The PeroxiBase (http://peroxibase.toulouse.inra.fr/) is a specialized database devoted to peroxidases' families, which are major actors of stress responses. In addition the increasing number sequences and complete modification Web interface, new analysis tools functionalities have been developed since previous publication in NAR issue. Nucleotide graphical representation gene structure can now be included for entries containing genomic cross-references. An expert semi-automatic annotation...

Abstract In this study, we investigated the codon bias of twelve mitochondrial core protein coding genes (PCGs) in eight Pleurotus strains, two which are from same species. The results revealed that codons all strains had a preference for ending A/T. Furthermore, correlation between base compositions and adaptation index (CAI), (CBI) frequency optimal (FOP) indices was also detected, implying influence composition on bias. P. ostreatus species were found to have differences various...

Abstract Background Activated sludge (AS) systems in wastewater treatment plants (WWTPs) harbor enormous viruses that regulate microbial metabolism and nutrient cycling, significantly influencing the stability of AS systems. However, our knowledge about diversity viral taxonomic groups functional traits global is still limited. To address this gap, we investigated biogeography DNA communities using 85,114 operational units (vOTUs) recovered from 144 samples collected across 54 WWTPs 13...

Abstract Purpose: Recent studies indicated that RUNX3 exhibits potent antitumor activity. However, the underlying molecular mechanisms of this activity remain unclear. In present study, we used a gastric cancer model to determine effect expression on tumor angiogenesis. Experimental Design: The effects increased vascular endothelial growth factor (VEGF) in and angiogenic potential human cells were determined vitro animal models. VEGF was 120 specimens their relationship analyzed. Results:...

Methanogenic communities that degrade alkanes have been reported. However, little is known about the key players involved in process. hexadecane-degrading consortia were enriched from an oilfield (Shengli, China). The microbial dynamics during transfer incubations monitored using terminal restriction fragment length polymorphism (T-RFLP) fingerprinting of 16S rRNA genes combination with cloning and sequencing. archaeal community shifted a predominance aceticlastic Methanosaeta early...

Silver nanoparticles (AgNPs) were rapidly synthesized using an exopolysaccharide from Arthrobacter sp. B4 (B4-EPS). The optimum condition for AgNPs synthesis was under the concentration of 5 g/L B4-EPS and 1 mM AgNO 3 at 80°C between pH 7.0 8.0. resulting displayed a face-centred-cubic structure with size range 9 nm to 72 nm. Further analysis showed that flocculation reduction played pivotal role in formation AgNPs. Furthermore, these exhibited great stability, excellent antimicrobial...

The novel exopolysaccharide HZ-7 is produced by Klebsiella sp. H-207, and its fermentation conditions were optimized response surface methodology (RSM). In this study, the medium consisted of sucrose 31.93 g/L, KNO(3) 2.17 g/L K(2)HPO(4) 5.47 g/L; while culture seed age 13 h, with an inoculum size 10.6% incubation temperature 28.9°C. A maximum yield about 15.05 was achieved under using RSM single-factor experiments. Next partially purified characterized. resulting product showed good...

In the present study, two mitogenomes from Filobasidium genus were assembled and compared with other Tremellomycetes mitogenomes. The of F. wieringae globisporum both comprised circular DNA molecules, sizes 27,861 bp 71,783 bp, respectively. Comparative mitogenomic analysis revealed that genetic contents, tRNAs, codon usages species differed greatly. varied greatly introns being main factor contributing to mitogenome expansion in globisporum. Positive selection was observed several...
