[Structural Characteristics of Micro-nano Particle Size Biochar and Its Adsorption Mechanism for Cd].

The aim of this study was to investigate the structural characteristics of biochar with different micro/nano particle sizes and its effect on the adsorption performance of Cd. Corn stalk biochar with different particle sizes (180-250 μm, 50-75 μm, and ≤ 20 μm, denoted as BC-1, BC-2, and BC-3, respectively) were prepared using the sieving and ball milling method. The structural properties of different particle sizes of biochar were analyzed via elemental analysis, laser particle size analysis, SEM, BET, FTIR, and XPS.

Detoxification of Ochratoxin A by a novel Aspergillus oryzae strain and optimization of its biodegradation.

The mycotoxin Ochratoxin A (OTA) causes serious health risks and is found in food products throughout the world. The most promising method to detoxify this compound is biodegradation. In this study, Aspergillus oryzae strain M30011 was isolated and characterized based on its considerable capacity to degrade OTA.

[Effects of straw incorporation on rice carbon sequestration characteristics and grain yield formation].

A field experiment was conducted to study the effects of straw incorporation on rice dry matter accumulation and transportation, rice carbon sequestration and grain yield formation. The experiment included four levels of straw incorporation: 0 (control), 4000, 6000 and 8000 kg · hm(-2). Hybrid rice cultivar Zhongzheyou 1 was used in this experiment.
