Seasonal changes in individual clearance rates, selective feeding behavior, and population grazing rates of Keratella cochlearis, Polyarthra vulgaris, Polyarthra dolichoptera, and Bosmina longirostris were investigated in a eutrophic lake using five tracer foods (Aerobacter, Rhodotorula, Chlorella, Chlamydomonas, and Euglena) and by in situ radioisotope techniques. Clearance rates ranged from <...

OBJECTIVES The emergence of less common, but clinically important, fungal pathogens including the rare yeasts has contributed to the substantial morbidity and mortality observed in immunocompromised patients. These organisms can be resistant or refractory to existing antifungal agents. We sought to evaluate the activity of the new triazole isavuconazole against these difficult pathogens. METH...

Fungi can cause various diseases, and some pathogenic fungi have been detected in the water of dental equipment. This environment offers suitable conditions for fungal biofilms to emerge, which can facilitate mycological contamination. This study verified whether the water employed in the dental units of two dental clinics at the University of Franca was contaminated with fungi. This study also...

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 ...

Ice deposited in Greenland and Antarctica entraps viable and nonviable microbes, as well as biomolecules, that become temporal atmospheric records. Five sections (estimated to be 500, 10,500, 57,000, 105,000 and 157,000 years before present, ybp) from the GISP2D (Greenland) ice core, three sections (500, 30,000 and 70,000 ybp) from the Byrd ice core, and four sections from the Vostok 5G (Antarc...
