Microbial activity in the landfill soil

Applied Biochemistry and Microbiology, 2012
The research objective was to determine the activity of microorganisms in the soil exposed to direct influence of a landfill, as well as in the soil beyond its influence. Fluorescein diacetate (FDA) hydrolytic activity and respiration in the soil were determined. The highest number of cultivated bacteria was recorded at the site located within the zone

Immunosuppressive activity of a microbial product

Folia Pharmacologica Japonica, 1997
Microbial products have amazing diversity and complexity in their chemical structures as well as in their biological activities. The successful discovery and development of FK506 (Tacrolimus) adds a new example showing that microbial products are agents with potential therapeutic benefits.

Harnessing microbial activities for environmental cleanup

Current Opinion in Biotechnology, 2006
Human 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 ...

Microbial activity in soil

Current Opinion in Biotechnology, 1993
Abstract Soils are heterogeneous matrices with complex physical and chemical characteristics. A variety of constraints are placed upon the metabolic potential of soil microorganisms, including the finite growth space which is compounded by restricted opportunities to migrate, limited accessibility to substrate and electron acceptors, and extreme ...

Microbial production of sensory-active miraculin

Biochemical and Biophysical Research Communications, 2007
Miraculin (MCL), a tropical fruit protein, is unique in that it has taste-modifying activity to convert sourness to sweetness, though flat in taste at neutral pH. To obtain a sufficient amount of MCL to examine the mechanism involved in this sensory event at the molecular level, we transformed Aspergillus oryzae by introducing the MCL gene ...

Seasonal change of microbial activity in microbially aided bioremediation

Journal of Geochemical Exploration, 2017
Abstract Microbial community patterns and their potential substrate utilization were examined to test for sustainability in metal polluted soil. The acid mine drainage (AMD) influenced test field was characterized for total soil respiration and the functional diversity of the soil bacterial communities using BIOLOG EcoPlate assays.

Stability of soil microbial structure and activity depends on microbial diversity

Environmental Microbiology Reports, 2013
Summary Despite the central role of microbes in soil processes, empirical evidence concerning the effect of their diversity on soil stability remains controversial. Here, we addressed the ecological insurance hypothesis by examining the stability of microbial communities along a gradient of soil microbial diversity in response to ...

Microbial fuel cell biosensor for in situ assessment of microbial activity

Biosensors and Bioelectronics, 2008
Microbial fuel cell (MFC)-based sensing was explored to provide useful information for the development of an approach to in situ monitoring of substrate concentration and microbial respiration rate. The ability of a MFC to provide meaningful information about in situ microbial respiration and analyte concentration was examined in column systems, where ...

Pharmacologically Active Compounds from Microbial Origin

1977
Publisher Summary This chapter discusses the pharmacologically active compounds from microbial origin. As microorganisms provide such a wide variety of metabolic metabolites, it would seem reasonable to assume that microbial metabolites would be excellent sources of pharmacological compounds.

Activity assessment of microbial fibrinolytic enzymes

Applied Microbiology and Biotechnology, 2013
Conversion 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.
