Effect of chlorpyrifos on soil microbial activity
Environmental Toxicology and Chemistry, 1995AbstractA study of the effects of the insecticide chlorpyrifos on soil microbial activity was made. Parameters included total bacterial populations, fungi, aerobic N2-fixing bacteria, denitrifying bacteria, nitrifying bacteria, nitrogenase activity, acid and alkaline phosphatases, arylsulfatase, and dehydrogenase.

Activation of latent collagenase by microbial plaque
Journal of Periodontal Research, 1974Sterile extracts of whole human microbial plaque released substantial latent collagenolytic activity in gingival collagenase preparations, homogenates of polymorphonuclear leukocytes, and tissue macrophages. The plaque activation factor was thermolabile, nondialyzable, and had essentially no inherent collagenolytic activity.

EFFECTS OF MICROBIAL ACTIVITY ON AQUATIC POLLUTANTS*
Annals of the New York Academy of Sciences, 1977Bacteria and fungi present in estuarine and marine water and sediment accomplish significant degradation of crude oil, refined oils, polychlorinated biphenyls, and organomercurials, with the rate and extent of degradation varying with species, geographic source, temperature, and other biologic and environmental parameters.

Microbial Activity in Activated Carbon Filters
Journal of the Environmental Engineering Division, 1982To obtain information on the adsorption, bacteriological oxidation and desorption processes in filters, the oxygen consumption (Δ\NO\d2) and the removal of organic carbon (Δ\NTOC) as well as their relation to one another (Δ\NC/Δ\NO\d2) were studied.

Harnessing microbial activities for environmental cleanup
Current Opinion in Biotechnology, 2006Human activities have released large amounts of toxic organic and inorganic chemicals into the environment. Toxic waste streams threaten dwindling drinking water supplies and impact terrestrial, estuarine and marine ecosystems. Cleanup is technically challenging and the costs based on traditional technologies are exceeding the economic capabilities of ...

Tailoring Activity and Selectivity of Microbial Transglutaminase
2019Microbial transglutaminase (mTG), a protein-glutamine γ-glutamyltransferase from Streptomyces mobaraensis, is an enzyme capable of forming isopeptide bonds between the nearly inert (from the chemical point of view) γ-carboxamides present in the side chain of glutamine residues and primary amines.

Activity assessment of microbial fibrinolytic enzymes
Applied Microbiology and Biotechnology, 2013Conversion of fibrinogen to fibrin inside blood vessels results in thrombosis, leading to myocardial infarction and other cardiovascular diseases. In general, there are four therapy options: surgical operation, intake of antiplatelets, anticoagulants, or fibrinolytic enzymes.

Microbial Society and its Activity in the Soil
Zentralblatt für Bakteriologie, Parasitenkunde, Infektionskrankheiten und Hygiene. Zweite Naturwissenschaftliche Abteilung: Allgemeine, Landwirtschaftliche und Technische Mikrobiologie, 1977In this study, with the help of the buried slide method, a qualitative observation of the microsociological association in the soil was assessed. Fungal mycelium cohabiting with bacterial forms, rods as well as cocci, individual colonies of Azotobacter-type cells, and certain algae of Hantzschia species were recorded in a central European typical ...
