The Family

A novel marine, Gram-stain-negative, oxidase- and catalase- positive, rod-shaped bacterium, designated strain AK6T, was isolated from marine aquaculture pond water collected in Andhra Pradesh, India. The fatty acids were dominated by iso-C15 : 0, iso-C17 : 1ω9c, iso-C15 : 1 G, iso-C17 : 0 3-OH and anteiso-C15 : 0. Strain AK6T contained MK-7 as the sole respiratory quinone and phosphatidylethanolamine, one unidentified aminophospholipid, one unidentified phospholipid and seven unidentified lipids as polar lipids. The DNA G+C content of strain AK6T was 45.6 mol%. Phylogenetic analysis showed that strain AK6T formed a distinct branch within the family Cyclobacteriaceae and clustered with Aquiflexum balticum DSM 16537T and other members of the family Cyclobacteriaceae . 16S rRNA gene sequence analysis confirmed that Aquiflexum balticum DSM 16537T was the nearest neighbour, with pairwise sequence similarity of 90.1 %, while sequence similarity with the other members of the family was <88.5 %. Based on differentiating phenotypic characteristics and phylogenetic inference, strain AK6T is proposed as a representative of a new genus and species of the family Cyclobacteriaceae , as Mariniradius saccharolyticus gen. nov., sp. nov. The type strain of Mariniradius saccharolyticus is AK6T ( = MTCC 11279T = JCM 17389T). Emended descriptions of the genus Aquiflexum and Aquiflexum balticum are also proposed.

Aquaculture Pond

A rod-shaped, phototrophic, purple sulfur bacterium, strain JA124T, was isolated in pure culture from a marine aquaculture pond, located near Bhimunipatnam, in a medium that contained 3 % NaCl (w/v). Strain JA124T is a Gram-negative, motile rod with a single polar flagellum. Strain JA124T has a requirement for NaCl, with optimum growth at 1.5–8.5 %, and tolerates up to 11 % NaCl. Intracellular photosynthetic membranes are of the vesicular type. Bacteriochlorophyll a and probably carotenoids of the spirilloxanthin series are present as photosynthetic pigments. Strain JA124T was able to utilize sulfide, sulfate, thiosulfate, sulfite, thioglycollate and cysteine as sulfur sources. Strain JA124T was able to grow photolithoautotrophically, photolithoheterotrophically and photo-organoheterotrophically. Chemotrophic and fermentative growth could not be demonstrated. Strain JA124T lacks diazotrophic growth and acetylene reduction activity. Pyridoxal phosphate is required for growth. During growth on reduced sulfur sources as electron donors, sulfur is deposited intermediately as a number of small granules within the cell. Phylogenetic analysis on the basis of 16S rRNA gene sequences showed that strain JA124T clusters with species of the genus Marichromatium belonging to the class Gammaproteobacteria. The highest sequence similarities of strain JA124T were found with the type strains of Marichromatium indicum (98 %), Marichromatium purpuratum (95 %) and Marichromatium gracile (93 %). However, DNA–DNA hybridization with Marichromatium indicum DSM 15907T revealed relatedness of only 65 % with strain JA124T. The DNA base composition of strain JA124T was 67 mol% G+C (by HPLC). Based on 16S rRNA gene sequence analysis, morphological and physiological characteristics and DNA–DNA hybridization studies, strain JA124T (=ATCC BAA-1316T=JCM 13911T) is sufficiently different from other Marichromatium species to merit its description as the type strain of a novel species, Marichromatium bheemlicum sp. nov.

The Stability

As well as being a culture environment for fish and crustaceans, an aquaculture pond is a rich and complex ecosystem that is dominated by the microbial community. The community is nourished by food and sunlight, and is made up of algae, bacteria and, importantly, protozoa. Protozoa live by eating other organisms and detritus, or by absorbing soluble organic matter dissolved in the water. Ultimately they affect water quality in aquaculture ponds, including the stability of algal and bacterial communities, and nutrient concentrations. In addition, some protozoa can have adverse effects on the health of cultured species. Guide to Protozoa of Marine Aquaculture Ponds is designed to provide a simple means of identifying the main groups of protozoa found in aquaculture ponds through the use of photographs and drawings. This is supplemented with information on the likely effects of protozoa on water quality and the health of the cultured species. This guide is an indispensable tool for those involved in rearing marine animals, as well as aquaculture researchers and teachers. Please note that this book is spiral-bound.
