Control of microbes

Healthcare facilities, schools, hotels, residences, food storage areas, and manufacturing facilities such as electronics, food, pharmaceuticals, and other at-risk material production areas need to have a reaction plan for avoidance and control of airbone and surface sourced microbial contaminants. Strategies for control of microbes must exist for garments, beddings, linens, wipes, surgical fabrics, and other textiles used in healthcare operations and construction materials.

Because of its antimicrobial activity, acrolein has found use as an agent to control the growth of microbes in process feed lines, thereby controlling the rates of plugging and corrosion (see Wastes, industrial). 

Although many of the effects of microbes on metal are associated with growth this is not necessarily so because a biomass once established may cease to increase but continue its chemical activities often at an accelerated rate, once the controls on growth are relaxed. 

Dextran is the first microbial polysaccharide produced and utilized on an industrial scale. The potential importance of dextran as a structually (and property) controlled feedstock is clearly seen in light of the recent emphasis of molecular biologists and molecular engineers in the generation of microbes for feedstock production. Dextran is employed as pharmaceuticals (additives and coatings of medications), within cosmetics, as food extenders, as water-loss inhibitors in oilwell drilling muds and as the basis for a number of synthetic resins. 

The performance of a biotreatment system ultimately depends on optimization of the activity of microbes and the ability to control the process parameters of the treatment system [157]. In this respect, the ability to monitor gene copy numbers and gene expression is highly useful for real time optimization of the efficiency of a biotreatment system. Advanced molecular techniques as well as low cost methods (e.g., antibody detection of enzymes based on color reaction strips fluorescence i.e., GFP marked organisms with UV light detection) can also be applied to monitor the microbial community structure, persistence of the added bacteria, and their interactions with indigenous populations.

HeatTrodes can be used for bioventing air delivery or to deliver microbes, nutrients, or fluids for the control of moisture and pH levels. 

Why should microbes produce waste Many microbes, like plants, have considerable control over their intake of simple substances. Although many microbes do use complex molecules as a source of necessary elements, microbes commonly excrete degradative enzymes that breakdown the complex molecules into simpler substances, substances that can be taken up by the microbe in a controlled way. A characteristic of many microbes is their ability to alter their immediate environment and that includes their chemical environment. However, because of the diversity of microbes and their remarkably versatile biochemistry, one can never dismiss the possibility that some NPs made by microbes could serve a minor role in waste management .
