The transcription patterns of [FeFe]-hydrogenase genes (hydA), which encode the enzymes responsible for H2 production, were investigated during rice straw decomposition in paddy soil using molecular biological techniques. Paddy soil amended with and without rice straw was incubated under anoxic conditions. RNA was extracted from the soil, and three clone libraries of hydA were constructed using...

Herbicide residue analysis has gained importance worldwide, mainly for food quality control to minimize potentially adverse impacts on human health. A Gas chromatography-tandem mass spectrometry (GC-MS) method quantitative of acetochlor and s-metolachlor in maize soybean straw been developed, validated applied analyze the residues anilide herbicides. Straw material was dried, homogenized extrac...

Plant extraction is a thorough remediation method to remove heavy metals from soil. Chelating agents can enhance the effect of soil by plants. In this study, low molecular weight organic acids (LMWOAs), such as citric acid (CA), tartaric (TA) and polyaspartate (PASP), were added farmland contaminated with Cd Pb combined corn absorption Cadmium (Cd) Plumbum (Pb). The effects LMWOAs on growth yie...
