Summary: This study investigated the production of natural pigments by five filamentous fungi isolated from soil and cultured on a mixture of green waste and whey. Optimal conditions for pigment production were found to be at pH 7.0 and 9.0, with higher biomass and pigment intensities observed in solid-state fermentation compared to submerged fermentation. The study suggests that solid-state fermentation may be a feasible strategy for scaling up pigment production in manufacturing industries.

Summary: This paper introduces the interactions between enzymes in biomass degradation, presenting the concept of the interactome as a holistic approach to depict the interactions among enzymes, substrates, metabolites, and inhibitors for optimizing biomass conversion processes. The interactome provides a better understanding of biomass conversion, allowing production of bioproducts from recalcitrant agro-industrial residues, thus bringing greater value to residual biomass. Finally, technological applications for optimizing the interactome at various levels are discussed.

Summary: Pectinases from Penicillium rolfsii CCMB 714 cultivated in jackfruit seed meal were evaluated for their potential in agroindustrial waste saccharification and orange juice clarification. The results showed that the crude extract of pectinase had optimal activity at pH 3.0-5.0 and 55 degrees C. The saccharification of cocoa husks, mangosteen husks, and passion fruit husks resulted in a significant increase in reducing sugars, and the pectinase also showed potential in clarifying orange juice.

Summary: By using nanoparticles as an active substrate, Surface-enhanced Raman scattering (SERS) can be a reliable technique for detecting and identifying fungi associated with biodeterioration and biodegradation of cultural heritage materials. The size of silver nanoparticles (AgNPs) has a significant impact on the SERS signal enhancement, with 60 nm particles achieving the highest enhancement and showing high reproducibility. Principal component analysis (PCA) can effectively classify and identify fungal strains based on the SERS spectra.

Summary: Multi-copper oxidases (MCOs) are a diverse group of enzymes that use copper ions to reduce O2 to H2O. Laccases, the largest group of MCOs, have a wide range of biotechnological applications. This study focuses on a specific subgroup of MCOs called laccase-ferroxidases (LAC-FOXs) and aims to better understand their classification and structure-function relationships. By analyzing LAC-FOXs from basidiomycete fungi, the researchers identified two subgroups and investigated the key residues responsible for ferroxidase activity. They also conducted site-directed mutagenesis on one specific LAC-FOX enzyme to determine its catalytic activity and the residues essential for its ferroxidase activity.

Summary: Resveratrol was glycosylated by using rXynSOS-E236G glycosynthase, resulting in the production of 3-O-beta-D-xylobiosyl resveratrol as the major product. Response surface methodology was used to optimize the reaction, yielding 35% of 3-O-beta-D-xylobiosyl resveratrol. Xylobiosylation decreased the antioxidant capacity of resveratrol, but significantly improved its solubility for improved delivery and transit to the colon.

Summary: In this study, the quinone reductase activity in three AAO flavooxidases was analyzed, with O-2 as the preferred oxidizing substrate. The results suggest that the aryl-alcohol dehydrogenase activity of these enzymes, although less significant than their oxidase activity, may play a physiological role in fungal decay of lignocellulose by preventing repolymerization through the reduction of quinones. These findings expand the understanding of the role of AAO in lignin biodegradation.

Summary: This study focuses on the microbial fermentation of agro-industrial waste rich in starch for the production of lactic acid (LA) followed by the enzymatic synthesis of polyactic acid (PLA). The microbial interaction was analyzed and the results showed a cooperative relationship between Talaromyces amestolkiae and Lactiplantibacillus plantarum M9MG6-B2, resulting in efficient utilization of sugars from polysaccharides provided as carbon sources. Lactic acid oligomers and polymers were successfully synthesized through LA polycondensation and enzymatic ring-opening polymerization catalyzed by the non-commercial lipase OPEr.

Summary: This manuscript presents a comprehensive study on the molecular mechanisms triggered by the quorum sensing (QS) molecule farnesol in the biotechnologically relevant fungus Ophiostoma piceae. We present for the first time, using a multiomics approach, an in-depth analysis of the QS response in a saprotroph fungus, detailing the molecular components involved in the response and their possible mechanisms of action. We think that these results are particularly relevant in the knowledge of the functioning of the QS in eukaryotes, as well as for the exploitation of these mechanisms.

Summary: This study sequenced the genomes of various Lentinula species and identified four major clades. The sampling of shiitake mushrooms was expanded in China and three lineages within Lentinula edodes were recognized as potential species. Genes involved in the biosynthesis of the organosulfur flavor compound lenthionine were found to have diversified in Lentinula. The pangenome analysis revealed a large number of orthogroups, with only a fraction being shared among all strains, emphasizing the need for conservation of wild populations.

Summary: Lignins released in black liquors from kraft pulp mills are a valuable but underutilized source of aromatics. Enzymatic depolymerization of kraft lignins using alkaliphilic fungal laccases has been made possible by our recent enzyme-directed evolution approach, which generated laccases with high activity and stability at pH 10. Our study demonstrates the ability of these tailor-made laccases to oxidize, demethylate, and depolymerize eucalyptus kraft lignin at pH 10. However, in high enzyme and lignin concentrations, repolymerization of the oxidized products becomes dominant. To overcome this, we successfully conducted the enzymatic reaction in a bench-scale reactor coupled to a membrane separation system.

Summary: Through systematic enzyme engineering, alkaliphilic and thermophilic fungal laccases have been developed to operate under the extreme conditions of high temperature and pH typical of industrial wood conversion processes. These laccases show enhanced catalytic activity at alkaline pH and increased thermal tolerance, enabling them to oxidize kraft lignin at pH 10 and temperature of 70°C. Their integration into industrial processes saves energy and chemicals, improving the efficiency of kraft pulp bleachability and fibreboard production.

Summary: This study compares the performance of a nanofiber device and a resin column for antibody capture. The nanofiber device has a larger housing volume and lower binding capacity, but comparable eluate purity to the resin column. It shows high stability, can be used for multiple cycles, and maintains consistent eluate quality when scaled up. The use of a single nanofiber device can significantly reduce costs compared to a resin column, especially when the number of batches is limited.

Summary: Fed-batch cell culture processes are commonly used in biomanufacturing due to their simplicity and applicability in cGMP environments. However, the challenge lies in the changing physiochemical conditions within the bioreactor as the cell density changes. Traditional response surface models (RSMs) are commonly used for optimization but are limited by their use of time-invariant factors. Dynamic RSM (DRSM) models can predict the time-dependent impact of process inputs, allowing for optimization of process operations that change over time.

Summary: Water for injection (WFI) production in the biopharmaceutical industry consumes excessive amounts of water and energy. Recycling buffers can potentially save up to 90% of resources, but achieving the full theoretical potential is impossible when a risk-aware design is used.

Summary: In this study, heterologous expression and homologous overexpression of ABC transporter proteins AatA and MdlB were found to improve butyric acid production in C. tyrobutyricum. The overexpression of these proteins upregulated the expression levels of key enzymes in the acetate synthesis pathway and promoted the synthesis and secretion of acetic acid. Additionally, the increase in ATPase activity facilitated sugar utilization, induced extracellular secretion of acetate, and shortened fermentation periods.
