Lactic Acid Bacteria
Lactobacillales are an order of gram-positive, low-GC, acid-tolerant, generally nonsporulating, nonrespiring, either rod-shaped (bacilli) or spherical (cocci) bacteria that share common metabolic and physiological characteristics. These bacteria, usually found in decomposing plants and milk products, produce lactic acid as the major metabolic end product of carbohydrate fermentation, giving them the common name lactic acid bacteria (LAB). Production of lactic acid has linked LAB with food fermentations, as acidification inhibits the growth of spoilage agents. Proteinaceous bacteriocins are produced by several LAB strains and provide an additional hurdle for spoilage and pathogenic microorganisms. Furthermore, lactic acid and other metabolic products contribute to the organoleptic and textural profile of a food item. The industrial importance of the LAB is further evidenced by their generally recognized as safe (GRAS) status, due to their ubiquitous appearance in food and thei ...

Aerococcus
''Aerococcus'' is a genus in the phylum Bacillota (Bacteria). The genus was first identified in 1953 from samples of air and dust as a catalase-negative, gram-positive coccus that grew in small clusters. They were subsequently found in hospital environments and meat-curing brines. It has been difficult to identify as it resembles alpha-hemolytic ''Streptococcus'' on blood agar plates and is difficult to identify by biochemical means. Sequencing of 16S rRNA has become the gold standard for identification, but other techniques such as MALDI-TOF have also been useful for identifying both the genus and species. Etymology The name ''Aerococcus'' derives from the Greek ''aer, aeros'' (ἀήρ, ἀέρος), air; New Latin ''coccus'' (from Greek''kokkos'' (κόκκος)), a berry; New Latin ''Aerococcus'', air coccus. The name was given based on its round shape and that it was first discovered in air samples. Species The genus contains these species: * '' A. christensenii'' Collins ...

Gaffkaemia
Gaffkaemia (gaffkemia in American English) is a bacterial disease of lobsters, caused by the Gram-positive lactic acid bacterium ''Aerococcus viridans'' var. ''homari''. Discovery Gaffkaemia was first discovered in 1947 in American lobsters (''Homarus americanus'') in a holding tank in Maine. It was originally described as "''Gaffkya homari''" by Hitcher and Snieszko, but the genus name ''Gaffkya'' was rejected in 1971, and the gaffkaemia bacterium was recognised as a subspecies or variety of '' Aerococcus viridans'' by Kelly and Evans in 1974. Effects The effects of gaffkaemia infection include lethargy (typically seen as a drooping tail), anorexia and a pink colour on the ventral side of the abdomen, which gives the disease its alternative common name of red tail disease. When lobsters are moribund, they may lie on their sides, and frequently lose appendages. The effects of gaffkaemia are slowed by low temperatures, such that death can occur within two days of infection at , bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abiotrophia
''Abiotrophia'' is a genus of lactic acid bacteria, a family in the phylum Bacillota (Bacteria). Species The genus contains 4 species of coccus shaped species, 2 are former members of the genus ''Streptococcus'', which were transferred in 1995 to the newly coined genus ''Abiotrophia'': * '' A. adiacens'' ( (Bouvet ''et'' ''al''. 1989) Kawamura ''et'' ''al''. 1995; Latin feminine gender adjective ''adiacens'', adjacent, indicating that this organism can grow as satellite colonies adjacent to other bacterial growth.) * '' A. defectiva'' ( (Bouvet ''et'' ''al''. 1989) Kawamura ''et'' ''al''. 1995, comb. nov. (Type species of the genus).; Latin feminine gender adjective ''defectiva'', deficient.) Other 2 are latter additions: * '' A. balaenopterae'' ( Lawson ''et'' ''al''. 1999; New Latin genitive case noun ''balaenopterae'', pertaining to the minke whale, ''Balaenoptera acutorostrata'', from which the organism was isolated.) * '' A. elegans'' ( Roggenkamp ''et'' ''al''. 1999; Latin f ...

Gram-positive
In bacteriology, gram-positive bacteria are bacteria that give a positive result in the Gram stain test, which is traditionally used to quickly classify bacteria into two broad categories according to their type of cell wall. Gram-positive bacteria take up the crystal violet stain used in the test, and then appear to be purple-coloured when seen through an optical microscope. This is because the thick peptidoglycan layer in the bacterial cell wall retains the stain after it is washed away from the rest of the sample, in the decolorization stage of the test. Conversely, gram-negative bacteria cannot retain the violet stain after the decolorization step; alcohol used in this stage degrades the outer membrane of gram-negative cells, making the cell wall more porous and incapable of retaining the crystal violet stain. Their peptidoglycan layer is much thinner and sandwiched between an inner cell membrane and a bacterial outer membrane, causing them to take up the counterstain (saf ...
