Fabrication and Characterization of Graphene Microcrystal Prepared from Lignin Refined from Sugarcane Bagasse

open access: yesNanomaterials, 2018
Graphene microcrystal (GMC) is a type of glassy carbon fabricated from lignin, in which the microcrystals of graphene are chemically bonded by sp3 carbon atoms, forming a glass-like microcrystal structure.

Recombinant production of Paenibacillus wynnii  β-galactosidase with Komagataella phaffii

open access: yesMicrobial Cell Factories
Background The β-galactosidase from Paenibacillus wynnii (β-gal-Pw) is a promising candidate for lactose hydrolysis in milk and dairy products, as it has a higher affinity for the substrate lactose (low K M value) compared to industrially used β ...

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

open access: yesFEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Recombinant production of acidophilic L-arabinose isomerase from Lentilactobacillus parakefiri in Bacillus subtilis

open access: yesMicrobial Cell Factories
Background The monosaccharide D-tagatose is a promising alternative to sucrose because of its similar sweetness and lower glycemic index. A novel L-arabinose isomerase (L-AI) from Lentilactobacillus parakefiri DSM 10551 (L-AI-Lp) has been biochemically ...
