TL;DR: A strain, designated TN-484, producing itaconic acid with a high yield was successfully obtained by selection using an itaconIC acid concentration-gradient agar plate technique after NTG-treatment of Aspergillus terrerus IFO 6365.

TL;DR: Good correlation was found between the linear growth rates of Chlorella and the light supply coefficient and when various other types of both internally illuminated and externally illuminated cylindrical photobioreactors were used, this demonstrates that irrespective of the cell type, photoboreactor type and size, the proposed light supply coefficients can be used for quantitative evaluation of light condition inside the photobiOREactor.

TL;DR: In this article, the adsorption of bovine serum albumin (BSA) and gelatin onto stainless steel surfaces was studied as a function of pH, using nonporous stainless-steel particles.

TL;DR: NADPH-dependent d -xylose reductases from Candida tropicalis IFO 0618 were purified and characterized and revealed three XR isomers, which showed that both XR1 and XR2 were dimers composed of identical subunits.

TL;DR: Temperature dependency of the production of iturin A and surfactin by a dual producer, Bacillus subtilis RB14, in the solid-state fermentation of okara was investigated and only the ratios of homologues having β-amino acid residues with normal aliphatic chains were affected.

TL;DR: Nine strains of lactic acid bacteria that hydrolyze starch were isolated from burong isda, an indigenous fermented food made from fish and rice in the Philippines, and it is suggested that pLTK13 carries a gene necessary for synthesis of amylolytic enzyme, which hydrolyzed soluble starch, amylopectin, glycogen, and pullulan and to a small extent amylose.

TL;DR: The relative significance of the exponential and linear growth phases during light-limited batch cultivation of Chlorella pyrenoidosa C-212 and Spirulina platensis M-135 cells was investigated and the existence of the various growth phases could be predicted by a simple mathematical model.

TL;DR: In this article, the effects of water on enzyme (protein) hydration and catalytic efficiency of enzyme molecules in organic solvents have been analyzed in terms of the thermodynamic activity of water, which has been estimated by the NRTL or UNIFAC equations.

TL;DR: Under oxygen transfer rates (OTR), Candida boidinii NRRL Y-17213 exhibited both NADH and NADPH linked d -xylose reductase activities with the former being higher than the latter, and xylitol dehydrogenase was mainly NAD dependent.

TL;DR: In this paper, two-stage extractive fermentation using Lactobacillus delbrueckii was examined, and 40% Alamine 336 diluted with oleyl alcohol, and oleyal alcohol, respectively, were selected as the extractant and the back extractant, respectively.
