TL;DR: Bioproduction strategies for all rare sugars are illustrated using ring form structures given the name Izumoring.

TL;DR: The influences of initial pH (4.0-9.0), iron concentration (1.2-100 mg/l), nitrogen concentration (NH4HCO3, 0.56-11.28 g/l) and starch concentration (2-32 g/L) on hydrogen production and volatile fatty acid (VFA) production were studied.

TL;DR: The consistency of design and operating parameters for the pilot scale vessels in an existing fermentation pilot plant, ranging in nominal volume from 100 l to 19,000 l, was established and compared favorably with approaches found in the literature.

TL;DR: A pH-stat fed-batch culture by feeding butyric acid and glucose has been studied in an acetone-butanol-ethanol (ABE) fermentation using Clostridium saccharoperbutylacetonicum N1-4 as mentioned in this paper.

TL;DR: In this study, it is found that Lactobacillus delbruekii subsp.

TL;DR: Enhanced productivity is associated with an increase in viscosity of the culture, dispersion of BC pellets, and number of free cells due to agar addition, suggesting that acetan produced by BPR 2001 has a critical role in enhanced BC production.

TL;DR: The present results indicated that methanogens were relatively more sensitive to ammonium than bacteria.

TL;DR: The results suggest that the gel employed for biomaterials can be fabricated from low Td fish collagen by EDC cross-linking during fibril formation.

TL;DR: The optimum temperature, initial pH, amount of added enzyme and substrate (corncob) for the hydrolysis of corncob by Acremonium cellulase and the production of L-lactic acid by simultaneous saccharification and fermentation (SSF) was carried out.

TL;DR: A negative correlation between theamount of methane produced and the amount of Klason lignin was observed in the methane fermentation of steam-exploded bamboo, indicating that unutilized plant biomass can be a useful energy source.

TL;DR: Industrial-scale HSC systems made it possible to steadily produce Chlorella, containing 10-50 times as much phytochemicals as green and yellow vegetables, regardless of the weather.

TL;DR: Ten genes belonging to the hem, cob and cbi gene families involved in the synthesis of vitamin B12 in Propionibacterium freudenreichii are tried to express in an effort to increase the productivity of vitamins B12.

TL;DR: In comparison with the 5'-utR of tobacco mosaic virus (Omega sequence), a known translational enhancer, the NtADH 5'-UTR enhanced translation to a similar level, while the translational efficiency was affected by the sequence context around the AUG initiation codon at the translatory initiation step.

TL;DR: SDS-PAGE analysis of extracellular proteins revealed that the expression of the 55-kDa protein, which was reported as a virulent-strain-specific protein, is controlled by AHLs, suggesting that some virulence factors are regulated by the quorum-sensing system in E. tarda.

TL;DR: Streptococcus bovis 148 was found to produce L-(+)-lactic acid directly from soluble and raw starch substrates at pH 6.0, and the productivity was highest at 37 degrees C.

TL;DR: It is indicated that the cwlO gene is expressed as a monocistronic mRNA during the vegetative growth phase and the substrate bond specificity indicated that it is a DL-endopeptidase.

TL;DR: Microbial production of xylitol from corn cobs using Candida magnoliae was experimentally investigated and charcoal pellets were found to be effective in selectively removing the inhibitors from the hydrolysates without affecting xylose concentration.

TL;DR: A study of protein adaptation strategies suggests that the high activity of psychrophilic enzymes could be achieved by the destabilization of the active site, allowing the catalytic center to be more flexible at low temperatures, whereas other protein regions may be destabilized or as rigid as their mesophilic counterparts.

TL;DR: The Pseudomonas aeruginosa san-ai strain, isolated from water-soluble cutting oil used for cooling and lubrication during industrial metal-working processes, produces an extracellular proteolytic enzyme that is suitable for peptide synthesis and could be used in an intelligent drug delivery system (DDS) designed for applications in the metal industry.

TL;DR: Large differences in colony forming capacity, ethanol production and inhibitor conversion were noted between nine different strains of Saccharomyces cerevisiae in anaerobic batch and fed-batch cultures on dilute acid wood hydrolysate.

TL;DR: It is found that the red tide dinoflagellate Karenia mikotoi (Gymnodinium mikimotoi) generates reactive oxygen species (ROS) and its response pattern was different from that of C. marina, although both responses were almost completely abolished in the presence of superoxide dismutase (SOD).

TL;DR: Purified laccase from a fungus was used for the enzymatic oxidation of bisphenol A and nonylphenol, endocrine-disrupting chemicals, and within 24 h their estrogenic activities were completely removed.

TL;DR: It was found that EDC-SAC had a high degree of cross-linking and high stability compared with DHT-Sac, and this structure resulted in the enhancement of ALP activity of HPDL cells compared with that using EdC-BAC.

TL;DR: Solvent winterization of seed oil and free fatty acids (FFAs) was employed to obtain gamma-linolenic acid (GLA; 18:3omega6) concentrates from seed oils of two Boraginaceae species, Echium fastuosum and Borago officinalis.

TL;DR: It was suggested that the yeast cellular inositol level is one of the important factors which contribute to the high ethanol tolerance implied by the increased cell viability in the presence of ethanol.

TL;DR: An aldoxime dehydratase (Oxd) gene in the 5'-flanking region of the nitrile hydratase-amidase gene cluster in the photoreactive iron-type nitriLE hydr atase-producer, Rhodococcus sp.

TL;DR: G. lucidum GL-1 yakju may become a new functional Korean traditional rice wine with antihypertensive properties, and its angiotensin I-converting enzyme inhibitory activity and SOD-like activity were higher than those of yakju.

TL;DR: An overview of recent advances in the production, stabilization and application of PAC is provided, highlighting the recent biotechnological approaches for the improved catalysis of PAC.

TL;DR: It is demonstrated that temperature shift offers the prospect of enhancing the productivity of pro-UK in high-density perfusion culture.

TL;DR: The NMR spectra of degradation products from PBSA indicated that the adipate units were more rapidly degraded than 1,4-butanediol and succinate units, which seems to be one of the reasons why strain 1-A degraded PBSA faster than PBS.
