Petroleum pollution is a severe environmental issue. Comprehensively revealing the genetic backgrounds of hydrocarbon-degrading microorganisms contributes to developing effective methods for bioremediation crude oil-polluted environments. Marine bacteriumc Achromobacter sp. HZ01 capable degrading hydrocarbons and producing biosurfactants. In this study, draft genome (5.53 Mb) strain was obtained by Illumina sequencing, containing 5,162 predicted genes. Genome annotation showed that "amino...
Abstract For more than one thousand years, Cordyceps sinensis has been revered as a unique halidom in the Qinghai-Tibetan Plateau for its mysterious life history and predominant medicinal values. This fungus-larva symbiote also attracted over-exploitation, while several problems on initial colonization of Ophiocordyceps host larva have constrained artificial cultivation. In this work, stable carbon isotope analysis was employed to analyse subsamples C . from 5 representative habitats. The...
Methane hydrate in the South China Sea (SCS) has extensively been considered to be biogenic on basis of its δ13C and δD values. Although previous efforts have greatly made, contribution thermogenic oil/gas still underestimated. In this study, biomarkers porewater geochemical parameters hydrate-free hydrate-bearing sediments Taixinan Basin, SCS measured for evaluating petroleum hydrocarbons formation deposits via a comparative study their source inputs organic matters, environmental...
The bacterial diseases of tilapia caused by Streptococcus agalactiae have resulted in the high mortality and huge economic loss industry. Matrix metalloproteinase-9 (MMP-9) may play an important role fighting infection. However, MMP-9 Nile against S. is still unclear. In this work, cDNA (NtMMP-9) has been cloned characterized. NtMMP-9 2043 bp encodes a putative protein 680 amino acids. contains conserved domains interacting with decorin inhibitors via binding forces compared to those other...
The temporal variation of sedimentary organic matters (SOM) in the East China Sea (ECS) is not fully assessed due to complicated natural and anthropogenic processes. In this study, compositions distributions multi-biomarker indicators (n-alkanes, n-alkanols specific sterols) a long sediment core collected from Min-Zhe fined-grained zone ECS were systematically studied reveal variations SOM sources phytoplankton records over last decades. results n-alkanes sterols have demonstrated that...
Humic substances in soil are considered to be an alternative food the tender plant roots for Thitarodes larvae habitats of Ophiocordyceps sinensis Qinghai-Tibetan Plateau. However, there is no report involving evaluation their potential as a source from composition and structure habitat soils. In this work, humic soils Sejila Mountain, Tibet were characterized by diverse techniques evaluating nutritional value possibility humus larvae. Fourier transform infrared spectroscopy revealed that...
Fe and Mn oxides (oxy)-hydroxides are the most abundant solid-phase electron acceptors in marine sediments, dissimilatory Fe/Mn reduction usually links with anaerobic oxidation of methane (AOM) organic matter (OMO) sediments. In this study, we report results from subsurface sediments Dongsha hydrate-bearing area South China Sea. The petrological geochemical signatures show that mediated by AOM OMO might occur above sulfate-methane transition zone. X-ray diffraction scanning microscopy...
Pullulan, which is a microbial exopolysaccharide, has found widespread applications in foods, biomedicines, and cosmetics. Despite its versatility, most wild-type strains tend to yield low levels of pullulan production, their mutants present genetic instability, achieving limited increase production. Therefore, mining new wild with robust pullulan-producing abilities remains an urgent concern. In this study, we novel strain, namely, Aureobasidium melanogenum ZH27, that had remarkable...
Biomarkers from methane hydrate-bearing sediments can provide vital evidence for microbial activities associated with methanogenesis and their relation to the formation of hydrates. However, former mainly focus on intact polar lipids these microorganisms, rarely investigate molecular hydrocarbons such as acyclic isoprenoids hopanes so far. In this work, composition biomarkers in cores SH2B SH7B Shenhu area, South China Sea (SCS) were identified by gas chromatography-mass spectrometry (GC-MS)...
Although various geochemical and geophysical investigations have already indicated a great resource potential in the Xisha area of South China Sea, origin organic matter molecular evidence for tracing migration hydrocarbons from deep petroleum reservoirs are still lacking. In this study, systematic analyses, including bulk parameters lipid biomarkers were performed sediments two cores. The C/N ratios δ13C δ15N values most samples, together with maxima short-chain n-alkanoic acids mid-chain...
