Cellulosic sugars production for the valorization of lignocellulosic biomass residues in an industrial site has economic benefits and is promising if integrated into a biorefinery. Enzymatic hydrolysis (EH) pretreated Eucalyptus globulus bark, residue low-economic value widely available Portuguese pulp paper mills, could be excellent approach to attain resource circularity mill profitability. This work evaluated potential improving cellulosic concentrations by operating with high solids loading introducing additives Triton X-100, PEG 4000 Tween 80 using commercial enzymatic consortium dosage 25 FPU gcarbohydrates−1. Additives did not improve performance, but effect increasing 14% (w/v) batch operation was accomplished. The fed-batch strategy investigated and, when starting 11% loading, allowed feeding 3% fresh feedstock sequentially at 2, 4 6 h, attaining 20% total loading. After 24 h operation, concentration reached 161 g L−1, corresponding EH conversion efficiency 76%. Finally, fermentability hydrolysate Ethanol Red® strain 5 L bioreactor scale. present results demonstrate that previously kraft pulping, production, allowing it become raw material wide range bioprocesses.

White Rot Fungi (WRF) are a class of microorganisms widely understood for their ability to breakdown an extensive range pollutants generally found in industrial wastewater. This specific literature review centers on the abilities treat wastewater, analysis biodegradation mechanism, future applications, and scaling up practical implementation. WRF usually carry out degradation process with ligninolytic enzyme by targeting complex pollutants, such as aromatic hydrocarbons, dyes, pharmaceuticals, products personal care. The unique enzymatic system converts harmful into harmless end byproducts, thus minimizing impact environment ecosystem. paper also discusses potential applications WRF, bioremediation, biosorption, co-culturing bacteria enhance removal efficiency already functional wastewater treatment plants. However, there still challenges WRF-based facilities due factors optimization conditions processes conventional plants, cost effectiveness, design modifications facilities. Conclusively, fungi can play important role degrading organic inorganic specifically, which not treated

Microbial Enzyme Systems in the Production of Second Generation Bioethanol

Sustainability, Год журнала: 2023, Номер 15(4), С. 3590 - 3590

Опубликована: Фев. 15, 2023

The primary contributor to global warming has been the careless usage of fossil fuels. Urbanization’s threat depletion these resources made it necessary find alternatives due rising demand. Four different forms biofuels are now available and constitute a possible replacement for first generation is generated from edible portion biomass, second non-edible third algal fourth using molecular biology improve strain. Second-generation extremely important because they derived such as agricultural agro-industrial wastes rich in cellulose, hemicellulose, pectin, starch impregnated with lignin, hydrolyzed after delignification by physio-chemical or biological pretreatments ligninases. enzymes involved hydrolysis feedstocks production second-generation bioethanol, highly acceptable biofuel, discussed this article. Furthermore, article discusses various fermentation technologies well significant developments biofuel combining microbial enzyme systems.

Microbial co-cultures for biochemicals production from lignocellulosic biomass: A review

Bioresource Technology, Год журнала: 2023, Номер 386, С. 129499 - 129499

Опубликована: Июль 17, 2023

Global reliance on fossil oil should shift to cleaner alternatives get a decarbonized society. One option achieve this ambitious goal is the use of biochemicals produced from lignocellulosic biomass (LCB). The inherent low biodegradability LCB and inhibitory compounds that might be released during pretreatment are two main challenges for valorization. At microbiological level, constraints mostly linked need axenic cultures preference certain carbon sources (i.e., glucose). To cope with these issues, review focuses efficient conversion via sugar platform as well an innovative carboxylate taking advantage co-cultivation microorganisms. This discusses novel trends in microbial communities co-cultures aiming at different bioproducts co-generation single reactors sequential bioprocess combination. outlook further perspectives have been outlined future successful development.

Advances in fungal sugar transporters: unlocking the potential of second-generation bioethanol production

Applied Microbiology and Biotechnology, Год журнала: 2025, Номер 109(1)

Опубликована: Янв. 22, 2025

Second-generation (2G) bioethanol production, derived from lignocellulosic biomass, has emerged as a sustainable alternative to fossil fuels by addressing growing energy demands and environmental concerns. Fungal sugar transporters (STs) play critical role in this process, enabling the uptake of monosaccharides such glucose xylose, which are released during enzymatic hydrolysis biomass. This mini-review explores recent advances structural functional characterization STs filamentous fungi yeasts, highlighting their roles processes cellulase induction, carbon catabolite repression, signaling pathways. The review also emphasizes potential genetic engineering enhance specificity efficiency these transporters, overcoming challenges substrate competition limited pentose metabolism industrial strains. By integrating latest research findings, work underscores pivotal fungal optimizing production advancing bioeconomy. Future prospects for transport systems implications biotechnology discussed.
