| anoxygenic photosynthesis | A type of photosynthesis in green and purple bacteria in which oxygen is not produced. Use of light energy to synthesise ATP by cyclic photophosphorylation without oxygen production in green and purple bacteria. (09 Oct 1997) |
|---|---|
| photosynthesis | <biochemistry, biology> Process by which green plants, algae and some bacteria absorb light energy and use it to synthesise organic compounds (initially carbohydrates). In green plants, occurs in chloroplasts, that contain the photosynthetic pigments. Occurs by slightly different processes in C3 and C4 plants. (18 Nov 1997) |
| oxygenic photosynthesis | Use of light energy to synthesise ATP and NADPH by noncyclic photophosphorylation with the production of oxygen from water. (09 Oct 1997) |
| Z scheme of photosynthesis | <biochemistry, biology> A schematic representation of the light reactions of photosynthesis, in which the photosynthetic reaction centres and electron carriers are arranged according to their electrode potential (free energy) in one dimension and their reaction sequence in the second dimension. This gives a Z shape, the two reaction centres (of photosystems I and II) being linked by the photosynthetic electron transport chain. (18 Nov 1997) |
| acute bacterial endocarditis | A type of bacterial endocarditis caused by pyogenic organisms such as haemolytic streptococci or staphylococci. (05 Mar 2000) |
| adhesins, bacterial | Cell-surface components or appendages of bacteria that facilitate adhesion (bacterial adhesion) to other cells or to inanimate surfaces. most fimbriae (fimbriae, bacterial) of gram-negative bacteria function as adhesins, but in many cases it is a minor subunit protein at the tip of the fimbriae that is the actual adhesin. In gram-positive bacteria, a protein or polysaccharide surface layer serves as the specific adhesin. (12 Dec 1998) |
| antibodies, bacterial | Immunoglobulins induced by substances elaborated by bacteria that have an antigenic activity. (12 Dec 1998) |
| antigens, bacterial | Substances elaborated by bacteria that have antigenic activity. (12 Dec 1998) |
| atypical bacterial forms | Microorganisms that have undergone greater changes than normal in morphology, physiology, or cultural characteristics. (12 Dec 1998) |
| bacteria-free stage of bacterial endocarditis | Endocarditis described prior to the antibiotic era and presumably due to spontaneous healing of the bacterial vegetations. (05 Mar 2000) |
| bacterial | <microbiology> Bacteria are group of micro-organisms that are a single cell approximately 1 micron in transverse diameter. Some bacteria cause disease in man, requiring treatment with an antibiotic. (27 Sep 1997) |
| bacterial adhesion | Physicochemical property of fimbriated (fimbriae, bacterial) and non-fimbriated bacteria of attaching to cells, tissue, and nonbiological surfaces. It is a factor in bacterial colonization and pathogenicity. (12 Dec 1998) |
| bacterial allergy | The concept that the atopic kind of type I allergic reactions may be caused by bacterial allergens, the delayed type of skin test, so-called because of its early association with bacterial antigens (e.g., the tuberculin test). (05 Mar 2000) |
| bacterial antagonism | The inhibition of one bacterium by products of another. (05 Mar 2000) |
| bacterial capsule | A layer of slime of variable composition which covers the surface of some bacteria; capsulated cells of pathogenic bacteria are usually more virulent than cells without capsules because the former are more resistant to phagocytic action. (05 Mar 2000) |
