TL;DR: Two acetate containing media were developed for astaxanthin production by a green unicellular alga, Haematococcus pluvialis and pyruvate was an especially good carbon source both for the algal cell growth and the carotenoid synthesis.

TL;DR: The solvent tolerance of Gram-negative and Gram-positive bacteria were determined by the solvent parameter, log P. The solvent-tolerance of bacteria tested were in the following order, Pseudomonas>Escherichia, Serratia, Klebsiella>Proteus, Achromobacter, Acinetobacteriophilus, Aeromonas, Flavobacterium>Alcaligenes, Bacillus>Agrobacterium, Micrococcus, Staphylococcus>Streptococcus, Lactobacillus

TL;DR: A bacterium, capable of the degradation of hydrogen sulfide, methanethiol (MT), and dimethyl sulfide (DMS), as well as dimethyl disulfide (DMDS), was isolated on a thiosulfate plate from a suspension of DMDS-acclimated peat on the basis of its morphological, physiological and chemotaxonomical characteristics.

TL;DR: Two plate culture methods for the highly selective isolation of the soil actinomycetes Micromonospora and Microbispora, are described, which utilize the differential antibiotic resistance of these microbes and the superior ability of their spores to withstand deleterious agents.

TL;DR: In this article, the reaction of glutaraldehyde with various amino and thiol compounds was investigated to elucidate the chemical nature of the compound, and the average molar ratio of the amino and aldehyde groups consumed during the reaction was found to be in a range of 0.3-0.2.

TL;DR: Findings suggest the existence of a unique metabolic pathway for butanol production from CO in this strain of Butyribacterium methylotrophicum, which has now exhibited n-butanol production directly from CO gas.

TL;DR: In this article, Hyphomicrobium sp. was identified as a bacterium capable of removing dimethyl sulfide (DMS), methanethiol (MT), dimethyl disulfide (DMDS), hydrogen sulfide, and DMSO.

TL;DR: The stoichiometry shows that the hydrogen consumption per one mole of CO2 for PHB production is larger than that for cell formation, and that the PHB accumulation in the oxygen-limited culture was superior than that in an ammonium-deficient culture.

TL;DR: The peat biofilter inoculated with strain HA43 enhanced the maximum removal rate for H2S 6-fold compared with the biofilter without strainHA43, and the removal characteristics for sulphur compounds well reflected the removal behaviour of the H 2S-acclimated peatBiofilter where this strain was isolated.

TL;DR: In this paper, a thermostable alkaline protease (Protease B18) was newly obtained from a thermophilic alkalophile, which had a higher optimum pH and temperature around 13.0 and 85°C, respectively, compared with Protease B21-2.

TL;DR: Observations indicate that A. diazotrophicus is an interesting organism for the industrial production of gluconic acid.

TL;DR: Special algorithms for control of the glucose feed rate were applied to eliminate the threat of acetic acid excretion due to overfeeding, and at the same time, to reduce excessive CO 2 evolution caused by unnecessarily severe glucose limitation.

TL;DR: Comparison of amino acid sequences among these enzymes and other known glutaryl 7-ACA acylase and penicillin G acylases showed that there was 10 to 25% homology distributed heterogeneously along the sequences.

TL;DR: Glyceride synthetic action of mono- and diacylglycerol lipase (MDGL) from Penicillium camembertii U-150 was investigated and Glycerolysis of fatty acid vinyl ester by MDGL yielded monoglyceride with a higher yield (90% of total peak area from TLC/FID analysis).

TL;DR: A bacterial strain H65-7 isolated from soil as an inulin-assimilating microorganism produces inulin fructotransferase (inulase II) which converts inulin into di-d -fructofuranose-1,2′:2,3′-dianhydride (DFA III).

TL;DR: The dielectric measurement method is a promising method for estimating on-line cell concentrations in bioreactors and the linearities were maintained practically under cultivating conditions in which temperature, pH, and salt and substrate concentrations were changing during cultivation.

TL;DR: Polyphosphate accumulating bacteria were isolated from activated sludge cultured in a fill and draw system with alternating anaerobic and aerobic conditions and micro-aerophilic growth conditions were required for the induction of phosphorus accumulating activity.

TL;DR: The reaction mechanism in a microorganism is much more complicated than that of an ordinary chemical reactor, and a deterministic model for the application to the control or the simulation of fermentation processes cannot easily be constructed.

TL;DR: Arthrobacter sp.

TL;DR: Morphological and physiological properties of the two strains were closely similar to each other, except that the cells of strain A-1 showed flocculation during growth on a medium containing alginate as a carbon source.

TL;DR: Palleroni's chemotactic method was complemented by using γ-collidine as a substitute for the originally used chemoattractant, potassium chloride, and by using humic acid-vitamin (HV) agar in place of the isolation medium, starch-casein agar as discussed by the authors.

TL;DR: A production process that reduces fermentation time and supplies the proper characteristics to the culture broth for a better recovery of lipase is suggested, which provides the highest lipase production.

TL;DR: The specific metabolic activities of bacterial trophic groups were the highest for H2 followed by lactate, acetate, and propionate, which were correlated with the respective population number within the granules.

TL;DR: A new mold of Penicillium rugulosum, isolated from rot dahlia tubers, was found to produce a very active inulin-hydrolyzing enzyme, which might be used industrially to prepare highly concentrated fructose syrup.

TL;DR: In this paper, a kinetic model for the production of lactic acid by Lactobacillus delbruckii from glucose has been developed using the batch kinetic data of Luedeking.

TL;DR: The use of leucomycin and tunicamycin increased the selectivity of HV agar for streptosporangia and dactylosporaangia, respectively, through elimination of the growth of unwanted actinomycetes which remained after the employment of pretreatments.

TL;DR: In this article, a pilot-scale study of thermophilic anaerobic digestion of high-strength wastewater (evaporator condensate, EC) discharged from a kraft pulp production process was performed.

TL;DR: Since an extract from the mixed culture was able to digest freeze-dried sewage sludge, the isolated bacilli were thereby concluded to be the dominant microflora in the sewagesludge composting process.

TL;DR: Know-how of skilled operators concerning the management of the traditional sake brewing process was analyzed using fuzzy control theory, and a fuzzy control system for regulating the moromi (sake mash) temperature was constructed.

TL;DR: Lactate dehydrogenase activity in this system was maintained at a high level, resulting in reduction of fermentation time to complete batch culture within 38 h, and ED-F with an MF module enabled high speed batch culture.
