Mucormycosis or black fungus is usually a rare but life-threatening infection resulting from commonly distributed fungi belongingto the Mucorale orders. The disease was previously known as zygomycosis, since Rhizopus species, such as Rhizopus arrhizus, Rhizopus microsporus, and Rhizopus oryza were more isolated from infected patients than Mucor (Chegini et al., 2020, Spellberg, 2017)
اسیدلاکتیک و نمک های مربوط به آن کاربرد گسترده ای در صنعت دارند. کاربردهای اصلی آن در صنعت غذایی، شیمیایی، دارویی و صنایع آرایشی و بهداشتی است. rhizopus oryzae از قارچ های رشته ای مهمی است که توانایی تولید مقادیر بالایی از l-(+)- لاکتیک اسید را دارد. همچنین کشت های قارچی به علت توانایی استفاده از طیف گسترده ای از منابع مانند ملاس و نشاسته و ترکیبات لیگنوسلولزی برای تولید اسیدهای آلی ترجیح داد...
Background and Objectives: Gold nanoparticles have found many applications in cancer diagnosis and therapy, drug and gene delivery and DNA and protein characterizations. Fungi are extremely good candidates in the synthesis of metal nanoparticles because of their ability to secrete large amounts of enzymes. The aim of this study was biosynthesis of gold nanoparticles by a fungus. Materials and M...
A study was carried out on a new strain of Rhizopus stolonifer RCH7 isolated from a spontaneouslyfermenting rice husk sample. Growth characteristics on and utilization profile of various substrates by this isolate were investigated. The isolate was found to display the most extensive mycelia proliferation at a temperature of 37°C and a pH of 4.0. Divalent ionic additions did not cause an increa...
Food stuffs such as maize (Zea mays L.), rice (Oryza sativa), and groundnut (Arachis hypogaea) are important staple foods in sub-Saharan Africa. The aim of this study is to examine the effect storage on food samples plastic, polythene bag, refrigerator, putting into consideration weight microbial load products before after storage. were obtain from Oba market subjected for 28 days, which isolat...
Incubation of sclareol with Rhizopus stolonifer affords in high yield a mixture of triols with 18-hydroxy-sclareol as the main component.
To date, expression of the lipase from Rhizopus oryzae (ROL) in Escherichia coli always led to the formation of inclusion bodies and inactive protein. However, the production of active ROL and its precursor ProROL in soluble form was achieved when E. coli Origami(DE3) and pET-11d were used as expression systems.
The present investigation deals with the kinetics of submerged extracellular lipases fermentation by both wild and mutant strains of Rhizopus oligosporus var.microsporus in a laboratory scale stirred fermentor. Other parameters studied were inoculum size, pH, agitation and rate of aeration. It was found that the growth and lipases production was increased gradually and reached its maximum 9.07±...
Sufu is one of the many soy food products. It is prepared when tofu is fermented with a strain of fungus, producing pehtze, which is then allowed to ripen with various dressing mixtures. Although pasteurization is applied to most commercial sufu, salt-tolerant pathogenic bacteria such as Bacillus spp. and Staphylococcus aureus are still detected in marketed sufu products. This study proposed ne...
