Query: NC_016940:1698000 Saprospira grandis str. Lewin chromosome, complete genome Lineage: Saprospira grandis; Saprospira; Saprospiraceae; Sphingobacteriales; Bacteroidetes; Bacteria General Information: Gliding bacterium. Saprospira grandis is a gram-negative, marine, multicellular, filamentous flexibacterium. They prey on other bacteria by trapping and devouring them. It is significant because it is known for devouring bacteria and also has been shown to digest algae by the same process. This makes this bacterium important because it is useful in preventing harmful algal blooms. They are mesophilic with their optimum temperature being between 25-30 degrees C, and require a neutral pH. This filamentous organism is matile by gliding. This organism is able to lyse bacterial cells on the surfaces it is moving over.

General Information: This strain was isolated from commercial yogurt in 1974 in the United Kingdom. Lactic acid producing bacterium used in cheese and yogert production. Streptococci are Gram-positive, nonmotile, nonsporeforming, catalase-negative cocci that occur in pairs or chains. Members of this genus vary widely in pathogenic potential. Most streptococci are facultative anaerobes, and some are obligate anaerobes. Serologic grouping is based on antigenic differences in cell wall carbohydrates, in cell wall pili-associated protein, and in the polysaccharide capsule in group B streptococci. This organism is a lactic acid bacteria often used as a starter culture for fermented dairy products including yogurt and cheese.
