It finds applications in the synthesis of acrylic acid, 1,3-propanediol, and other derivatives, positioning it as a potential cornerstone for bio-based plastics. This review consolidates the latest breakthroughs in microbial 3-HP production, encompassing advanced strain engineering, pathway rewiring, cofactor optimization, metabolic modeling, and flux balance analysis.

This study investigated the decolorization efficacy and adsorption behavior of spent mushroom substrate (SMS) and its aqueous extract (SMS-T) toward ten synthetic dyes, both before and after thermal treatment. SMS achieved total decolorization rates of 72.65-97.84% across the tested dyes. Adsorption by the SMS matrix accounted for only 0.68-36.46% of decolorization for Bromophenol Blue, Malachite Green, Methylene Blue, Rose Bengal, and Remazol Brilliant Blue R, substantially lower than the differential removal (8.25-71.63%) between SMS and SMS-T. This indicates the existence of a non-adsorptive decolorization mechanism mediated by water-insoluble SMS components. Comparative analysis of SMS-T before and after heat treatment revealed that thermally processed SMS-T maintained > 30% decolorization efficiency for Methylene Blue, Brilliant Blue G, and Crystal Violet. Notably, decolorization rates for Rose Bengal and Remazol Brilliant Blue R showed no significant difference post-treatment, demonstrating the presence of heat-stable non-enzymatic decolorization mechanisms in SMS-T. Isothermal adsorption studies indicated that the Langmuir model optimally described SMS adsorption for Congo Red, Aniline Blue, Malachite Green, and Remazol Brilliant Blue R. In contrast, the Freundlich model better fitted the other six dyes. Concurrently, SMS achieved effective decolorization and partial toxicity reduction when treating simulated textile effluent (STE). This work proposes two complementary mechanisms governing SMS-mediated decolorization: non-adsorptive decolorization by water-insoluble SMS fractions and heat-resilient non-enzymatic pathways in SMS-T.

In the present work, a novel genome exponential amplification reaction (GEAR) based detection assay was developed for Salmonella by amplifying the invA gene. The inclusive and exclusive specificity of the test was verified to be 100% employing reference strains of Salmonella and other non-target pathogenic bacteria. The reaction sensitivity of the GEAR was determined to be 32.4 fg/µL or fg/reaction, making it 100 times more sensitive than conventional molecular techniques such as PCR and real-time PCR. The method sensitivity of the developed GEAR test was evaluated using experimentally contaminated pork samples, showing a detection limit of 212 CFU/g for culture independent direct detection and 2.12 CFU/g when combined with 6 h of enrichment. The assay was further validated on 140 real-world pork samples and was evaluated alongside real-time PCR and culture methods.

This study investigates the effect of caffeine, a food additive that induces cytochrome P450 (P450), on the production of crude triterpenoids and biomass of G. multipileum-the experimental procedure involved adding caffeine and Limonene to the basal culture at different concentrations and times. When 0.4% caffeine was added on the 6th day, the triterpenoid content reached 53.72mg/g DW on the 15th day, which was 8.4 times that of the control. In addition, total polyphenol content also increased, reaching 1.96mg/g DW (74% higher than control), suggesting that caffeine exerts a broader metabolic influence beyond triterpenoid synthesis. This suggests that caffeine, acting as a P450 inducer, likely enhances the activity and abundance of triterpenoid synthase in G. multipileum, contributing to the observed increase in triterpenoid production. Continuing the experiment, when 1% (v/v) Limonene was added on the 6th day, the triterpenoid and total polyphenol contents reached 66.60mg/g DW and 3.72mg/g DW, respectively, on the 15th day, which were 10.4 times and 3.3 times that of the control. This finding indicates that when caffeine induces the production of more triterpene synthase, additional precursors are required, and thus, the addition of limonene enhances triterpenoid production. This study demonstrates that significant increases in triterpenoid production can be achieved using a food additive inducer without the need for a drug inducer.</p>","PeriodicalId":23703,"journal":{"name":"World journal of microbiology & biotechnology","volume":"41 10","pages":"333"},"PeriodicalIF":4.2,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145151184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
