Waksman's classification are laid down on a broad morphologic basis, whereas the species determinations are more largely dependent upon physiologic behavior. The erection of the ordinal group, the Actinomycetales intermediate and distinct from the Eubacteriales and the Eumycetes, reflect the author's feeling that this is a heterogeneous assemblage of organisms which are perhaps not too closely ...

Tyrosinases (monophenol, o-diphenol:oxygen oxidoreductase, EC (1.14.18.1) are copper-containg enzymes which catalyze the o-hydroxylation of monophenols and subsequent oxidation of o-diphenols to quinones. The enzymes are involved in the pigmentation and are important factors in wound healing and primary immune response. Tyrosinases are found in prokaryotic and eukaryotic microorganisms, in mamm...

Changes in the microbial populations in the conjunctival sacs of animals have traditionally been evaluated using conventional microbiology techniques. The goal of this study was to examine the suitability of a methodology which may reveal a previously unknown microbiome inhabiting feline conjunctival membranes. In the present study, we determined the microbial diversity in feline conjunctivas b...

Recent studies in the Parkinson's literature have cited a tuberculosis-like germ called Nocardia as being responsible for Parkinson's disease. Kohbata seemingly cemented a relationship between Nocardia and Parkinson's by finding serologic evidence in 20 of 20 Parkinson's patients, acknowledging that blood tests for Nocardia and the mycobacteria such as tuberculosis often cross-react, as they be...

水体垂向分层是深水湖泊一个重要的特征，这不仅影响水体理化环境因子，而且影响水生生物组成的垂向分布，但是对不同水层水体细菌的多样性和群落结构组成的形成与维持机制知之甚少. 本研究以抚仙湖为研究对象，在水体热力分层期间采集不同位点、不同水层水样，借助16S rDNA Illumina Miseq高通量测序技术，探究水体细菌多样性和群落结构组成的空间分布特征及关键影响因子. 研究结果表明：(1)抚仙湖北部湖心在水深15~40 m处出现温跃层，温度由23℃降至15℃，其余理化环境因子也存在明显的垂向分层现象；与垂向差异相比，表层水体各理化因子在水平方向上的差异相对较小. (2)在水平方向上，南部湖心表层水体细菌alpha多样性(Operational Taxonomic Unit数目和Faith's phylogenetic diversity)最高；在垂向上，水体细菌alpha多样性随着采...

Microbes that colonize pyrogenic organic matter (PyOM) (also called biochar) play an important role in PyOM mineralization and crucially affect soil biogeochemical cycling, while the microbial community composition associated with PyOM particles is poorly understood. We generated two manure-based PyOMs with different characteristics (PyOM pyrolyzed at the low temperature of 300°C [i.e., PyOM300...
