Hydrogen sulfide, a novel small molecule signalling agent, participates in GAs biosynthesis under heat stress and the regulation of multiple signaling pathway genes in Ganoderma lucidum

Project description:As one of the most important environmental factors, heat stress (HS) has been found to affect various biological activities of organisms such as growth, signal transmission, primary metabolism and secondary metabolism. Ganoderma lucidum has become a potential model system for evaluating how environmental factors regulate the secondary metabolism of basidiomycetes. Previous research showed that HS can induce the biosynthesis of ganoderic acids (GAs). In this study, we found the existence of hydrogen sulfide in Ganoderma lucidum; moreover, HS increased GAs biosynthesis and could affect the hydrogen sulfide content. We found that sodium hydrosulfide (NaHS), an exogenous donor of hydrogen sulfide, could revert the increased GAs biosynthesis elicited by HS. This result indicated that an increased content of hydrogen sulfide, within limits, was associated with HS-induced GAs biosynthesis. Our results further showed that the GAs content was increased in CBS-silenced strains and could be reverted to WT strain levels by the addition of NaHS. Transcriptomic analyses indicated that that H2S can affect various intracellular signal pathways and physiological processes in G. lucidum. Further studies showed that H2S could affect the intracellular calcium concentration and thus regulate the biosynthesis of GAs. This study demonstrated that hydrogen sulfide is involved in the regulation of secondary metabolic processes induced by heat stress in filamentous fungi.

Metagenomic, Proteomic and Metabolomic Investigations of Biodesulfurization-Competent Microorganisms

Project description:The increasing global human population has been associated with the development of high-density urban communities. This has led to increase in fossil energy consumption and posed serious threats to the environment and human health. Organosulfur compounds found in crude oil and transportation fuels such as diesel have gained strong attention because they are hazardous to human and the ecosystem. Moreover, the sulfur oxide gases resulting from fuel combustion are a major cause of acid rain. Governments and environmental organizations worldwide have recognized the problem and implemented strict regulations and legislations that limit the amount of sulfur in diesel. Hydrodesulphurization (HDS) is commonly used by oil refineries to reduce sulfur content in refined fuels. However, HDS has many disadvantages. It is costly, environmentally polluting, and not sufficiently efficient. Accordingly, there has been increasing interest in the development of alternative desulfurization technologies to circumvent the problems associated with the conventional HDS. Biodesulfurization (BDS) has emerged as an alternative or a complement technology to overcome the drawbacks of the conventional HDS. BDS exploits the ability of dedicated microorganisms to remove sulfur from many organosulfur compounds that are commonly found in crude oil and refined fuels. As compared to thermochemical treatments like HDS, BDS is environmentally friendly, cost-effective and active towards organosulfur compounds that escape the conventional HDS. Nonetheless, lack of deep understanding of the physiology and metabolism, particularly sulfur metabolism, of biodesulfurizing microbes has impeded the development and implementation of a commercially viable BDS process. In this project, we apply metabolomics and proteomics to better understand the physiological adaptations and sulfur metabolism of in a model biodesulfurization-competent strain Rhodococcus qingshengii IGTS8.

Changes in relative transcript amounts caused by hydrogen sulfide treatment, calprotectin treatment, and deletion of CstR in Staphylococcus Aureus

Project description:The Staphylococcus aureus strain Newman uses the dithiol-containing repressor CstR to sense sulfide stress via reactive sulfur species (RSS), allowing transcription of a mitochondrial-like sulfide oxidation system, the core of which is genetically linked to methicillin resistance determinants in MRSA strains. The cytoplasm maintains an excess of reduced relative to oxidized low molecular weight (LMW) thiols that are protective against oxidative stress and transition metal (Zn, Cd and Cu) toxicity, buffering these ions to low “free” concentrations via formation of coordination complexes. We hypothesize that unregulated H2S perturbs the LMW thiol pool by generating RSS; these, in turn, react with CstR cysteines (C31, C60), induce cst derepression, and are cleared by cst-encoded enzymes. These results show that sulfide stress induces the cst operon and a zinc starvation response, represses cysteine biosynthesis, and generally represses genes that are induced by acute oxidative stress; in addition, strong repression of the expression of staphylococcal virulence factors is observed in the ∆cstR strain.

Applying transcriptomics to screen the significantly altered genes, cell function and signal transduction pathway of chicken trachea exposured to hydrogen sulfide

Project description:Hydrogen sulfide (H2S) is well known to cause irritation and damage to airway following inhalation, but the mechanism by which H2S contributes to airway toxicity is unclear. We apply transcriptomics to demonstrate the possible effects, obtain valuable information about adverse health effects following H2S exposure and to study the molecular mechanisms of the gas toxicity in trachea.

Transcriptomic study of hydrogen sulfide toxicity in Methylococcus capsulatus

Project description:Stress response of Methylococcus capsulatus str.Bath toward hydrogen sulfide (H2S) was investigated via physiological study and transcriptomic profiling. M. capsulatus (Bath) can grow and tolerate up to 0.75%vol H2S in headspace. Vast change in pH suggests biological relevant sulfide oxidation. Dozens of H2S-sensitive genes were identified from comparison of cell transcriptome in different H2S concentrations. Mc sulfide quinone reductase (SQR) and persulfide dioxygenase were found to be active during sulfide detoxification. Moreover, xoxF, a novel lanthanide(Ln)-dependent methanol dehydrogenase (MDH) was overexpressed in H2S while mxaF, a calcium-dependent MDH, was down-regulated, and such MDH switch phenomenon is also well known to be induced by addition of lanthanide via an as-yet-unknown mechanism. Activities in quorum sensing and RND efflux pump also suggest their role in sulfide detoxification, and might provide insight on the xoxF/mxaF switch mechanism.
