This study investigated the impact of the main fatty acids present in waste and fresh oils -palmitic, stearic, oleic, and linoleic acid-on PHA production using Cupriavidus necator H16, focusing on production yield, polymer composition, thermal properties, and microbial viability. Experiments were conducted with low (5 g/L) and high (15 g/L) carbon content for 168 h. Oleic acid was the most effective carbon source, yielding higher PHA production rates, especially noticeable at higher concentrations. The monomer composition and thermal properties of PHAs varied with the type and concentration of fatty acid used. Stearic acid produced PHAs with more 3-hydroxyvalerate and medium-chain length monomers. Microbial viability was consistent across all conditions, except for linoleic acid, which had a detrimental effect. These findings provide key insights into optimizing fatty acid selection to enhance PHA production and tailor polymer properties for industrial applications.","PeriodicalId":258,"journal":{"name":"Bioresource Technology","volume":" ","pages":"131846"},"PeriodicalIF":9.7,"publicationDate":"2024-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142680433","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Hydrolysates obtained from enzymatic degradation of pre-treated post-consumer polyethylene terephthalate bottles in a stirred-tank reactor served as the carbon source for a batch fermentation with an engineered Pseudomonas putida strain to produce 90mg/L of the biopolymer cyanophycin. Through fed-batch operation, the fermentation could be intensified to 1.4 g/L cyanophycin. Additionally, the upcycling of polyethylene terephthalate monomers to the biosurfactants (hydroxyalkanoyloxy)alkanoates and rhamnolipids is presented. These biodegradable products hold significant potential for applications in areas such as detergents, building blocks for novel polymers, and tissue engineering.

In this study, the biological treatment and the filtration performances of AnMBRs for A-sludge digestion under mesophilic and thermophilic conditions were comparatively evaluated through lab-scale experiments, mass balancing and dynamic modeling. Under thermophilic conditions, a higher COD fraction of the influent sludge was converted into methane gas than under mesophilic conditions (65% versus 57%). The energy balance indicated that the surplus energy recovery under thermophilic conditions was less than the additional energy required for heating the AnMBR, resulting in a more than three-fold higher net energy recovery under mesophilic conditions.
