TL;DR: The biochemical pathways of methane to poly-β-hydroxybutyrate (PHB) in type II methanotrophs have been analyzed and used to propose stoichiometric equations for cell biomass and PHB as mentioned in this paper.

TL;DR: In this paper, the authors isolated hydrogen-producing photosynthesis bacteria from muddy water in the Tsukuba area with butyrate as a carbon source, and the maximum rates per irradiated area by the immobilized cells of the selected strains were 321, 253, 348, and 337 μl/h/cm2 from butyrates, acetate, lactate and the mixture of the above organic acids, respectively, at 10 klx at 30°C.

TL;DR: In this paper, the mechanism of the formation of 2,3-butanediol isomers in Bacillus polymyxa was studied and two enzymes were separated by Blue Sepharose CL-6B and their stereospecificities were identified using all of the pure isomers of 2 3 butanediol (R(−), S(+)m, and meso), acetoin (R (−) and S(+)) and the separation and measurement of these isomers.

TL;DR: The cell number of the bacteria during steady state H 2S removal was proportional to the inlet H2S concentration, verifying the kinetic equation derived previously.

TL;DR: In this article, the removal of NH 3 by the peat was principally by physical and chemical adsorption with functional groups of humic substances of the PEAT, and the maximum removal rate was about 70 percent of the nitrifying capacity which was, in this study, quantified by 48 h nitrification capacity.

TL;DR: Intraspecific protoplast fusion was carried out between different citric acid-producing strains of Aspergillus niger, and Citric acid productivity of one heterodiploid was intermediate between those of parent strains in both shaking and solid cultures.

TL;DR: In this article, a proportional-differential (PD) control program was used to correct the errors of a feedback control system of volatile carbon source feeding and dissolved oxygen (DO) level.

TL;DR: Electron microscopic analysis showed that the aggregated cells were entrapped or surrounded by an amorphous complex support, as determined by anaerobic incubation using a non-growth medium containing KNO 3 as a substrate and potassium aspartate as a carbon source.

TL;DR: In this article, the efficiency of a bio-reactor using pumice stone was studied, and the cell density of the PUMICE was 18-19 g per liter.

TL;DR: The effects of lactate and ammonium concentrations on the growth of HL-60 and RPMI 8226 human cells were kinetically evaluated in a suspension culture system and it was possible to stimulate the culture processes of the human cells.

TL;DR: One hundred and eighty strains of black aspergilli isolated from cassava fields and factories in Thailand were screened for the activity of raw cassava starch-digestive glucoamylase and Aspergillus sp.

TL;DR: Xylulose reductase from Pachysolen tannophilus IFO 1007 was purified by Sephadex G-100 gel chromatography with three columns and DEAE cellulose chromatography and was entirely homogeneous on disc gel electrophoresis.

TL;DR: Kinetic and energetic analyses were made to describe the accumulation of lipid in Rhodotorula glutinis more quantitatively and the energetic efficiency of lipid formation was higher than that of growth.

TL;DR: A stirred catalytic basket reactor with immobilized yeast cells was used for the batchwise production of ethanol and volumetric productivity was considerably better than that of conventional stirred tank reactors.

TL;DR: The results suggest that the bacterial growth inhibition at high concentration of NTA is caused by the sequestration of metal ions in the medium.

TL;DR: The stoichiometry of the maximum l -serine formation showed that the resting cells carried the highly active methanol dehydrogenase while serine transhydroxymethylase was rather low, and an unusual curve was observed due to the effects of the added NaOH which was used for controlling the pH.

TL;DR: In this paper, the effects of a bulking agent on the reaction rate of sewage sludge composting was investigated quantitatively, and it was shown that the addition of rice husks may increase air-solid interfaces where microorganisms can selectively grow to make colonies.

TL;DR: Erwinia carotovora FERM P-7576, a soft-rot pathogen screened for biochemical pulping, was used to dispose of pectic wastewater discharged from orange canning factories as a pretreatment for an activated sludge process as discussed by the authors.

TL;DR: By this control system, ammonium ion concentrations in culture supernatants of fed-batch cultures of Escherichia coli and Saccharomyces cerevisiae could be maintained vitrually at constant levels.

TL;DR: Simultaneous saccharification and ethanol fermentation of sago starch using amyloglucosidase (AMG) and immobilized Zymomonas mobilis ZM4 on sodium alginate was studied in this article.

TL;DR: Low intracellular S -lactoylglutathione concentration was postulated to account for the observed growth arrest of Saccharomyces cerevisiae cells with hybrid plasmid pYMG14 carrying a gene for NADPH-dependent methylglyoxal reductase of the yeast.

TL;DR: In this paper, the outer peel covering the corn grain was used for preparation of koji, which was applied to alcoholic fermentation without cooking of raw strachy materials, and the results showed that corn hull koji had lower saccharifying power, α-amylase, CMCase and xylanase than wheat bran koji, but higher protease and pectinase activities.

TL;DR: Fundamental properties of the trp promoter were investigated in fed-batch culture using a recombinant containing the lacZ gene controlled by this promoter, and on-off regulation of the promoter was achieved by controlling the tryptophan level during fed- batch culture.

TL;DR: The batch-cultured activated sludge was found to show a far higher rate of glucose uptake but a comparable rate of true growth, that is, growth accompanied by synthesis of nucleic acids and proteins, which later decreases gradually with the progress of DNA, RNA and protein synthesis.

TL;DR: In this article, the authors studied the effect of beet particle size on various fermentation parameters, including pulp size and hammer mill size, and showed that the primary consideration for grind size is energy consumption for grinding.

TL;DR: An esterase was isolated and purified from baker's yeast by ammonium sulfate precipitation and column chromatographies on Sephacryl S-200, DEAE-Sephacel, chromatofocusing, and DEAE -S-200 as discussed by the authors.

TL;DR: In this article, Escherichia coli with γ-galactosidase activity or Saccharomyces cerevisiae was immobilized within a thin κ-carrageenan gel film on a ceramic honeycomb-monolith.

TL;DR: Ethanol-using yeasts, strains IM-10, WY-1, -2, -3, -4, and NK-4, were isolated from natural sources after enrichment culture in a medium containing 8% (v/v) ethanol as a sole carbon source.
