| 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) |
| 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) |
| endospore-forming bacteria | A group of rods or cocci whose taxonomic affinities are uncertain. They form endospores, thick-walled bodies formed within the vegetative cells of certain bacteria, able to withstand adverse environmental conditions for prolonged periods. (12 Dec 1998) |
| endosymbiotic bacteria | Bacteria that establish a symbiotic relationship within a eukaryotic cell. For example the nitrogen fixing bacteria of legume root nodules. See: endosymbiont hypothesis. (18 Nov 1997) |
| enteric bacteria | A large group of Gram negative rod-shaped bacteria characterised by a facultatively aerobic metabolism. Many of them are commonly found in the intestines of animals. (09 Oct 1997) |
