Spouted bed drying parameters and adjuvant effects on polyphenol retention and antioxidant activity in mango peel powders

The Canadian Journal of Chemical Engineering, EarlyView.
Spouted bed drying of mango peels with colloidal SiO2 and corn starch produces a free‐flowing powder with reduced agglomeration, increased drying yield, and preserved antioxidant and polyphenol content. Abstract The production of polyphenol‐rich powders is a promising strategy for valorizing agro‐industrial byproducts. This study evaluated drying yield,

Association of improved oxidative stress tolerance and alleviation of glucose repression with superior xylose-utilization capability by a natural isolate of Saccharomyces cerevisiae

Biotechnology for Biofuels, 2018
Background Saccharomyces cerevisiae wild strains generally have poor xylose-utilization capability, which is a major barrier for efficient bioconversion of lignocellulosic biomass.

Oxygenation influences xylose fermentation and gene expression in the yeast genera Spathaspora and Scheffersomyces

Biotechnology for Biofuels and Bioproducts
Background Cost-effective production of biofuels from lignocellulose requires the fermentation of d-xylose. Many yeast species within and closely related to the genera Spathaspora and Scheffersomyces (both of the order Serinales) natively assimilate and ...

Beyond Gut Modulation: A Critical Review of the Therapeutic Potential, Safety, and Clinical Prospects of Natural Polysaccharides for IBD

Food Safety and Health, EarlyView.
In this review, we critically summarized the application of natural polysaccharides (NPs) for the treatment of IBD. This approach combines, in a unique way (right), the basic structure–activity relationships of NPs from different origins (left) with their multipronged mode of action, which involves modulation of the gut microbiota and other ...

Integrated pretreatment and fermentation strategies for L‐lactic acid production from brewers' spent grain using native Streptococcus infantarius and Bacillus coagulans

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Brewers' spent grain (BSG) is an abundant lignocellulosic byproduct of the brewing industry with strong potential as a renewable substrate for biotechnological production of lactic acid (LA). This study evaluated integrated pretreatment, enzymatic hydrolysis, and fermentation strategies to enable efficient production of optically ...

Toward Sustainable Enzyme Production From Agro‐Industrial Residues: Optimizing pH and Soyhull Particle Size in Fungal Fermentation

Journal of Surfactants and Detergents, EarlyView.
Sustainable enzyme production from soyhull fermentation. ABSTRACT Carbohydrase enzymes are critical to sustainable detergent formulations, enabling effective cleaning at lower temperatures and reduced resource use. To improve the economic and environmental viability of enzyme production, this study explored soybean hulls—a low‐value agricultural by ...

Effect of gamma irradiation and storage days on physicochemical, sensory, and microbial quality of pineapple (Ananas comosus) fresh cut under refrigeration

JSFA reports, EarlyView.
Abstract Background Fresh‐cut pineapple is increasingly consumed for its convenience and nutritional value; however, minimal processing accelerates quality deterioration and microbial growth, resulting in substantial postharvest losses. Gamma irradiation is recognized as a nonthermal preservation technique, but limited information exists regarding its ...

Genetic analysis of D-xylose metabolism by endophytic yeast strains of Rhodotorula graminis and Rhodotorula mucilaginosa

Genetics and Molecular Biology, 2011
Two novel endophytic yeast strains, WP1 and PTD3, isolated from within the stems of poplar (Populus) trees, were genetically characterized with respect to their xylose metabolism genes. These two strains, belonging to the species Rhodotorula graminis and
