Open AccessBioconversion of non-food corn biomass to polyol esters of fatty acid and single-cell oils
Lignocellulose is a valuable carbon source for the production of biofuels and biochemicals, thus having the potential to substitute fossil resources. Consolidated bio-saccharification (CBS) is a whole-cell-bas...

Tuning the fluorescence of calcium-discharged photoprotein obelin via mutating at the His22-Phe88-Trp92 triad – a QM/MM study†
The fluorescence (FL) of calcium-discharged photoprotein (CaDP) can be altered by easily mutating CaDP without modifying coelenteramide (CLM), which is the decarboxylation product of coelenterazine in calcium-...

Open AccessDetermination of the native features of the exoglucanase Cel48S from Clostridium thermocellum
Clostridium thermocellum is considered one of the most efficient natural cellulose degraders because of its cellulosomal system. As the major exoglucanase of cellulosome in C. thermocellum, Cel48S plays key roles...

Spectrochemistry and artificial color modulation of Cypridina luminescence: indirect evidence for chemiexcitation of a neutral dioxetanone and emission from a neutral amide
We demonstrate that the emission energy of the cypridinid oxyluciferin depends strongly on the polarity and, to a lesser extent, on the basicity of the medium. The emission color can be tuned by environment ef...

Xanthothone, a new nematicidal N-compound from Coprinus xanthothrix
Coprinus xanthothrix was found to have nematicidal activity. Xanthothone was isolated from culture extract guided by activity assay, which was identified as a novel natural product. Two o...
