background and objective: microbial protein production can resolve one of the major world challenges, i.e. lack of protein sources. candida tropicalis growth was investigated to specify a medium to reach the highest cell proliferation and protein production. material and methods: fractional factorial design and the index of signal to noise ratio were applied for optimization of microbial protei...

Most cases of candidiasis have been attributed to C. albicans, but recently, non- Candida albicans Candida (NCAC) species have been identified as common pathogens. The ability of Candida species to form biofilms has important clinical repercussions due to their increased resistance to antifungal therapy and the ability of yeast cells within the biofilms to withstand host immune defenses. Given ...

The present study is aimed at assessing the ability of metal-resistant yeast, Candida tropicalis CBL-1, to uptake metal from liquid medium. The minimum inhibitory concentration of Cd(II) against Candida tropicalis CBL-1 was 2,800 mg/L. The yeast could also tolerate Zn(II) (3,100 mg/L), Hg(II) (2,400 mg/L), Ni(II) (2,200 mg/L), Cr(VI) (2,000 mg/L), Pb(II) (1,100 mg/L), and Cu(II) (2,200 mg/L). T...

Although Candida dubliniensis is a close genetic relative of Candida albicans, it colonizes and infects fewer sites. Nearly all instances of candidiasis caused by C. dubliniensis are restricted to the oral cavity. As cell surface hydrophobicity (CSH) influences virulence of C. albicans, CSH properties of C. dubliniensis were investigated and compared to C. albicans. Growth temperature is one fa...

Minocycline, a new tetracycline derivative, was found to inhibit the growth of Candida albicans. Inhibition was much affected by the composition of the medium and was difficult to demonstrate in fluid cultures. Study of the rate of budding in shallow broth cultures in Petri dishes showed that the addition of 20 mug/ml minocycline prolonged the lag phase by three hours. C. tropicalis was similar...

Bioaccumulation of synthetic dyes viz. Acid Blue 93, Direct Red 28 and Basic Violet 3 by the environmental yeast isolate, Candida tropicalis growing in aqueous extract of sugarcane bagasse medium was studied in a batch system as a function of initial pH and dye concentrations. The optimum pH value for bioaccumulation was found to be 3.0 for Acid Blue 93 and Direct Red 28 and 5.0 for Basic Viole...

Unstructured models for cell growth, xylose consumption and xylitol production were applied to describe the fermentation kinetics of using Candida tropicalis in synthetic medium,and non-detoxified oil palm empty fruit bunch (OPEFB) hydrolysate at 100 mL flask scale. In medium, experimental maximum specific growth rate (μmax) mass yield factor(YX/S) closer results Tessier model than those Contoi...

CHROMagar Candida is a new differential culture medium that allows selective isolation of yeasts and simultaneously identifies colonies of Candida albicans, Candida glabrata, Candida tropicalis and Candida krusei. We evaluated this medium and compared it with a reference medium, Sabouraud glucose agar, for the presumptive identification of yeast species isolated directly on the medium from 1150...

The total DNA per cell and DNA synthetic cycle phases were determined by flow cytometry in five Candida isolates including three species: Candida albicans 208R1, Candida tropicalis ATCC 750, and Candida parapsilosis 970, 3138, and ATCC 22019. The cells were prepared for flow cytometry by fixation in Carnoy fixative followed by staining with mithramycin. Marked but stable and reproducible inter-...

Xylose reductase (XR) is the first enzyme in D: -xylose metabolism, catalyzing the reduction of D: -xylose to xylitol. Formation of XR in the yeast Candida tropicalis is significantly repressed in cells grown on medium that contains glucose as carbon and energy source, because of the repressive effect of glucose. This is one reason why glucose is not a suitable co-substrate for cell growth in i...
