“…6). FMN reductase can act as an electron transporter that can transfer electrons from the substrate to the electron acceptor [35]. The quinone oxidoreductase ChrR encoded by the chrR gene has been demonstrated to possess chromate reductase activity [36], therefore the quinone oxidoreductase QOR may have similar functionality.…”

Cellulomonas fimi Clb-11 can reduce high toxic Cr (VI) to low toxic Cr (III). In this study, transcriptomics was used to analyze the key genes, which was involved in Cr (VI) uptake and reduction in C. fimi Clb-11. The results showed that when C. fimi Clb-11 was subjected to 0.5 mM Cr (VI) stress, 654 genes were upregulated. Among them, phosphate transport protein encoding gene phoU, inorganic phosphate transport protein encoding gene TC.PIT, and molybdate transport protein encoding genes modA, modB, and modC were involved in the passive uptake of Cr (VI) by C. fimi Clb-11. Cytochrome c subunits encoding genes qcrA and qcrC, as well as cytochrome c oxidase subunits encoding genes coxB and coxC were involved in the intracellular reduction of Cr (VI) by C. fimi Clb-11. Additionally, several unreported genes were found to be upregulated in C. fimi Clb-11 under Cr (VI) stress. Manganese transport protein encoding gene mntH and nickel transport system permease encoding genes ABC.PE.P and ABC.PE.P1 may participate in the passive uptake of Cr (VI) by C. fimi Clb-11. Osmoprotectant transport system ATP-binding protein encoding gene opuA, osmoprotectant transport system substrate-binding protein encoding gene opuC, and osmoprotectant transport system permease encoding gene opuBD may be crucial for maintaining intracellular water content in cells and enhancing the resistance of C. fimi Clb-11 to Cr (VI). Proton pump subunit encoding genes atpA, atpB, atpE, atpF, and atpH, as well as sodium-hydrogen antiporter subunit encoding genes mnhA and mnhC, may be involved in the extracellular proton secretion to reduce Cr (VI) in extracellular. Iron complex transport system substrate-binding protein encoding gene ABC.FEV.S, vacuolar iron transporter encoding gene VIT, FMN reductase gene encoding gene ssuE, and quinone oxidoreductase QOR encoding genes qor and qorB may participate in the intracellular reduction of Cr (VI) by C. fimi Clb-11. The pyruvate dehydrogenase encoding genes pdhA, pdhB, and pdhC, as well as the succinate dehydrogenase encoding genes sdhA, sdhB, and sdhD, may play important roles in supplying electrons for C. fimi Clb-11 to reduce Cr (VI). Our study provides theoretical references for optimizing microbial Cr (VI) resistance and microbial chromium pollution remediation techniques.

The bibliometric method was used in this study to analyze current advances in the anaerobic digestion (AD) of cellulose waste. The result shows that the number of articles increased rapidly after 2010, suggesting a growing interest in this field. The USA and China were the top two countries with the highest number of published articles. AD of cellulose waste is being actively explored in many countries, and partnerships between countries are being actively formed. The top three subject categories were Environmental Sciences & Ecology, Engineering, Energy & Fuels. The most widely published and influential journals were Bioresource Technology, Water Science and Technology, and Waste Management. The co-occurrence and trend analysis of author keywords indicates that current research is primarily focused on pretreatment and co-digestion. Microbial community analysis plays a crucial role in elucidating the mechanisms, and life cycle analysis (LCA) could evaluate the impact on the environment at different stages. Microbial community analysis and LCA will be the hotspots in the future. To some extent, this study helps to understand the current global status and trends of the related research.

“…A strong relationship between mushroom species and their biotechnological attributes has been reported in the literature. Various studies have provided insights into various fields, including the production of enzymes such as cellulase [20], sugar alcohols such as arabitol, erythritol, and mannitol [21], and the processes that lead to the production of biofuels or the use of bioenergy [24][25][26]. Hence, it could conceivably be hypothesized that mushrooms have a crucial role to play in the production of food and energy and that there is a strong relationship between mushrooms and the water-energy-food nexus.…”

Mushrooms have always been an important source of food, with high nutritional value and medicinal attributes. With the use of biotechnological applications, mushrooms have gained further attention as a source of healthy food and bioenergy. This review presents different biotechnological applications and explores how these can support global food, energy, and water security. It highlights mushroom’s relevance to meet the sustainable development goals of the UN. This review also discusses mushroom farming and its requirements. The biotechnology review includes sections on how to use mushrooms in producing nanoparticles, bioenergy, and bioactive compounds, as well as how to use mushrooms in bioremediation. The different applications are discussed under the water, energy, and food (WEF) nexus. As far as we know, this is the first report on mushroom biotechnology and its relationships to the WEF nexus. Finally, the review valorizes mushroom biotechnology and suggests different possibilities for mushroom farming integration.
