Nonadditive Effects on Decomposition of a Mixture of Rice Straw and Groundnut Stover Applied to a Sandy Soil

open access: yesAgronomy, 2021
Rice straw is an abundant resource, but its use as a sandy soil amendment does not increase soil organic matter (SOM) accumulation. Our study aimed to determine the altered decomposition processes that result from mixing rice straw (RS) (low N, high ...

Active Microbial Sulfur Disproportionation in the Mesoproterozoic [PDF]

open access: yesScience, 2005
The environmental expression of sulfur compound disproportionation has been placed between 640 and 1050 million years ago (Ma) and linked to increases in atmospheric oxygen. These arguments have their basis in temporal changes in the magnitude of 34 S/ 32 S fractionations between sulfate and ...

Succession Patterns of Microbial Composition and Activity following the Diesel Spill in an Urban River

open access: yesMicroorganisms, 2023
Diesel spills in freshwater systems have adverse impacts on the water quality and the shore wetland. Microbial degradation is the major and ultimate natural mechanism that can clean the diesel from the environment.

Microbial Activity ̶ Indicators & Drivers

open access: yes, 2022
Biota des Kohlenstoffkreislaufs spielen bei der Speicherung und Verteilung des Kohlen-stoffs im Bodennahrungsnetz eine herausragende Rolle. Wobei der Abbau organischer Bodensubstanz stark von deren Verfügbarkeit für Mikroorganismen und Enzyme abhängt.

Imidazolinone Degradation in Soil in Response to Application History [PDF]

open access: yesPlanta Daninha, 2015
Accelerated herbicide degradation consists in its faster degradation in areas where it has been previously applied, due to the adaptation of microbial population to that particular compound.

Immunosuppressive activity of a microbial product

open access: yesFolia 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.

Early Effects of No-Till Use on Durum Wheat (Triticum durum Desf.): Productivity and Soil Functioning Vary between Two Contrasting Mediterranean Soils

open access: yesAgronomy, 2022
The diffusion of no-tillage (NT) is to be encouraged because of the benefits it can provide in terms of improving soil fertility and counteracting global warming and climate change as part of climate-smart agriculture practices. However, the introduction

Influence of interfaces on microbial activity

open access: yesMicrobiological Reviews, 1990
Bacterial adhesion in natural and artificial systems has been critically reviewed to investigate the influences exerted by the presence of interfaces. Numerous investigations have demonstrated that, in the presence of a solid phase, the activity of bacterial cultures is changed. Reviewing relevant literature, two problems were encountered. One is of an
