It provides an overview of the fundamentals of MSW and the basic aspects of nitrogen and sulfur elements.

The analysis indicates that the complete scenario of the occurrence form of sulfur and nitrogen elements in MSW is difficult to obtain, owing to the diverse sources and complicated compositions. However, with the assistance of advanced characterization and quantification methods (XPS, XRD, TG-FTIR, et al.), the common sulfur- and nitrogen-containing compounds in both organic and inorganic states can be detected. Adjustment of gasification conditions can regulate the transformation of these elements for emission control. The multiple pollutants including H₂S, SO<em>_x</em>, COS, NH₃, HCN and NO<em>_x</em> cannot be eliminated by one-step treatment but a combination of adsorption and catalytic treatments may realize the control goal. This research aims to benefit meeting emission standards during MSW gasification and to provide a reference for other processes such as incineration, pyrolysis and other feedstocks like biomass and refuse derived fuel (RDF).</p></div>","PeriodicalId":52958,"journal":{"name":"Carbon Resources Conversion","volume":"6 3","pages":"Pages 184-204"},"PeriodicalIF":6.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49508040","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Then, <em>Pleurotus</em> spp. were cultivated on the most promising substrates and essential cultivation aspects (earliness, total mushroom yield, biological efficiency-BE) and carposomes’ quality parameters (weight, morphological characteristics) were evaluated. Laccase and endoglucanase production by <em>Pleurotus</em> species were also determined at 50 and 100% of colonization stages. All species showed their fastest mycelial growth rate (up to 5 mm/day) on substrates consisted of SMC, whereas many combinations of species/substrate enhanced biomass production. The SMS GZ supplementation positively affected laccase activity; in the cultures of <em>P. ostreatus</em> and <em>P. eryngii</em> the highest values were 62,539 and 17,584 U/g d.w., respectively. On the contrary, small amounts of endoglucanase were produced (0.007 to 0.322 U/g d.w.); the greatest production was recorded for <em>P. ostreatus</em> at full colonization. Regarding fermentation in bags, significant amount of total mushroom yield was produced in all substrates and those with SMS GZ supported the fastest earliness period and the highest BE for both <em>Pleurotus</em> species. BE values ranged from 54 to 133% for <em>P. ostreatus</em> and from 53 to 121% for <em>P. eryngii</em>.

SCP is produced by a plethora of microorganisms, including fungi, yeasts, bacteria, and algae while many of them are Generally Recognized as Safe (GRAS). Selected microbial strains present satisfying growth capability with high yields when cultivated in renewable feedstock.
