In this study, twenty-five whey samples collected from dairy industries in the city of Isfahan. The sampleswere cultured on malt extract broth (MEB) and yeast extract glucose chloramphenicol agar (YGCA) media.Eleven yeast strains (designated M1 to M11) were isolated from the culture. The strains were identified bytheir morphological and physiological properties. Betagalactosid...

In this article, we present a method to delete genes in filamentous fungi that allows recycling of the selection marker and is efficient in a nonhomologous end-joining (NHEJ)-proficient strain. We exemplify the approach by deletion of the gene encoding the transcriptional regulator XlnR in the fungus Aspergillus niger. To show the efficiency and advantages of the method, we deleted 8 other gene...

Brine fermentation by osmophilic lactic acid bacteria and yeasts for long periods of time is essential to produce a good quality of shoyu (Japanese fermented soy sauce). It is well known that lactic acid fermentation by osmophilic lactic acid bacteria results in the depression of alcoholic fermentation by osmophilic yeasts, but the nature of the interaction between osmophilic lactic acid bacter...

chromagar candida is a new chromogenic culture medium that is used for the isolation and direct identification of some of the most clinically important yeast pathogens on the basis of colony colour. the aim of the study was to isolate and identify candida species from the oral cavity with chromagar candida. samples (158) from 68 orthodontic patients wearing upper removable orthodontic appliance...

background recent evidences have revealed that in more than 65% of microbial infections, biofilms have critical roles. the ability of yeasts to form biofilms on surface of medical devices such as urine catheters is an important reason of the capability of these microorganisms to cause human disease. objectives the aim of this study was to isolate and identify yeasts on the surfaces of urine cat...

background and purpose: candida species are the most opportunistic fungi affecting the nails and resulting in onychomycosis. in this study, we identified and evaluated in-vitro susceptibility of the recovered isolates against fluconazole (flc), voriconazole (vrc), and clotrimazole (clt) using the clinical and laboratory standards institute (clsi) m27-a3 document. materials and methods: from pat...
