ABSTRACT This study explored the effects of forest fires on soil microbial activity in soils classified by rock origin (igneous, metamorphic, and sedimentary) stratified subsoil depth (topsoil, subsoil). Microbial activity, indicated average well color development (AWCD) Shannon diversity indices, was higher undamaged topsoils compared to fire‐damaged ones. In contrast, subsoils, particularly metamorphic sedimentary soils, exhibited increased over time due organic matter decomposition. A...
This study was designed to investigate the effects of temperature and storage time on evolution bacterial communities in swine manure.Manure stored at -20°C, 4°C, 20°C, or 37°C sampled 7-day intervals over 28 days storage, for a total 5 points. To assess species present, 16S ribosomal RNA gene sequences were analyzed using pyrosequencing.After normalization, 113,934 sequence reads obtained, with an average length 466.6±4.4 bp. The diversity indices reduced as increased, slopes rarefaction...
Adipose tissue development and function play a critical role in the regulation of energy balance, lipid metabolism, pathophysiology metabolic syndromes. Although effect zinc ascorbate supplementation diabetes or glycemic control is known humans, underlying mechanism not well described. Here, we investigated zinc-chelated vitamin C (ZnC) compound on adipogenic differentiation 3T3-L1 preadipocytes. Treatment with ZnC for 8 d significantly promoted adipogenesis, which was characterized by...
The leachate generated by the decomposition of animal carcass has been implicated as an environmental contaminant surrounding burial site. High-throughput nucleotide sequencing was conducted to investigate bacterial communities in leachates from pig carcasses. We acquired 51,230 reads six different samples (1, 2, 3, 4, 6 and 14 week-old carcasses) found that sequences representing phylum Firmicutes predominated. diversity 16S rRNA gene highest at weeks, contrast those 2 weeks. relative...
Four Korea-native wild vegetables belonging to the Allium genus (Allium tuberosum Rottl., senescens L., thunbergii G. Don., and sacculiferum Maxim.) were investigated for their antioxidant anti-obesity potential, in order promote utilization of edible plants development potential new crops. In this study, we compared activity plant extracts by ABTS+ DPPH scavenging method. We then anti-adipogenic effects adipocytes. quantified phenolics using high-performance liquid chromatography (HPLC)...
CW-4Y was identified as Stenotrophomonas sp. by morphological and physiological characteristics, phylogenetic analysis of its 16S rDNA gene sequence. Nitrogen removal analyzed in relation to the ammonium concentration, presence organic carbon, carbon source, carbon-to-nitrogen ratio (C/N). has heterotrophic nitrification aerobic denitrification abilities. utilized only glucose sources, were observed regardless type nitrogen source. The maximum rate 80...
In this study, Arthrobacter scleromae SYE-3, which was isolated from indigenous plant in a subtropical region, Neigeria, with growth promoting activity evaluated to determine the optimal culture condition. A bacterial strain SYE-3 had IAA productivity (<TEX>$89.15{\pm}0.36mg/L$</TEX>) and ACC deaminase (<TEX>$0.20{\pm}0.06$</TEX> at 72 hours). Also, conditions such as temperature pH of were <TEX>$20^{\circ}C$</TEX> 10 LB medium, respectively. Strain up 3% salt tolerance medium. Plant ability...
To develop an enzyme-linked immunosorbent assay for the fungicide fenarimol, two synthesized haptens, haptens-1 and -2, purchased 4,4'-DDA were conjugated to carrier proteins (BSA, KLH, OVA). Polyclonal antibodies raised against hapten-1,2−KLH conjugates in rabbits coating antigens of hapten-1,2−BSA conjugates, hapten-2−OVA conjugate, 4,4'-DDA−BSA conjugate screened selected homologous and/or heterologous ELISA formats. Two competitive indirect ELISAs selected: assays I II. The optimized...
A competitive indirect enzyme-linked immunosorbent assay was developed for the fungicide iprovalicarb, using a polyclonal antibody produced against hapten conjugated through carboxyl group on benzene ring to keyhole limpet hemocyanin. Under an optimized condition heterologous format, IC(50) of 3.51 ng/mL and lowest detection limit 0.065 were obtained. When isopropoxy removed from iprovalicarb structure synthesis hapten, resulting not successful as immunogen, indicating that isopropyl moiety...
Soil microbial community analysis of farmland soil sprayed with lye in order to use fertilizer Nigeria was performed. As a control, two kinds soils not lye, located Eungo and Lagos general practice agriculture selected. pH 8.25 through alkalization reaction, while the other samples were 6.22 5.94. Substrate utilization species diversity index low than that Biolog ecoplate. result principal component analysis, relationship between three low. Microbial performed by DGGE most them uncultured...
