved sensory properties of injera.

Current Concern

Sulfites are considered the main additives in winemaking for their antimicrobial, antioxidant and anti-oxidasic activities. The current concern about the potential negative effects of sulfur dioxide (SO2) on consumer health has focused the interest on replacing or reducing SO2 use. Our work aims to develop a strategy based on the use of selected starter culture, able to perform wine fermentation without SO2 addition. Four selected Saccharomyces cerevisiae indigenous strains were tested as mixed starter cultures in laboratory scale fermentations. The starter culture, characterized by a similar percentage of dominance of both strains composing the mixed starter and able to produce a wine characterized by the best combination of chemical and aromatic characteristics, was chosen. This mixed culture was tested as a starter at pilot scale with and without SO2 addition, by using a higher inoculum level in the vinification without SO2. The selected starter confirmed higher dominance ability in vinification without SO2 addition than in SO2-added fermentation, demonstrating that sulfite addition is not a guarantee to reach an absolute dominance of starter culture on indigenous microflora. The proposed biotechnological tool allowed to produce good quality wines possessing also “functional properties”, as NO-SO2 added wines were characterized by high polyphenol content and antioxidant activity.

Fermentation was used since ancient times as an easy method of food preservation, which also maintains and/or improves the nutritional and sensory properties of food. A research as aimed at identifying strain of lactic acid bacteria (LAB) from fermented caridean-shrimp, which properties suitable for starter cultures in food fermentation. A total of 18 LAB stains were obtained from ten different samples, in each sample consisted of commercial LAB strain that isolated from ten samples of caridean-shrimp. The LAB strains from ten samples were screened for resistance to biological barriers (acid and bile salts), and the three most promising strains were selected. The three bacteria strains were isolated from samples of caridean[1]shrimp and were characterized by the API 50 CHL system of identification. Three lactic acid bacteria species were identified and included Lactobacillus plantarum, and Lactobacillus acidophilus. Strain Y’11b,2, Y’11e,2, Y’85,1, which showed probiotic characteristics reducing cell growth of cancer, could be suitable as a starter culture for food fermentation because of its strong acid production and high acid tolerance. This is the first report to describe bacteria, isolated from caridean[1]shrimp, Lactobacillus Plantarum (Y’11b,2, Y’11e,2) and Lactobacillus acidophilus (Y’85,1) which have the probiotic characteristics and the acid tolerance needed for its use as a starter culture in food fermentation.

Cabbage juices were inoculated with various microorganisms (Lactobacillus plantarum 92H, Lactobacillus plantarum CCM 7039, a mixed starter culture consisting of Lactobacillus plantarum 92H and Saccharomyces cerevisiae C11-3) and fermented spontaneously in a thermostat at 22&deg;C for 168 hours. During fermentation, the analytical and sensory parameters were followed. We found that the most suitable bacteria for the fermentation of cabbage juices was Lactobacillus plantarum CCM 7039 (highest production of lactic acid, sufficient decreasing of pH value, highest intensity of harmonic taste and acceptance of odour and taste). Cabbage juices fermented either with the mixed starter culture or spontaneously contained, at the end of fermentation, cadaverine (48.02&ndash;78.68 mg/dm<sup>3</sup>) and putrescine (82.40&ndash;202.95 mg/dm<sup>3</sup>). The contents of histamine and tyramine were under the limit of quantification in all juices. Optimal sensory characteristics were reached during 72<sup>nd</sup> hour of fermentation of cabbage juice inoculated with Lactobacillus plantarum CCM 7039, and during 96<sup>th </sup>hour of fermentation for the other juices. &nbsp;

ABSTRACT Wine production is a complex procedure in which an important role is played by many microorganisms, particularly yeasts and bacteria. In modern wineries, alcoholic fermentation is usually carried out by adding microbial starter cultures of Saccharomyces cerevisiae strains for precisely controlled production. Nowadays, in the Slovak Republic, autochthonous vinification is getting more popular. The present article deals with the comparison of two vinification approaches, namely spontaneous fermentation and fermentation controlled by a standard commercial S. cerevisiae starter, from the point of view of microbiota dynamics and the chemical characteristics of the wines produced. The dynamics of microbial populations were determined during the fermentation process by a 16S and 28S rRNA next-generation sequencing approach. A profile of the volatile compounds during these fermentation processes was identified by solid-phase microextraction (SPME) coupled to gas chromatography-mass spectrometry (GC-MS). In summary, the microbial diversity in the m1 phase (initial must) was higher, despite the presence of the starter culture. In the m3 phase (young wine), the microbiome profiles of both batches were very similar. It seems that the crucial phase in order to study the relationship of the microbiome and the resulting product should be based on the m2 phase (fermented must), where the differences between the autochthonous and inoculated batches were more evident.

A considerable quantity of agricultural produce in Nigeria gets spoilt due to lack of storage facilities and poor storage conditions. An example of such agricultural produce is date palm which is readily available in the northern parts of Nigeria. This study aimed at evaluating the potential of Saccharomyces cerevisiae Y10 isolated from decomposed sugarcane bagasse to produce wine using date palm fruits. The yeast was isolated using yeast extract peptone dextrose agar and was identified by molecular methods. Fermentation of date palm fruit juice was carried out anaerobically for 20 days during which physicochemical parameters and proximate composition were determined using standard methods. The yeast was identified as Saccharomyces cerevisiae Y10 with accession number MG321589. Analysis of physicochemical properties showed that pH dropped from 5.4 to 3.6, titratable acidity increased from 0.25 to 0.71% and specific gravity decreased from 1.1 to 1.01. Proximate composition of produced wine gave low total reducing sugar and low protein of 0.11 and 0.44% respectively and the final alcohol content was 10.4% at the 20th day of fermentation. This study has shown that Saccharomyces cerevisiae Y10 which was isolated from decaying sugarcane bagasse sample has the potential to be used as starter culture for fermentation of date palm for wine production.
