 Mycology Online -- Rhizopus
The genus Rhizopus is characterized by the presence of stolons and pigmented rhizoids, the formation of sporangiophores singly or in groups from nodes directly above the rhizoids, and apophysate, columellate, multi-spored, generally globose sporangia.
Colonies are fast growing and cover an agar surface with a dense cottony growth that is at first white becoming grey or yellowish brown with sporulation.
Rhizopus oryzae (=R. arrhizus) is the most common causative agent of zygomycosis, accounting for some 60% of the reported culture positive cases, and nearly 90% of the rhinocerebral forms of infection.

 ICSN : A Comparative Study of Chemical versus Biological Functionalizations of Synthetic Intermediates
Direct one step hydroxylations on substrates containing free hydroxy or keto groups can be realized in high yield in the absence of toxic chemicals and organic solvents and without the use of the costly protection-deprotection steps.
Rhizopus arrhizus displayed practically no sensitivity to the absolute configuration in both hydrindene and octaline series, observed ee’s on the biohydroxylated compounds being at the best around 10% when racemic substrates were incubated.
A representative comparison of the chemical and biological 7-hydroxylation is given in the Scheme below; the biological way gives a higher chemical yield and b-selectivity, whereas the chemical transformation gives poor yields for the oxidation step and the opposite selectivity when L-Selectride is used to reduce the intermediate C7-ketone.

 UC IPM: UC Management Guidelines for Rhizopus Root Rot on Sugarbeet
arrhizus are common in most agricultural soils throughout the world; in California, R.
In spite of their wide distribution, both fungi are weak sugarbeet pathogens and tend to only be a problem when the crop is compromised by some other factor such as excess soil moisture, crown injuries, or insect injury (cutworms, armyworms) to roots.
While the symptoms caused by these species are identical, the optimum temperatures for disease development are different: Rhizopus stolonifer causes disease at low temperatures of 57° to 61°F, while high temperatures, 86° to 104°F, favor R. arrhizus.

 Dwyer, Jason Ian - 33628943 - CHEE 4006 - Fermentation of Lactic Acid from Carbohydrate Containing Waste
This individual inquiry is part of a large project, whose objective is to study the fermentation of Lactic acid using suitable microorganism for the fermentation of industrial high carbohydrate containing waste steams.
Generally the pH experiments results show that more lactic acid is produced at a lower pH of 4 relative to a pH of 6 for both Rhizopus arrhizus and Rhizopus oryae.
The concentration experiments show that much more lactic acid is produced with an increase in the initial substrate concentration when Rhizopus Arrhizus is used for fermentation.

 Evaluation of the in vitro activity of the new triazole voriconazole against opportunistic filamentous fungi.   (Site not responding. Last check: 2007-11-04)
Available antifungal therapy is not always effective in controlling most of these severe infections and new agents are needed for optimal therapy.
This study compared the in vitro antifungal activity of the novel triazole derivative, voriconazole (V), with amphotericin B (A), and itraconazole (I) against 5 isolates each of Aspergillus flavus, A. fumigatus, Bipolaris spp., Fusarium oxysporum, F. solani, Pseudallescheria boydii, and Rhizopus arrhizus.
MIC ranges for R. arrhizus were 8 to greater than 16 micrograms/ml with V, 0.5 to greater than 16 micrograms/ml with I, and 0.2-1.0 micrograms/ml with A. These results suggest that V is a potentially effective antifungal for some filamentous pathogens and clinical trials in the treatment of human mycoses are warranted.

The newly developed acid-base and metal-based titrator allowed the characterization of the chemisorption active sites of Rhizopus arrhizus biomass and the study of their metal affinity.
values for Rhizopus biomass varied between −3 and −6 for sites releasing no protons, −1 and 1 for sites releasing one proton, and > 8 for sites releasing two protons - combined with the Pb precipitation phenomenon.
At low temperatures, the active binding site number was lower at lower lead concentrations whereas the precipitation was promoted at higher lead concentration values.
