| microbalance | A balance designed for use in weighing unusually small samples of materials. (05 Mar 2000) |
|---|---|
| microbe | <microbiology> A microscopic living organism, such as a bacteria, fungus, protozoa or virus. (09 Oct 1997) |
| microbenthos | <marine biology> Organisms (for example, protozoa, nematodes) living on or in aquatic substrates and too small to be seen with the naked eye. (29 Oct 1998) |
| microbial | <biology, microbiology> Pertaining to microorganisms too small to be seen with the naked eye. (29 Oct 1998) |
| microbial associates | Plant life. (09 Oct 1997) |
| microbial collagenase | <enzyme> A metalloproteinase which degrades helical regions of native collagen to small fragments. Preferred cleavage is -gly in the sequence -pro-xaa-gly-pro-. Six forms (or 2 classes) have been isolated from clostridium histolyticum that are immunologically cross-reactive but possess different sequences and different specificities. Other variants have been isolated from bacillus cereus, empedobacter collagenolyticum, pseudomonas marinoglutinosa, and species of vibrio and streptomyces. Registry number: EC 3.4.24.3 (12 Dec 1998) |
| microbial genetics | The study of hereditary mechanisms of microbes. (05 Mar 2000) |
| microbial herbicides | <biology, ecology, plant biology> Microorganisms that are toxic to specific plants or insects. Because of their narrow host range and limited toxicity, these microorganisms may be preferable to their chemical counterparts for certain pest control applications. (29 Oct 1998) |
| microbial mining | The use of microorganisms to remove minerals, particularly metals, from rocks. See: biohydrometallurgy, leaching. (14 Nov 1997) |
| microbial RNase II | <enzyme> An enzyme endonucleolytically cleaving RNA to 3'-nucleotides with 2',3'-cyclic nucleotides as intermediates. Synonym: Escherichia coli RNase I, microbial RNase II, plant RNase, RNase N2. (05 Mar 2000) |
| microbial sensitivity tests | Any tests that demonstrate the relative efficacy of different chemotherapeutic agents against specific microorganisms (i.e., bacteria, fungi, viruses). (12 Dec 1998) |
| microbial vitamin | A substance necessary for the growth of certain microorganisms, e.g., biotin, p-aminobenzoic acid. (05 Mar 2000) |
