After demonstrating the presence of high levels of progesterone in the river sediment, we (Jenkins et al. 2003) hypothesized that some or all of the androgens in paper mill effluent and river sediment were generated by microbial degradation of phytosterols from the mill pulp.
Such a concentration in the water phase limits bacterial growth overall, since the fat portion of butter is generally safe from microbial degradation.
Modification of SWGA by galactosylation demonstrated that the glycosylation does not confer resistance to short peptides from microbial degradation.
Upon reaction of these S species with the biomass during early diagenesis, low amounts of S are able to preserve high amounts of OM from microbial degradation.
Soluble sugars can be protected from microbial degradation if the stalks are dried, which has already been shown [ 16, 23].
Presenting nature as a predictable and agreeable junior partner (or perhaps subcontractor), the report cheerfully explains that should a spill occur, "Currents and microbial degradation would remove the oil from the water column or dilute the constituents to background levels".
Increase in moisture reduction in consortium 2 was more due to temperature rise, resulting from increased microbial degradation activities.
Air sparging and soil vapor extraction (AS/SVE) are innovative remediation techniques that utilize volatilization and microbial degradation to remediate petroleum spills from soils and groundwater.
In addition, an increase in the OC/TN ratio in the middle of IS2 and IS3 sediments probably due to high amount of OC is being supplied from the microbial degradation of vegetation (Dittmar and Lara 2001).
To investigate functional genomic consequences of these differences, we compared their physiological levels of phytanic acid, a branched chain fatty acid that can be derived from the microbial degradation of chlorophyll in ruminant guts.
