Short-chain cello-oligosaccharides (COS; degree of polymerization, DP ≤ 6) are promising water-soluble dietary fibers. An efficient approach to their bottom-up synthesis is from sucrose and glucose using glycoside phosphorylases.

This study investigated two bioleaching strategies for removing heavy metals from three mine tailings fractions generated by flotation processes. On the one hand, with microbial consortia of acidophilic mesophiles and moderate thermophiles efficiently extracted Co, Cu, Zn, As, while leaching Pb was facilitated through use organic acids produced a heterotrophic bacterium fungus. Approximately 100% 68% 63% 31% Cu were bioleached barite (BT) sample after 14 days, whereas concentrate (BC) results showed about 70% Zn 45% removal at same period. The sulfide (SC) underwent both consortia, over 28 days. Approximately, 67% 28% 56% 6% Mn using mesophiles, efficiency 72% 50% 36% 5% in 20 L bioreactors. other explored Gluconobacter oxydans fungus Penicillium simplicissimum production gluconic acid citric acid, respectively. Additionally, besides glucose-based media, glycerol crystal sugar tested as alternative cheaper carbon sources. metabolic activity P. allowed maximum 39–43% BT days glycerol-based medium, BC sample, extraction around 60% medium. A lower achieved G. samples. 34% 39% reached within 7 when glucose used source. Further optimization should address enhancement – especially reduction costs related to media formulation fungal biomass on larger scale.

The primary goal of this scoping review is to collect, analyze, and critically describe information regarding the role main compounds (reuterin, phenyllactic acid, exopolysaccharides) produced by LAB that possess antifungal properties provide some suggestions for further research. use lactic acid bacteria (LAB) mitigate spoilage extend shelf life foodstuffs has a long history. Recently, there been growing interest in unique these additions which they are applied. In recent studies biopreservation, significant attention given microorganisms their metabolites. This fascinating discipline aims not only replace traditional preservation systems, but also improve overall quality final product. biologically active by-products synthesized under certain conditions (time, temperature, aerobiosis, acidity, water activity, etc.), can be enacted through one oldest approaches food processing: fermentation (commonly used dairy bakery sectors). study delves into biosynthetic pathways synthesized, with particular emphasis on what known about mechanisms action against molds relation type food.

Abstract Pectin-rich agro-industrial residues are feedstocks with potential for sustainable biorefineries. They generated in high amounts worldwide from the industrial processing of fruits and vegetables. The challenges posed to implementation efficient bioprocesses however manyfold thoroughly discussed this review paper, mainly at biological level. most important yeast cell factory platform advanced biorefineries is currently Saccharomyces cerevisiae , but species cannot naturally catabolise main sugars present pectin-rich hydrolysates, particular d -galacturonic acid l -arabinose. However, there non- (non-conventional yeasts) considered advantageous alternatives whenever they can express highly interesting metabolic pathways, natively assimilate a wider range carbon sources or exhibit higher tolerance relevant bioprocess-related stresses. For reason, interest non-conventional yeasts biomass-based gaining momentum. This paper focuses on valorisation by exploring that vast versatility use substrates their hydrolysates robustness cope multiple stresses encountered. major progresses made related isolation, selection, sugar catabolism, engineering S. -derived strains bioconversion residue discussed. reported examples value-added products synthesised different using reviewed.

The important industrial protein production host Komagataella phaffii (syn Pichia pastoris) is classified as a non-conventional yeast. But what exactly makes K. non-conventional? In this review, we set out to address the main differences 'conventional' yeast Saccharomyces cerevisiae, but also pinpoint other yeasts used in biotechnology. Apart from its methylotrophic lifestyle, Crabtree-negative species. even within methylotrophs, possesses distinct regulatory features such glycerol-repression of methanol-utilization pathway or lack nitrate assimilation. Rewiring transcriptional networks regulating carbon (and nitrogen) source utilization clearly contributes our understanding genetic events occurring during evolution mechanisms mating-type switching and triggers morphogenic phenotypes represent further examples for how distinguished model S. cerevisiae. With respect heterologous production, high secretory capacity secretes only low amounts endogenous proteins. Different Golgi apparatus stacked like mammals. While it tempting speculate that architecture correlated secretion levels different N-glycan structures observed phaffii, there recent evidence against this. We conclude with unique has lot potential explore both fundamental research questions applications.
