Regarding laccase delignification, the use of <em>Hormonema</em> sp. and <em>T. villosa</em> laccases did not show evidence of delignification of steam-exploded material, and rather low glucose and xylose recoveries were obtained during saccharification assays of laccase-treated samples compared with their respective controls. With regard to laccase detoxification, the reduction of the total phenolic inhibitors content presents in steam-exploded material by both laccases (phenols removal of 47 % and 60 % by <em>Hormonema</em> sp. and <em>T. villosa</em> laccases<em>,</em> respectively), triggered the fermentation by <em>Saccharomyces cerevisiae</em> of laccase-treated samples when 0.2 g L<sup>−1</sup> of inoculum was used during a simultaneous saccharification and fermentation (SSF) process. Moreover, when the inoculum was increased from 0.2 to 1.0 g L<sup>−1</sup>, both laccases shortened the yeast lag phase during the SSF process. Then, faster glucose consumption and ethanol production rates (ethanol productivity values of 0.25 and 0.28 g L<sup>−1</sup> h<sup>−1</sup> for <em>T. villosa</em> and <em>Hormonema</em> sp. laccases, respectively, compared to 0.02 g L<sup>−1</sup> h<sup>−1</sup> for control samples) were noticed.

Whey permeate, a by-product of cheese manufacturing with high lactose content, could be considered a promising substrate for microbial growth to yield value-added products. Whey permeate was therefore investigated as a potential feedstock for the production of polyhydroxyalkanoates (PHAs) by <em>Hydrogenophaga pseudoflava</em> DSM1034. Although the ability of this microorganism to grow and accumulate PHAs on whey permeate has been previously demonstrated, the PHAs yields were notably low. Therefore, a meticulous inoculum optimization was performed, taking into consideration adaptation to lactose-containing substrates, initial bacterial concentration, and growth kinetics. In media containing lactose as a carbon source, the lag phase, exceeding 40 hours in non-optimized conditions, decreased to only 4 hours. In whey permeate, a cell dry weight (CDW) of 5.49 ± 0.08 g/L was obtained. PHAs fraction in CDW and PHAs yield were 52.48 ± 3.14 % of CDW and 0.144 g/g of consumed sugar, respectively. Furthermore, these results were achieved in flask without hydrolysis of lactose contained in the permeate. Moreover, no galactose remained unutilized in the spent broth demonstrating that <em>H. pseudoflava</em> DSM1034 metabolized both sugars contained in lactose. Additionally, in culture media containing mixtures of glucose and galactose, microbial growth was lower compared to growth on comparable amounts of lactose. This study underscores the potential of whey permeate as a valuable resource for the production of PHAs, offering a sustainable solution for the utilization of dairy industry by-products, mitigating its environmental impact and promoting sustainable resource utilization.</div></div>","PeriodicalId":19190,"journal":{"name":"New biotechnology","volume":"87 ","pages":"Pages 72-81"},"PeriodicalIF":4.5,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143567767","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
