Abstract The objective of this work was to identify microbial communities associated with the surfaces alkali feldspars and determine whether these microbes might be involved in weathering rocks for agronomic benefit. Samples were taken from profiles soils developed on a syenite, considered as raw material agromineral production, located municipality Triunfo, state Pernambuco, Brazil. Molecular...
Arthrobacter nitroguajacolicus Rü61a, which utilizes quinaldine as sole source of carbon and energy, was shown to contain a conjugative linear plasmid of approximately 110 kb, named pAL1. It exhibits similarities with other linear plasmids from Actinomycetales in that it has proteins covalently attached to its 5' ends. Southern hybridization with probes for the genes encoding quinaldine 4-oxida...
This study evaluated the effect of probiotics (Clostridium butyricum, Bacillus coagulans) and Chinese herb polysaccharides (Astragalus polysaccharides, APS) on growth performance, immunity, disease resistance, intestinal microbiota rainbow trout (Oncorhynchus mykiss). Specimens O. mykiss (n = 360; 79.9 ± 2.2 g) were fed for 42 days with different diets containing a basal diet (control, C0), sup...
Many bacteria and actinomycetales use L-cysteine biosynthesis to increase their tolerance antibacterial treatment establish a long-lasting infection. In turn, this might lead the onset of antimicrobial resistance that currently represents one most menacing threats public health worldwide. The biosynthetic machinery required synthesise is absent in mammals; therefore, its exploitation as drug ta...
BACKGROUND The human stomach, when healthy, is not a suitable host for microorganisms, but in pathological conditions such as gastritis, when gastric acid secretion is impaired, microbial overgrowth can be observed. Apart from Helicobacter pylori, the composition of microbiota, resident or exogenously introduced during neutral/high pH conditions, has not been investigated thoroughly. Thus, it i...
Soil microbial diversity represents the largest global reservoir of novel microorganisms and enzymes. In this study, we coupled functional metagenomics and DNA stable-isotope probing (DNA-SIP) using multiple plant-derived carbon substrates and diverse soils to characterize active soil bacterial communities and their glycoside hydrolase genes, which have value for industrial applications. We inc...
