TL;DR: The major types of nanoparticle that have been used so far are summarized and the possible applications in biological and environmental research, and the potential environmental and health impacts associated with the use of these nanoparticles are discussed.

TL;DR: The rate of soluble chemical oxygen demand (sCOD) removal correlated with digestion time according to the first-order kinetic model developed by Grau et al.

TL;DR: Dehydrogenase activity was found to be a sensitive assay for determining the effect of heavy metals on physiologically active soil microbial biomass and sustains the high applicability of this parameter for soil ecotoxicological testing as reported by other authors.

TL;DR: Although it is obviously important to control harmful biofilm formation, the exploitation of beneficial biofilms formed by such industrial bacteria may lead to a new biotechnology.

TL;DR: It was found that cell immobilization within reticulated polyurethane foam biomass support particles strongly inhibits the secretion of membrane-bound lipase into the culture medium, which suggests that ROL31 localized in the membrane plays a crucial role in the methanolysis activity of R. oryzae cells.

TL;DR: Its marked stability and activity in organic solvents suggest that this lipase is highly suitable as a biotechnological tool in a water-restricted medium with a variety of applications including organosynthetic reactions and the control and prevention of MWF putrification in the metal industry.

TL;DR: This review focuses on the degradation of three hard-to-degrade animal proteins (extracellular matrix proteins, collagen in particular, keratin, and prion proteins) and discusses the decomposing capability of thermophilic bacteria.

TL;DR: This work constructed a metabolically engineered Saccharomyces cerevisiae that produces D-lactate efficiently and obtained the possibility of a new approach for pure d-lactic acid production without a neutralizing process compared with other techniques involving lactic acid bacteria and transgenic Escherichia coli.

TL;DR: The study indicated that a combination of culture-dependent and -independent approaches could be very useful for monitoring both bacterial diversity and the succession of communities during the composting process.

TL;DR: Findings show for the first time that a sulfur oxidation bacterium has a high sulfate tolerance and a high sulfur oxidizing activity below pH 1.5, and this strain is identified as having the highest tolerance for sulfate.

TL;DR: This downstream procedure that uses the integrated bioreactor can be applied to the direct production and purification of other prodigiosin analogues and hydrophobic alkaloid compounds from several microorganisms.

TL;DR: After 42 d of anoxic operation at 35 degrees C, nitrite ion was detected in a fixed-bed reactor effluent supplying ammonium and Fe(III) EDTA Na.

TL;DR: Flashing light from blue LEDs is a promising illumination method for indoor algal cultivation using photobioreactors according to the effects of incident light intensity, duty cycle and frequency on the cell growth and astaxanthin production.

TL;DR: It is isolated, for the first time, an anaerobic gram-positive rod-shaped strain capable of producing equol from daidzein and its 16S rDNA gene sequence showed 99% similarity with that of the human intestinal bacterium SNU-Julong 732 and 93% similarityWith that of Eggerthella lenta ATCC 25559(T) (AF292375).

TL;DR: It is demonstrated that the utilization of distillery wastewater as a sole nitrogen source enables a marine thraustochytrid, Schizochytrium sp.

TL;DR: The combined use of metabolic engineering and physiological modulation in transgenic and wild-type plants, although not fully exploited to date, is likely to provide the sustainable and rational supply of bioactive MIAs needed for human well being.

TL;DR: Five lines of evidence proved the transformation: altered phenotype and its transmittance to the next generation, resistance of T(1) seed germination to geneticin or hygromycin B, the detection of a transgene in T( 1) plants by PCR analysis and Southern hybridization and the rescue of the plasmid consisting of the integrated T-DNA and flanking wheat genome DNA from T(2) plants.

TL;DR: 2, 6-Dimethyl beta-cyclodextrin was the most effective and its solubility was 2.3 mM in a 0.1 M 2,6-dimethylbeta-cyclodesxtrin aqueous solution, and had a 1.23-fold polymerization activity as paclitaxel in a tubulin assay.

TL;DR: This review focuses on recent development with contemporary innovations and perspective of lantibiotic research, which may establish a universal approach to advance the structural design of novel peptides, termed lantIBiotic engineering.

TL;DR: Information on the structure-sweetness relationship for these proteins would help not only in the clarification of the mechanism of interaction of sweet-tasting proteins with their receptors, but also in the design of more effective low-calorie sweeteners.

TL;DR: Candida tropicalis, an osmophilic strain isolated from honeycomb, produced xylitol at a maximal volumetric productivity of 3.5 g l(-1) h(-1), and when cell-recycle fermentation was started with the cell mass concentrated twofold after batch fermentation and performed for 10 recycle rounds, it achieved a very high productivity.

TL;DR: High temperature open lactic acid fermentation is a simple and promising method for producing high-grade L-lactic acid from biomass waste, and FISH analysis of such mixed-culture systems is helpful for monitoring the microflora in these cultures.

TL;DR: For the suspensions of bakers' yeast, the concentration dependency of viscosity was expressed well with some modification for the flow pattern around suspended particles.

TL;DR: Using in vivo in vivo osteogenesis research, it is expected that only internal osteogenesis will be induced and that no external heterotopis ossification will beinduced.

TL;DR: The significance of activation of macrophages through oral or intradermal administration, the discovery of IP-PA1 as a macrophage-activating substance, the chemical structure of IP/PA1, the use of IP+ to improve various disorders, the mechanism of action, and the possibility of application of IP1 to various fields are discussed.

TL;DR: In this system, nitrogen removal ratio was affected by C/N ratio and TOC loading, not by the amount of granular sludge, and stable isotopic analysis using 15N-labeled nitrate showed that N2 gas was formed by anammox reaction.
