Anaerobic microbial activities such as sulfate reduction are important for the degradation of petroleum hydrocarbons (PHC) in contaminated aquifers.
The measured nitrate concentration reflects the sum of several microbial activities, such as ammonification, nitrification, denitrification, and formation of microbial biomass.
Climate warming may potentially stimulate microbial activities such as N mineralization, which could have cascading long-term effects on Arctic tundra ecosystems.
The term "incubator area" describes the hypothesis of Van Ness, whereby certain soil conditions may favour B. cereus sl vegetative growth in "hot spots" of microbial activities, such as the rhizosphere [ 26].
Compounds with enough evidence of their antimicrobial microbial activities such lupeol [ 33], betulinic acid [ 34], ursolic acid [ 35], β-sitosterol, sitosterol-3 O-β-D-glucopyranoside [ 36, 37], were not tested again in the present work.
Meena and Biswas (2014a), studying the effects of organic compost enrichment with phosphorus rocks, suggested that the significant increase of available P in soil is related to the production of organic acids by the microbial activity, such as citric acid, oxalic acid, and tartaric acid.
What Contaminants Could Be in Home Compost Piles "Contaminants in composting efforts are typically defined as those materials that either will not break down biologically, such as plastics, or that cause a decrease or elimination of the microbial activity, such as chemical compounds like pesticides," said Dr. Smith-Sebasto.
Taken together, this study and previous work show that the MeTCS fraction can become substantial in environments where TCS is readily degraded relative to MeTCS (such as at the air liquid interface of lakes) as well as in aerobic environments with high microbial activity (such as aerobic composters).
Differences in gene content across isolates account for differences in microbial functional activities, such as biofilm formation, pathogenic potential or antimicrobial resistance [ 12, 16- 19].
No relationship between specific phyla and obesity has been found in a more recent study, although significant associations between obesity and inferred microbial metabolic activities such as energy harvesting and osmolyte production (based on the presence of genes predicted to encode specific enzymatic activities) were found (Arumugam et al. 2011).
Microbial activity parameters, such as microbial basal respiration and nitrogen mineralization, showed an opposite pattern, suggesting that soil carbon in the conventional system (CONFYM) was more easily accessible to microorganisms than in organic systems.
