Weissella is a genus of gram-positive bacteria placed within the family Lactobacillaceae, formerly considered species of the Leuconostoc paramesenteroides group. The morphology of Weissella species varies from spherical or lenticular cells to irregular rods. Several strains of Weissella cibaria and Weissella confusa have shown probiotic potential. In particular, the cell-free culture supernatant of Weissella confusa shows a number of beneficial characteristics, such as antibacterial potential and anti-inflammatory efficiency. However, several strains of W. confusa are opportunistic bacteria. A number of studies have been done on the safety of the bacterial species, indicating their probiotic potential. The Senate Commission on Food Safety has validated the use of W. confusa in food.
Weissella hellenica is a species of Gram-positive bacteria, placed within the family of Leuconostocaceae. It is frequently isolated from fermented sausage and flounder intestine, as well as Korean fermented pickle Kimchi and barrels used to make Japanese pickles. Some strains have been observed to be probiotic while some have not. Some strains produce bacteriocins named weissellicins which show antimicrobial activity against other bacteria.
Lactobacillus gallinarum is a species in the genus Lactobacillus. Its type strain is ATCC 33199.
Brucella ceti is a gram negative bacterial pathogen of the Brucellaceae family that causes brucellosis in cetaceans. Brucella ceti has been found in both classes of cetaceans, mysticetes and odontocetes. Brucellosis in some dolphins and porpoises can result in serious clinical signs including fetal abortions, male infertility, neurobrucellosis, cardiopathies, bone and skin lesions, stranding events, and death.
Psychrobacter is a genus of Gram-negative, osmotolerant, oxidase-positive, psychrophilic or psychrotolerant, aerobic bacteria which belong to the family Moraxellaceae and the class Gammaproteobacteria. The shape is typically cocci or coccobacilli. Some of those bacteria were isolated from humans and can cause humans infections such as endocarditis and peritonitis. This genus of bacteria is able to grow at temperatures between −10 and 42 °C. Rudi Rossau found through DNA-rRNA hybridization analysis that Psychrobacter belongs to the Moraxellaceae. The first species was described by Juni and Heym. Psychrobacter occur in wide range of moist, cold saline habitats, but they also occur in warm and slightly saline habitats.
Ligilactobacillus acidipiscis is a species in the genus Ligilactobacillus. It is a homofermentative, rod-shaped lactic acid bacteria. Its type strain is FS60-1T.
