Query: NC_014976:2231984 Bacillus subtilis BSn5 chromosome, complete genome

Lineage: Bacillus subtilis; Bacillus; Bacillaceae; Bacillales; Firmicutes; Bacteria

General Information: Bacillus subtilis BSn5 was isolated from Amorphophallus konjac calli tissue culture. Bacilllus subtilis BSn5 could inhibit Erwinia carotovora subsp. carotovora strain SCG1, which causes Amorphophallus soft rot disease and affects Amorphophallus industry development This organism was one of the first bacteria studied, and was named Vibrio subtilis in 1835 and renamed Bacillus subtilis in 1872. It is one of the most well characterized bacterial organisms, and is a model system for cell differentiation and development. This soil bacterium can divide asymmetrically, producing an endospore that is resistant to environmental factors such as heat, acid, and salt, and which can persist in the environment for long periods of time. The endospore is formed at times of nutritional stress, allowing the organism to persist in the environment until conditions become favorable. Prior to the decision to produce the spore the bacterium might become motile, through the production of flagella, and also take up DNA from the environment through the competence system.The sporulation process is complex and involves the coordinated regulation of hundreds of genes in the genome. This initial step results in the coordinated asymmetric cellular division and endospore formation through multiple stages that produces a single spore from the mother cell.

Subject: NC_014334:769205 Lactobacillus casei str. Zhang chromosome, complete genome

Lineage: Lactobacillus casei; Lactobacillus; Lactobacillaceae; Lactobacillales; Firmicutes; Bacteria

General Information: Lactobacillus casei str. Zhang was isolated from traditional home-made koumiss (fermented mare's milk) in Inner Mongolia, China. This strain has the potential probiotic properties such as high resistance to acidic pH and bile salt. They are commonly found in the oral, vaginal, and intestinal regions of many animals. They are important industrial microbes that contribute to the production of cheese, yogurt, fermented milks, and other products, all stemming from the production of lactic acid, which inhibits the growth of other organisms as well as lowering the pH of the food product. Industrial production requires the use of starter cultures, which are carefully created, cultivated, and maintained, which produce specific end products during fermentation that impart flavor to the final product, as well as contributing important metabolic reactions, such as the breakdown of milk proteins during cheese production. The end product of fermentation, lactic acid, is also being used as a starter molecule for complex organic molecule syntheses. Lactobacillus casei is used as a starter culture during milk fermentation and for the flavor development of certain bacterial-ripened cheeses.
