background and objectives: synthetic dyes are recalcitrant to degradation and toxic to different organisms. decolorization of textile wastewaters is one of the major concerns since last decades. physical-chemical treatments are very expensive and frequently producing large amounts of toxic wastes. biological treatments can be more convenient. in the present study, an attempt has been made for d...

Yarrowia lipolytica is a potentially useful host for heterologous protein production. To develop an efficient culture method for high cell density cultivation and heterologous gene expression of Y. lipolytica, the effects of medium components and their concentrations on the growth of Y. lipolytica have been investigated. Addition of yeast extract to the culture media was found to significantly ...

Two hundred thirty-two nonfilamentous bacterial strains, including saprophytes, plant pathogens, and opportunistic plant and human pathogens, were screened for the ability to produce cutinases (cutin-degrading esterases). Initially, esterase activity of culture filtrates of strains grown in nutrient broth-yeast extract medium supplemented with 0.4% apple or tomato cutin was determined by a spec...

The potential use of date syrup, for the production of carotenoids by Rhodotorula glutinisin batch fermentation process, was investigated during 7 days. The results revealed that carbon (glucose or date syrup) and nitrogen sources [yeast extract, (NH4)2SO4 and NH4NO3] had a significant influence on biomass and carotenoid production. Maximum yield of total carotenoid production (7.94 mg/L) with ...

Lipophilic yeast of the genus Malassezia (Pityrosporum) belongs to the normal flora of human skin and many warm-blooded animals. These fungi can produce a diverse range of diseases that the best known and most frequent of them is pityriasis versicolor, a chronic recurrent skin disease occurring primarily in tropical regions. The genus Malassezia has been recently enlarged to include seven disti...

OBJECTIVES To document the microscopic features of vaginal candidiasis and to examine the relation between yeast morphology and patient symptomatology. METHOD The study population comprised women undergoing screening for genital infection at a department of genitourinary medicine. RESULTS/CONCLUSION Data were collected on 267 women of whom 234 were found to have vaginal candidiasis by vagin...
