Choanoflagellates offer key insights into bacterial influences on the origin and early evolution of animals. Here we report the isolation and characterization of a new colonial choanoflagellate species, Salpingoeca monosierra, that, unlike previously characterized species, harbors a stable microbiome. S. monosierra was isolated from Mono Lake, California and forms large spherical colonies that are more than an order of magnitude larger than those formed by the closely related S. rosetta. By designing fluorescence in situ hybridization probes from metagenomic sequences, we found that S. monosierra colonies are colonized by members of the halotolerant and closely related Saccharospirillaceae and Oceanospirillaceae, as well as purple sulfur bacteria (Ectothiorhodospiraceae) and non-sulfur Rhodobacteraceae. This relatively simple microbiome in a close relative of animals presents a new experimental model for investigating the evolution of stable interactions among eukaryotes and bacteria.

Sewage contains high concentration of sulfate and contaminates ground water supply. The production process in the factory produced sewage containing high amount of sulfur such as sulphide and sulphate. Sulfur bacteria, which are capable of oxidizing, reducing or partially oxidizing inorganic sulfur compounds such as Thiomicrospira, Thiothrix, Desulforomonas, Achromatium, and a group of Thiobacillus. Utilization of sulfur bacteria has done in attemp to find sewage bioremediation agents as well as to promote soil fertility. Isolation and characterization were carried out by growing the bacteria in the starkey selective medium, including pH reduction test, morphology, physiology and biochemical characterization. It has been observed that out of 2 isolates from different sources of samples (rubber and paper sewage), only one isolates related to sulfur-oxidizing bacterium (SOB) while  the isolates AE01 related to true sulfur-oxidizing bacterium in genus Thiobacillus.

ABSTRACT Bacterial strains CVO and FWKO B were isolated from produced brine at the Coleville oil field in Saskatchewan, Canada. Both strains are obligate chemolithotrophs, with hydrogen, formate, and sulfide serving as the only known energy sources for FWKO B, whereas sulfide and elemental sulfur are the only known electron donors for CVO. Neither strain uses thiosulfate as an energy source. Both strains are microaerophiles (1% O2). In addition, CVO grows by denitrification of nitrate or nitrite whereas FWKO B reduces nitrate only to nitrite. Elemental sulfur is the sole product of sulfide oxidation by FWKO B, while CVO produces either elemental sulfur or sulfate, depending on the initial concentration of sulfide. Both strains are capable of growth under strictly autotrophic conditions, but CVO uses acetate as well as CO2 as its sole carbon source. Neither strain reduces sulfate; however, FWKO B reduces sulfur and displays chemolithoautotrophic growth in the presence of elemental sulfur, hydrogen, and CO2. Both strains grow at temperatures between 5 and 40°C. CVO is capable of growth at NaCl concentrations as high as 7%. The present 16s rRNA analysis suggests that both strains are members of the epsilon subdivision of the division Proteobacteria, with CVO most closely related toThiomicrospira denitrifcans and FWKO B most closely related to members of the genus Arcobacter. The isolation of these two novel chemolithotrophic sulfur bacteria from oil field brine suggests the presence of a subterranean sulfur cycle driven entirely by hydrogen, carbon dioxide, and nitrate.
