| lactic acid bacteria | <microbiology> A group of Gram-positive, non-sporing bacteria which carry out a lactic acid fermentation of sugars. It includes species of Lactobacillus, Leuconostoc, Pediococcus and Streptococcus. See: lactic acid fermentation. (25 Jun 1999) |

| lysogenic bacteria | <microbiology> A bacterium which contains in its genome the DNA of a virus which is lying dormant, passively letting itself be replicated by the bacterium whenever the bacterium replicates its own genome (a lysogenic virus), but able to reactivate and destroy the bacterium at a time of the virus's choosing (becomes a lytic virus). (15 Oct 1997) |
| african green monkey kidney cell | <cell culture> Cells taken from the kidneys of the African green monkey Cercopithecus aethiops sabaeus and used to grow certain viruses like poliovirus. (05 Feb 1998) |
| algae, green | Algae of the division chlorophyta, in which the green pigment of chlorophyll is not masked by other pigments. Classes include charophyceae, bryopsidophyceae, conjugatophyceae, oedogoniophyceae, chlorophyceae, and prasinophyceae. Common genera are acetabularia, chlamydomonas, chlorella, nitella, prototheca, scenedesmus, spirogyra, and volvox. (12 Dec 1998) |
| blue-green algae | The former name for the blue-green bacteria, now classified as Cyanobacteria. A group of prokaryotes. Synonym: Cyanobacteria. (05 May 2002) |
| blue-green bacterium | <organism> Modern term for the blue green algae, prokaryotic cells that use chlorophyll on intracytoplasmic membranes for photosynthesis. The blue green colour is due to the presence of phycobiliproteins. Found as single cells, colonies or simple filaments. In Anabaena, in which the cells are arranged as a filament, heterocysts capable of nitrogen fixation occur at regular intervals. According to the endosymbiont theory Cyanobacteria are the progenitors of chloroplasts. (18 Nov 1997) |
| brilliant green | The sulfate of di-(p-diethylamino)-triphenyl carbinolanhydride. An indicator dye that changes from yellow to green at pH 0.0 to 2.6; also used as a topical antiseptic and as a selective bacteriostatic agent in culture media. Synonym: ethyl green. (05 Mar 2000) |

| bromcresol green | <chemical> An indicator and reagent. It has been used in serum albumin determinations and as a pH indicator. Pharmacological action: indicators and reagents. Chemical name: Phenol, 4,4'-(3H-2,1-benzoxathiol-3-ylidene)bis(2,6-dibromo-3-methyl-, S,S-dioxide (12 Dec 1998) |
| bromocresol green | Tetrabromo-m-cresolsulfonphthalein;an indicator dye changing from yellow to blue at pH 4.7; used to track DNA in agarose electrophoresis, and in a dye-binding method for analysis of serum albumin. (05 Mar 2000) |
