Effect of Polystyrene Microplastics on Rice Seed Germination and Antioxidant Enzyme Activity

open access: yesToxics, 2021
The accumulation and distribution of microplastics (MPs) in agricultural soils, including rice fields, is well studied. However, only a few studies have investigated the uptake of MPs by rice plants and the consequential toxic effects of MPs under solid ...

Effects of different straw biochars on soil organic carbon, nitrogen, available phosphorus, and enzyme activity in paddy soil

open access: yesScientific Reports, 2020
Biochar is widely used as a soil amendment. Enzyme activity is an important factor that reflects soil metabolic activity, and is involved in biochemical processes such as organic matter decomposition and nutrient cycling in soils. However, the effects of

Linking microbial functional gene abundance and soil extracellular enzyme activity: Implications for soil carbon dynamics

open access: yesGlobal Change Biology, 2020
Recently advanced genome sequencing and annotation have enabled gene-level metabolic networks. However, it remains a major challenge to construct concrete links from microbial functional gene abundance to ecological processes. In this issue, Moore et al.

Methacrylated Chitosan Based UV Curable Support for Enzyme Immobilization [PDF]

open access: yesMaterials Research, 2017
UV curing is simple, fast and effective procedure for enzyme immobilization with minimized enzymatic activity. UV-curable methacrylated chitosan is here proposed as a support material for immobilization of lipase.

The effects of nitroxyl (HNO) on soluble guanylate cyclase activity: interactions at ferrous heme and cysteine thiols [PDF]

open access: yes, 2009
It has been previously proposed that nitric oxide (NO) is the only biologically relevant nitrogen oxide capable of activating the enzyme soluble guanylate cyclase (sGC). However, recent reports implicate HNO as another possible activator of sGC.
