Microbes bacteria

Antibiotics are essentially natural compounds produced by microorganisms that are capable of inhibiting growth of pathogenic microbes, bacteria, and a few of the more simple microorganisms. [Pg.425]

Biocides are used to prevent the growth of microbes (bacteria, fungi) mainly in water-based latex paints. They are used for conservation of the binder and the paint during production and storage. These products also contain bacteria-degradable compounds like surfactants in an aqueous vehicle. Ammonia and volatile amines are used to stabilize the paint at a pH of 8-9. The water-soluble alkyd resin is solubilized... [Pg.665]

Biodiversity. Microbes (bacteria, fungi, protozoans, and viruses) represent half of the Earth s biomass. It is estimated that there are at least 10 million bacterial species alone, with only a few thousand described. Since the 1990 s, it has become clear that most microbes live in mixed communities with other microbes, with any given species present in a small number, none of which can be cultured in a laboratory. [Pg.208]

Pathogen Microbe (bacteria, virus, fungus, prion, parasite) that causes disease, especially in humans. [Pg.1646]

Pseudomonas. These gram-aegative bacteria are a diverse group of microbes that iahabit plants, water, and sod. Pseudomonads are metabohcaHy versatile, capable of carrying out chemical transformations, mineralization of organic compounds, and colonization on plant roots (16). The use of Pseudomonads strains ia the clean up of chemical wastes and od spills has drawn considerable attention. [Pg.248]

Bacillus sp. These bacteria are gram-positive soil microbes. Members of the Bacillus species supply 58% of iadustrial enzymes sold (19). Eor example, proteases from B. amjloliquefaciens and amylases from B. licheniformis glucose isomerase from B. coagulans are used ia a variety of iadustrial processes (see Enzyme applications-industrial). The proteiaaceous iaclusioas produced by B. thuringiensis are useful as iasect toxias. Thus exteasive fermentation technology has been developed for Bacillus species and low cost media are available (19). [Pg.248]

The main agents of these losses are the microbes and small animals, such as springtails and mites, that inhabit the soil. These feed on organic matter that contains carbon and nitrogen and produce carbon dioxide and ammonium ions as waste products. Other bacteria convert the ammonium to nitrate. Like most of us, these organisms are most active when the conditions suit them best, and their preferred options are warmth and moisture. In early autumn, the soil is still warm... [Pg.9]

No more than 5.0% samples total coliform-positive in a month, (For water systems that collect fewer than 40 routine samples per month, no more than one sample can be total coliform-positive). Every sample that has total coliforms must be analyzed for fecal coliforms. There may not be any fecal coliforms or E. coli. Fecal coliform and E. coli are bacteria whose presence indicates that the water may be contaminated with human or animal wastes. Disease-causing microbes (pathogens) in these wastes can cause diarrhea, cramps, nausea, headaches, or other symptoms. These pathogens may pose a special health risk for infants, young children, and people with severely compromised immune systems. [Pg.25]

Coliform bacteria Non-pathogenic microbes found in fecal matter that indicate the presence of water pollution are thereby a guide to the suitability for potable use. Colloids Very small, finely divided solids (particles that do not dissolve) that remain dispersed in a liquid for a long time due to their small size and electrical charge. [Pg.610]
