Effect of polymers on pelleting of Rhizopus arrhizus
Transactions of the British Mycological Society, 1987Cultures of Rhizopus arrhizus in complex or defined media in shake-flasks were found to form pelleted growth morphologies. When polymeric substances which increased medium viscosity were added, cultures grew in a more dispersed form. The most effective polymers were those which could bind divalent cations from solutions.

Microsatellite analysis of the population structure in Rhizopus arrhizus
Journal of Applied Microbiology, 2020Rhizopus arrhizus is recognized as an emergent agent of superficial and invasive mucormycosis. Despite an increasing number of these infections, the molecular epidemiology of Rhizopus species has not been well studied.In this study, 43 R. arrhizus strains (25 environmental and 18 clinical isolates) were genotyped using six novel panels of ...

Fatty Acid Ethyl Esters of Rhizopus arrhizus
Science, 1971Gas chromatographic and mass spectrometric analyses on selected lipid fractions revealed for the first time the presence of ethyl esters of long-chain fatty acids as biological products. Ethyl esters of oleic, palmitic, and stearic acids were detected in relative concentrations of 21.2, 2.4, and 1.5 percent, respectively, of the total methyl and ethyl ...

Production of fumaric acid by immobilized Rhizopus arrhizus on net
Bioresource Technology, 2013An immobilization method using net was developed for fumaric acid fermentation by Rhizopus arrhizus RH-07-13. The large surface of the net immobilized enough filamentous mycelia which produced fumaric acid rapidly. Net size and spore concentration were optimized to enhance fermentation performance and 150cm(2) of net size, 0.5×10(6)per ml of spore ...

Degradation of Dyfonate in soil inoculated with Rhizopus arrhizus
Canadian Journal of Microbiology, 1974The fungus Rhizopus arrhizus, capable of degrading the soil insecticide Dyfonate in shake cultures, was added to a 14C-Dyfonate-treated soil (Piano silt loam) to test its capability to degrade the insecticide in a soil environment. Scanning electron microscopy showed that this soil was a poor substrate for the growth of microorganisms and that the ...

Biotransformations with Rhizopus arrhizus: Preparation of enantiomers of sulcatol
Biotechnology Letters, 1993Microbial reduction of 6-methyl-5-hepten-2-one (1) and hydrolysis of (±)-sulcatol acetate (4) yielded (S)-(+)-sulcatol (2) and (R)-(-)-sulcatol (5) respectively using Rhizopus arrhizus.

Chiral synthesis of alpha-phenylpyridylmethanols with Rhizopus arrhizus
Biotechnology Letters, 1998The bioreduction of 2-benzoylpyridine (1a) with Rhizopus arrhizus afforded (S)-(+)-alpha-phenyl-2-pyridylmethanol (2a) in 82% enantiomeric excess (e.e.) while the asymmetric hydrolysis of its racemic acetate resulted in the antipode (R)-(-)-2a with 24% optical purity.

Reactive dye biosorption by Rhizopus arrhizus biomass
Enzyme and Microbial Technology, 2002The biosorption of three commonly used reactive dyes, from aqueous solutions by oven-dried Rhizopus arrhizus biomass was studied in a batch system with respect to pH, initial dye concentration and initial metal ion concentration. The biomass exhibited maximum dye uptake at pH 2 due to its positively charged nature at acidic pH and the anionic nature of
