- Abstract:
- ... Paraburkholderia sacchari revealed an outstanding ability to metabolize D-xylose to xylonic acid. The work described here aimed at finding the operational conditions to promote the production of xylonic acid in bioreactors. Fed-batch assays using xylose as the sole substrate for growth and production attained a xylonic acid concentration of 150 g L⁻¹, corresponding to a productivity of 1.5 g L⁻¹ h ...

- Abstract:
- ... We assess oleaginous yeast strains from five genera to identify the strain suitable to use sugarcane bagasse as a feedstock for lipid production. Upon initial assessment in glucose or xylose media, five potential strains were chosen for further assessment in sugarcane bagasse hydrolysate. All strains exhibited improved growth and lipid production due to a buffering capacity of the hydrolysate, wit ...

- Abstract:
- ... A d-xylose 3,5-anhydrosugar derivative has been used as an oxetane co-monomer in the ring-opening copolymerization (ROCOP) with cyclic anhydrides, to form a family of seven novel sugar-derived polyesters, with up to 100% renewable content. ROCOP proceeds with high alternating selectivity to form AB-type copolymers that are thermally robust (Td,ₒₙₛₑₜ > 212 °C) and exhibit a broad range of glass-tra ...

Among them, preparing lignin-containing cellulose micro/nano-fibrils (LCMNF) is an extremely promising strategy. In this study, LCMNF with a significant amount of lignin were prepared from corncob residues (CCR) left from xylose extraction. The focus of the work was to explore the influence of different ...

This enzyme is not only involved in sugar metabolism but also has industrial applications, such as in the production of high fructose corn syrup and bioethanol. Various crystal structures of glucose isomerase have shown the binding configuration of the substrate and ...

Previously, we presented a novel approach for increasing the consumption of xylose and the lipid yield by overexpressing the genes coding for xylose isomerase (XI) and xylulokinase (XK) in Mucor circinelloides. In the present study, an in-depth analysis of lipid accumulation by xylose metabolism engineered M. circinelloides strains (namely Mc-XI and Mc-XK) using corn straw hydrolysate was to be ex ...

Lactose is a promising cellulase inducer because it is easy to be dissolved, but its induction efficiency is lower than that of solid inducers, such as biomass. We aimed to obtain a cellulase-producing strain that is compatible to on-site production, and develope ...
