Identifying rich, cheap, underused, and readily available starch sources for bioethanol production could help address the problem. Thus, this current study investigated the bioconversion of underutilized <em>Artocarpus altilis</em> (breadfruit) starch to bioethanol using <em>Saccharomyces cerevisiae</em>. The effects of the essential fermentation conditions (fermentation time, breadfruit starch hydrolysate (BSH) concentration, pH, and inoculum size) and their interactions on bioethanol production were investigated. The central composite design was used to generate twenty-one experiments conducted under batch fermentation conditions in the laboratory. The breadfruit starch hydrolysis led to a BSH concentration of 108.9 g/L under a starch concentration of 122 g/L, microwave output of 720 W, and an incubation time of 6 min. For the fermentation of BSH, maximum bioethanol production of 4.99% (<em>V</em>) was reached under the cultivation conditions of BSH concentration of 80 g/L, medium pH of 4.7, inoculum size of 2% (<em>V</em>), and fermentation time of 20.41 h. Except for pH, the impact of each parameter on the bioethanol production was in this order: BSH concentration, inoculum size, and fermentation time. While for the interactions amongst the parameters, the impact is in this order: BSH concentration and inoculum size; BSH concentration and fermentation time; and fermentation time and inoculum size. The results of this study indicated breadfruit starch could be hydrolyzed using acid hydrolysis and microwave irradiation in a relatively short time.

It is urgent to search for safe and efficient inhibitors to prevent reducing sugar induced protein glycation. In this study, we investigated the anti-glycation activity and mechanism of an identified peptide, Asparagine-Tyrosine-Arginine-Arginine-Glutamic acid (NYRRE) from Chinese quince seed protein hydrolysate, by multispectroscopy, confocal imaging, and computational molecular simulation. Firstly, it was found that NYRRE could scavenge hydroxyl radicals and chelate Fe²⁺. Besides, the NYRRE was effective in every stage of fructose induced bovine serum albumin (BSA) glycation. The NYRRE could reduce the formation of fructosamine, carbonyl compounds, glycoxidation products and <em>β</em>-amyloid structure. Meanwhile, NYRRE could protect thiol groups and stabilize the spatial conformation of BSA. The NYRRE presented strong inhibition in fluorescent AGEs, and 68.19% of total AGEs formation was prevented with NYRRE at 15 mmol/L. The results of molecular simulation indicated that NYRRE could insert into the hydrophobic pocket of BSA and interact with hot spots, including arginine and lysine residues. The mechanism of NYRRE inhibiting protein glycation could be due to its antioxidant activity, BSA structure stabilizing ability, and specific bond with glycation sites of BSA. These results provided a valuable reference for developing NYRRE as an efficient antiglycation agent in preventing glycation-mediated diseases.</p></div>","PeriodicalId":52344,"journal":{"name":"Journal of Bioresources and Bioproducts","volume":"8 2","pages":"Pages 187-197"},"PeriodicalIF":0.0,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44473239","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The highest concentration of these compounds is found in the peel (exocarp and mesocarp), which constitutes about 50% of the whole fresh fruit. These bioactive phytochemicals exhibit a broad spectrum of antimicrobial effects against both Gram-negative and Gram-positive bacteria, as well as fungi. In the present paper, the chemical composition and antimicrobial activity of the peel (exocarp and mesocarp) from seven <em>Punica granatum</em> varieties (Wonderful, Mollar de Elche, Primosole, Sassari 1, Sassari 2, Sassari 3, and Arbara Druci) grown in Sardinia (Italy) were evaluated. Polar phenols, flavonoids, condensed tannins, and anthocyanin contents were evaluated by extraction with water at 20 and 40 °C. Orthogonal projections to latent structures discriminant analysis (OPLS-DA) was used to characterize each variety according to the chemical composition of the pomegranate peel extracts (PPEs). The antimicrobial and antibiofilm activities of each PPE were further tested in vitro against <em>Staphyloccocus aureus, Listeria monocytogenes, Salmonella bongori, Escherichia coli, Lacticaseibacillus casei</em> and <em>Limosilactobacillus reuteri</em>. Gram-positive species were more sensitive than Gram-negative to the extracts tested. Antimicrobial activity was shown against <em>S. aureus</em> and <em>L. monocytogenes</em> strains, whereas less, even no activity was found against <em>S. bongori</em> and <em>E. coli</em> strains. The PPEs from Mollar de Elche, Primosole, and Sassari 3 showed the highest antimicrobial activities at concentrations that varied from 0.19 to 1.50 mg/mL, with biofilm activity being reduced by more than 70%. These activities were positively related to the punicalagin, flavonoid, and chlorogenic acid content of the extracts. Finally, regarding the pro-technological bacterial strains, <em>La. casei</em> and <em>Li. reuteri</em> showed very low, even no sensitivity to the used of the specific PPEs with high concentrations. This study proposes a formulation of pomegranate peel extract that valorizes agro-industrial waste in the context of sustainability and circular economy. Pomegranate extracts should be considered potential sources of natural, plant-derived antimicrobials, providing an alternative to artificial antimicrobial products.</p></div>","PeriodicalId":52344,"journal":{"name":"Journal of Bioresources and Bioproducts","volume":"8 2","pages":"Pages 146-161"},"PeriodicalIF":0.0,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46803603","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
