  Candida lipolytica YB is able to incorporate fatty acid from the culture medium when lipids are used as carbon substrate. The composition of cell lipids is largely dependent on that of the culture medium. An important Δ 9 desaturase activity acts on incorporated palmitic and stearic acids; and Δ eicosenoic and erucic acids are shortened to oleic by: The extracellular acid phosphatase was slightly inhibited by NaF, in contrast with the significant inhibition of the intracellular form. KH(2)PO(4) inhibited both activities equally. In this work, a pressurized bioreactor was used for Yarrowia lipolytica batch cultivation under increased air pressure from 1 to 6 bar. Cell growth was strongly enhanced by the pressure rise. Clinical, microbiological, and experimental animal studies of Candida by:

pastoris [18], to improve oxygen transfer rate to aerobic cul-tures. However, above certain limits increased air pressure and the consequent raise on oxygen partial pressure have detrimen-tal effects on yeast cell activity. It was proven that oxygen toxicity, total pressure, is the main cause of cell inhibition [19,20]. /$. Candida lipolytica es un patógeno humano infrecuente. Es una levadura que se encuentra en el suelo, vegetales, mamíferos, y en contadas ocasiones en la boca, el tracto respiratorio, y el intestino de individuos sanos.

SKIPTON, K. WATSON,* R. L. HOUGHTON . In the field of nanotechnology, the use of various biological units instead of toxic chemicals for the reduction and stabilization of nanoparticles, has received extensive attention. Among the many possible bio resources, biologically active products from fungi and yeast represent excellent scaffolds for this purpose. Since fungi and yeast are very effective secretors of extracellular enzymes Cited by:

2 partial pressures higher than mbar (corresponding to air at 1 bar). In many cases, increased O 2 partial pressure (higher than approximately 1 bar) is toxic to aerobic cultures and inhibits microbial growth and product formation [7]. During the reduction of molecular oxygen to water through acceptance of four electrons, reactive. Candida lipolytica yeast, grown on 1% methanol as the only carbon and energy source, synthesized % of dry cell mass as lipids, % of which were polar lipids. Polar lipids consisted mainly of phospholipids and sphingolipids as their minor components. The total long-chain bases content has been found to account only for % of the polar by: Candida lipolytica (strain ATCC ) was grown on a simple defined medium with n‐dodecane as sole carbon source under batch and continuous fermentation composition of cellular material recovered from the fermentations, the oxygen demand of the cells, and the effect of operating conditions on cell growth were evaluated experimentally.   Abstract. Candida glabrata has become a leading cause of invasive infections around the world and is exhibiting growing resistance to azole antifungals. To study the mechanism of its azole resistance, we analyzed the efflux pumps and found well known increased efflux expression and low metabolic state in all azole-resistant by:
