Dynamics of the Bacterial Community's Soil During the In-Situ Degradation Process of Waste Chicken Feathers.

Unlabelled: Bacteria play an important role in the biodegradation of feather waste. The exploration of the related microbial community structure and diversity is essential to improve the performance of feather waste treatment processes. In the present work, an in-situ soil sampled from a poultry farm was directly used to simulate and accelerate the natural degradation processes of feather waste under laboratory conditions, in which the dynamics of the microbial communities was further analyzed by Illumina HiSeq high-throughput 16S rRNA gene sequencing.

Antifungal Action of Antifungalmycin N2 Against Rhizoctonia solani by Disrupting Cell Membrane and Inhibiting Succinate Dehydrogenase.

Antifungalmycin N2 (3-methyl-3,5-amino-4-vinyl-2-pyrone, CHON) was a novel structural antifungal metabolite produced by Streptomyces sp. strain N2. Our previous study reported that the antagonistic interaction between antifungalmycin N2 and Rhizoctonia solani was accompanied by an oxidative stress in R.

Antagonistic activity and mechanism of an isolated Streptomyces corchorusii stain AUH-1 against phytopathogenic fungi.

The various diseases that occur during the growth of plants usually cause a significant reduction in production and quality of agricultural products. Actinomycetes, especially Streptomyces spp., become a valuable biological control resource due to their preponderant abilities to produce various secondary metabolites with novel structure and remarkable biological activity.

[Effects of temperature and pH on digestive enzymes activities in Whitmania pigra].

Objective: Current study was conducted to investigate and compare the impact of temperature and pH on the activities of amylase, protease and lipase in alimentary tract of Whitmania pigra.

Method: The responses of amylase, protease, and lipase activities were determined over a wide range of temperatures (7-52 degrees C) and pH gradient (2.2-11.
