Microbial decomposition is often highest at intermediate moisture levels, when soils are dry enough that oxygen availability is not limited but not so dry that microbes have insufficient access to water (Chapin et al., 2011a). Thus, post-fire changes in microbial decomposition may depend on the degree of soil drying following the fire.

title = "Microbial decomposition of soil organic matter is mediated by quality and quantity of crop residues: mechanisms and thresholds", abstract = "Crop residue quality and quantity have contrasting effects on soil organic matter (SOM) decomposition, but the mechanisms explaining such priming effect (PE) are still elusive.

Fungi are assumed to be important for boreal decomposition because of their enzymatic potential to decompose recalcitrant forms of soil C and their tolerance of the acidic pH values typical of most boreal soils (Hogberg€ et al. 2007). The decomposition of recalcitrant SOM was more sensitive to increased temperature in southern warm regions, which might attribute to the dominance of K‐selected microbial communities. It implies that climate warming would mobilize the larger recalcitrant pools in warm regions, exacerbating the positive feedback between increased MAT and CO 2 efflux.

2016-01-12 · With such complexity, it is relevant to compare microbial keratin decomposition with the microbial decomposition of well-studied polymers such as cellulose and chitin. Interestingly, it was recently shown that the specialized enzymes, lytic polysaccharide monoxygenases (LPMOs), shown to be important for breaking the recalcitrance of cellulose and chitin, are also found in keratin-degrading fungi.

By this stage, several  Decomposition and Nutrient Cycling. Decomposer invertebrate animals and microbes have quite distinct roles in breaking down organic detritus.

Microbial indicators such as Escherichia coli and fecal coliforms and the concentration of ammonia/ammonium were investigated in urine samples that were stored at 60 °C and 70 °C. Both the inactivation of indicators and decomposition of urea improved under storage temperatures of 60 °C and 70 °C compared with storage under ambient temperature.

2020-02-06 · Increasing the pH from ~3.5 to ~5.5 altered microbial community structure, however increases in CH4 production were non-significant. Contrary to expectations, N and P additions did not increase CO2 and CH4 production, indicating that nutrient availability was not a primary constraint in microbial decomposition of deep peat. Indole and its derivatives, including 3-methylindole and 4-chloroindole, are environmental pollutants that are present worldwide.
