Litter microbial respiration and enzymatic resistance to drought stress

Elementa: Science of the Anthropocene, 2020
Many ecosystems are experiencing an increase in drought conditions as a consequence of climate warming and changing precipitation patterns. The stress imposed by these environmental changes can affect ecosystem processes such as the extracellular ...

The succession of bacterial and fungal communities during decomposition of two hygrophytes in a freshwater lake wetland

Ecosphere, 2020
The study of litter decomposition was often tightly linked to some hot topics such as global carbon balance and climate change, but the knowledge of microbes involved in litter decomposition remains limited especially in freshwater lake wetlands.

Extracellular enzyme stoichiometry reveals carbon and nitrogen limitations closely linked to bacterial communities in China’s largest saline lake

Frontiers in Microbiology, 2022
Saline lakes possess substantial carbon storage and play essential roles in global carbon cycling. Benthic microorganisms mine and decompose sediment organic matter via extracellular enzymes to acquire limiting nutrients and thus meet their element ...

Selection and probiotic characterization of exoenzyme-producing bacteria isolated from the gut of Catla catla (Actinopterygii: Cypriniformes: Cyprinidae) [PDF]

Acta Ichthyologica et Piscatoria, 2015
Background. Exoenzyme-producing gut microbiota and their likely use as probionts have been widely investigated in major carps. However, reports on exoenzyme-producing capacity together with inhibition of fish pathogens are scarce.

Contrasting responses of soil microbial biomass and extracellular enzyme activity along an elevation gradient on the eastern Qinghai-Tibetan Plateau

Frontiers in Microbiology, 2023
Soil microbial community composition and extracellular enzyme activity are two main drivers of biogeochemical cycling. Knowledge about their elevational patterns is of great importance for predicting ecosystem functioning in response to climate change ...

Extracellular Enzyme Activity and Its Implications for Organic Matter Cycling in Northern Chinese Marginal Seas

Frontiers in Microbiology, 2019
Extracellular enzymes, initiating the degradation of organic macromolecules, are important functional components of marine ecosystems. Measuring in situ seawater extracellular enzyme activity (EEA) can provide fundamental information for understanding ...

The use of phenyl-Sepharose for the affinity purification of proteinases [PDF]

, 1993
Phenyl-Sepharose is most often used as an adsorbent for hydrophobic interaction chromatography (HIC). We report on its effective use for the affinity purification of some extracellular thermostable proteinases from bacterial sources.

A Microbial‐Explicit Soil Organic Carbon Decomposition Model (MESDM): Development and Testing at a Semiarid Grassland Site

Journal of Advances in Modeling Earth Systems, 2022
Explicit representations of microbial processes in soil organic carbon (SOC) decomposition models have received increasing attention, because soil heterotrophic respiration remains one of the greatest uncertainties in climate‐carbon feedbacks projected ...

Inhibition of Extracellular Enzymes Exposed to Cyanopeptides

CHIMIA, 2020
Harmful cyanobacterial blooms in freshwater ecosystems produce bioactive secondary metabolites including cyanopeptides that pose ecological and human health risks. Only adverse effects of one class of cyanopeptides, microcystins, have been studied extensively and have consequently been included in water quality assessments.
