An acetate-negative mutant of Yarrowia lipolytica Wratislavia K1 was selected that, when grown with 300 g raw glycerol l(-1) at pH 3, produced 170 g erythritol l(-1) after 7 days, corresponding to a 56% yield and a productivity of 1 g l(-1) h(-1). The Wratislavia K1 strain did not produce citric acid.

The internal stem tissues of Ischnosiphon arouma (Aubl.) Körn, an Amazonian plant whose outer cortex is traditionally used in handicrafts, are typically discarded after processing. This study explores the potential of these inner, underutilized fractions as a viable source of high-quality cellulose.

Background: We hypothesized that Aquaporins (AQPs), membrane proteins facilitating water and small molecule translocation, implicate in thoracic aortic aneurysm (TAA) pathogenesis via their deregulation, impairing water transport and detoxification.
Methods: Raw data was extracted from a publicly available dataset. Gene expression profiling was performed with mRNA/miRNA microarrays and differentially expressed genes (DEGs) were identified.

This study explores the potential of using agricultural industrial byproducts to synthesize nanocomposite materials to address the increasing demand for sustainable alternatives to synthetic plastics. Cellulose nanofibers (CNF) were extracted from waste sugarcane bagasse (SCB) through chemo-mechanical treatment and subsequently esterified with 4-aminobenzoic acid (PABA) to obtain modified CNF (mCNF). Wheat gluten protein (WGP), plasticized with glycerol, was used to form films, incorporating CNF and mCNF as fillers.

Traditional plastic films have caused serious environmental issues due to "white pollution". This study isolates lignin from cottonseed hulls to explore alternatives to plastic films. Using both cottonseed hull lignin and commercially sourced white lignin as raw materials, we performed hydroxy-methylation modification via physical and chemical cross-linking to obtain hydroxy-methylated cottonseed hull lignin and hydroxy-methylated white lignin, resulting in hydroxy-methylated lignin with improved hydrophilicity.

The production of bionanocomposite films based on carboxymethyl derivatives of starch and cellulose with sodium montmorillonite (MMT-Na) as a filler was described. The developed films with high absorbency can be used in the preparation of adhesive dressings for wounds oozing as a result of abrasions or tattoos. Carboxymethyl cellulose (CMC), carboxymethyl starch (CMS), and potato starch were used as the raw materials for film manufacturing.
