| gram-negative anaerobic bacteria | <microbiology> A large group of anaerobic bacteria which show up as pink (negative) when treated by the gram-staining method. (12 Dec 1998) |
|---|---|
| gram-negative bacteria | <microbiology> Bacteria which lose crystal violet stain but are stained pink when treated by gram's method. (12 Dec 1998) |
| gram-negative chemolithotrophic bacteria | <microbiology> A large group of bacteria including those which oxidise ammonia or nitrite, metabolise sulfur and sulfur compounds, or deposit iron and/or manganese oxides. (12 Dec 1998) |
| gram-negative oxygenic photosynthetic bacteria | <microbiology> Widely distributed unicellular or multicellular bacteria. The cyanobacteria use chlorophyll a and phycobilins for oxygenic photosynthesis while genera in the prochlorales use both chlorophyll a and b but not phycobilins. (12 Dec 1998) |
| gram-positive bacteria | <microbiology> Bacteria which retain the crystal violet stain when treated by gram's method. (12 Dec 1998) |
| gram-positive endospore-forming bacteria | <microbiology> Bacteria that form endospores and are gram-positive. Representative genera include bacillus, clostridium, micromonospora, saccharopolyspora, and streptomyces. (12 Dec 1998) |
| green bacteria | <microbiology> Anoxygenic phototrophs containing chlorosomes and bacteriochlorophyll c, cs, d or e and light harvesting chlorophyll. (09 Oct 1997) |
| green sulfur bacteria | A group of green or brown bacteria of the families chlorobiaceae and chloroflexaceae that occur in aquatic sediments, sulfur springs, and hot springs and that utilise reduced sulfur compounds instead of oxygen. (12 Dec 1998) |
| photosynthetic bacteria | <microbiology> Bacteria that are able to carry out photosynthesis. Light is absorbed by bacteriochlorophyll and carotenoids. Two principal classes are the green bacteria and the purple bacteria. (31 Dec 1997) |
| phototrophic bacteria | A physiological community of gram-negative bacteria whose members can perform photosynthesis under anaerobic conditions. (12 Dec 1998) |
| coliform bacteria | Bacteria whose presence in waste water is an indicator of pollution and of potentially dangerous contamination. (05 Dec 1998) |
| haemophilic bacteria | <microbiology> Haemophilic bacteria are bacteria which thrive in the presence of blood. These bacteria all belong to the taxonomic genera of Haemophilus, Bordetella, and Moraxella. They are rod-shaped, gram-negative, nonmotile parasites. (09 Oct 1997) |
| purple sulphur bacteria | <microbiology> A group of phototrophic prokaryotes containing bacteriochlorophylls a or b and characterised by the ability to oxidize hydrogen sulphide (H2S) and store elemental sulphur inside the cells. (09 Oct 1997) |
| spiral and curved bacteria | A large, very diverse group of bacteria in which some species are curved, some helical. (12 Dec 1998) |
| sulfur-reducing bacteria | A group of gram-negative, anaerobic bacteria that is able to oxidise acetate completely to carbon dioxide using elemental sulfur as the electron acceptor. (12 Dec 1998) |
