Fermented chili products are popular traditional fermented foods around the world. However， differences in microbial communities in fermented chilies from different regions and how they affect the flavor compounds in chili fermentation have not been reported. In this study， the dynamics of flavor compounds and microbial communities in fermented chilies from Sichuan， Guizhou， and Hunan were systematically investigated by macro-genome sequencing， solid phase microextraction-gas chromatograph-mass spectrometry (SPmE-GC-mS)， electronic nose， and electronic tongue techniques. Simultaneously， the microbial metabolic mechanisms and the relationship between flavor compounds and microbiome were unraveled through staged and simulated fermentation analysis. The results showed that 53 chemical odorants， including alcohols， esters， aldehydes， and acids， were identified as chemical markers to differentiate the regional samples. Twelve microbial species， including Staphylococcus xylosus， Unclassified staphylococcus species， Weissella confusus， Lactococcus cremoris， Lactococcus garvieae， Lactiplantibacillus sakei， Pediciococcus propionicigenes， Pediciococcus idahonensis， Pediciococcus aciditolerans， Nocardioides antri， Debaryomyces hansenii， and Colletotrichum scovillei， were identified as microbial markers to differentiate the regional samples. Correlation analysis showed that Lactobacillaceae was associated with fruity， floral， spicy， and fatty aromas. The electronic nose and tongue analysis results showed that 9 flavor and 8 taste indicators significantly differed between regional samples (P mpounds and microbial diversity were robust under initial selection stress and showed higher diversity under metabolome-microbiome interactions. Importantly， simulated fermentation confirmed that metabolome-microbiome interactions drove the shift in microbial structure， metabolism， and flavor in regionally fermented chilies. These results provide insights into

many nanoparticles have been created over the last few decades using a variety of techniques and used to develop environmental technology, including water treatment, the detection of persistent contaminants, and soil and water remediation. The studies of alternative inputs for nanoparticle production as well as the use of green synthesis techniques are driven by the field of materials science and engineering’s growing interest in increasing the sustainability of the processes involved in their production. In this paper, we begin by providing an overview of the fundamental principles of producing nanoparticles from different sources, such as plastic, electronic, metal, and industrial waste. We elaborate on key facts of waste identification as a workable input for the treatment and recovery of metal and carbon-based nanoparticles. We next go over several controlling factors that play a role in creating nanoparticles, pointing out probable conclusions as we go. Then, we show some instances of waste-derived nanoparticles used in a proof-of-concept experiment of technology for applications in water quality and safety. Before scaling up production and implementing waste-derived nanoparticles, there are several present problems from the toxicological and life-cycle perspectives that must be taken into account.
