TL;DR: The present study confirmed that macroalgae represent an attractive alternative renewable feedstock for biodiesel and other biofuels.

TL;DR: The relationships among fermentation conditions (in terms of pH and shaking/agitation speed), mycelial morphology, and the production of Monascus yellow pigments were investigated in both shake-flask and scale-up bioreactor experiments to facilitate large-scale production of these natural pigments.

TL;DR: Investigation of changes in low molecular weight hydrophilic and volatile compounds of soy sauce using gas chromatography/mass spectrometry (GC/MS)-based non-targeted metabolic profiling suggested a novel finding that lactic acid bacterium affected the production of several constituents such as cyclotene, furfural, furFuryl alcohol and methional in the soy sauce fermentation process.

TL;DR: Results suggest that PEDOT-HA/PLLA film combined with ES are conducive to cell growth and neurite outgrowth, indicating the conductive PEDot- HA/P LLA film may be an attractive candidate with ES for enhancing nerve regeneration in nerve tissue engineering.

TL;DR: A simple colorimetric paper-based biosensor based on a novel principle for the detection of antibiotics inhibiting bacterial protein synthesis, including aminoglycosides, tetracycline, chloramphenicol, and macrolides is developed.

TL;DR: An enzyme that catalyzes C-3 epimerization between d-fructose and d-allulose was found in Arthrobacter globiformis strain M30 and it is suggested that this enzyme represents an ideal candidate for the industrial production of d- allulose.

TL;DR: The well diffusion, minimum inhibitory concentration (MIC), and minimum bactericidal concentration (MBC) assays determined that the S. bombicola-mediated fermented extract has excellent activity, followed by B. amyloliquefaciens and L. brevis, respectively.

TL;DR: S. cerevisiae JRC6, based on its ability to ferment sugars at a higher temperature, can be a promising candidate for production of ethanol from lignocellulosic biomass via SSF process.

TL;DR: A two-stage process model was designed according to the present study to achieve semi-industrial waste PCBs recycling and economic feasibility analysis indicated that the process was profitable.

TL;DR: 3D structures of a PET model compound bound to the crystal structures were built, and mutated the putative substrate-binding site predicted from the models, and the enzymatic activities of the mutants for the model substrate poly(butylene succinate-co-adipate) were experimentally determined.

TL;DR: The aim of this research is to develop a highly sensitive analytical method for the enantioseparation of chiral amino acids without any derivatization process using liquid chromatography-tandem mass spectrometry (LC-MS/MS) and establish a quantification method that allowed the simultaneous analysis of 18 d-amino acids with high sensitivity and reproducibility.

TL;DR: A combined method of partial Fenton's oxidation and biological treatment using activated sludge for decolorization of azo dyes, which represent an important group of recalcitrant, toxic textile dyes is developed and evaluated.

TL;DR: Findings indicate that genetic manipulation of O. polymorpha will be more convenient and accelerated by using the CRISPR/Cas9 system, which is applied as a powerful genome editing tool in this methylotrophic yeast.

TL;DR: A strategy for further engineering to improve the MVA production in E. coli is proposed based on 13C-metabolic flux analysis, which suggested additional requirement of NADPH for MVA synthesis was obtained from the transhydrogenase reaction in the engineered strain.

TL;DR: Results suggest that the nori sauce has a high potential as a novel nutritional source for humans and food safety and inhibitory activity of angiotensin-converting enzyme was observed.

TL;DR: This study detected six bacteria that participate in the degradation of aromatics derived from lignin, which have rarely been reported in rumen fluid, and suggests that the aromatics were converted into acetate via benzoate.

TL;DR: Analysis of the microbial community structure of the anode biofilm and the planktonic bacteria based on 16S rRNA gene sequences suggested that Geobacter sp.

TL;DR: Electrochemical performances and community structures of two algae cathode photosynthetic MFCs were investigated and compared and revealed the addition of riboflavin (RF) and neutral red (NR) decreased the redox current of the SMFC but promoted that of UMFC.

TL;DR: Water-extracted ADR fermented by L. acidophilus for 48 h was found to be the best skincare agent or antioxidant agent and the physiological activities of fermented extracts were considerably higher than those of unfermented extracts.

TL;DR: PCR analysis of genomic DNA from resultant colonies revealed the excision of both the marker and Cre expression construct, indicating that the self-excising marker cassette was efficient at removing the selectable marker.

TL;DR: This approach has the best performance for d-amino acid analysis that includes the shortest analytical time, the highest enantioseparability without derivatization, and the largest coverage for analytical targets (more than one hundred targets including non-proteinogenic amino acids and amines).

TL;DR: Compared with the traditional red mold rice, using millet as substrate is promising for high production of monacolin K in the solid-state fermentation of M. ruber.
