The influence of zinc, iron, cobalt, and manganese on submerged cultures of Fusarium moniliforme NRRL 13616 was assessed by measuring dry weight accumulation, fusarin C biosynthesis, and ammonia assimilation. Shake flask cultures were grown in a nitrogen-limited defined medium supplemented with various combinations of metal ions according to partial-factorial experimental designs. Zinc (26 to 3...

Cassava (Manihot esculenta), a major staple food in the developing world, provides a basic carbohydrate diet for over half a billion people living in the tropics. Despite the iron abundance in most soils, cassava provides insufficient iron for humans as the edible roots contain 3-12 times less iron than other traditional food crops such as wheat, maize, and rice. With the recent identification ...

The purpose of the present study was to evaluate the identification of 19 Brazilian C. dubliniensis based on the biochemical profile exhibited when tested by the commercial identification kit ID 32C (bioMerieux). Thirteen of the isolates were rigorously identified as C. dubliniensis and the remaining isolates (six) were considered as having a doubtful profile but the software also suggested tha...

Since the classical experiments of Houssay and Biasotti (1), Evans, Meyer, Simpson and Reichert (2), Young (3), and Long and Lukens (4), the diabetogenic potential of pituitary hormones has been amply documented (5). However, the metabolism of glucose by the pituitary has received but little examination (6-9), and the authors have been unable to find any published studies of the hormonal determ...

Candida spp. are known to be the most common fungal pathogens isolated from blood cultures of neonates. The present study was undertaken to know the prevalence of candidemia in neonates and their antifungal susceptibility pattern. Candida isolates were speciated by using germ tube, carbohydrate assimilation and fermentation tests, CHROM agar and Dalmau plate culture method. Antifungal susceptib...

This study was carried out from October 2003 to March 2007 to investigated susceptibility patterns ot March 2007 to antifungals of Candida strains isolated from 410 immunocompromised patients in Shiraz, Islamic Republic of Iran. Patients were checked for systemic candidiasis. Fungal colonization was determined and clinical samples collected from those patients with clinical signs of infections ...

The influence of light, dark, and ambient CO(2) on nitrate assimilation in 8- to 9-day-old barley seedlings was studied. To develop the photosynthetic apparatus fully, the seedlings were grown in nitrogen-free Hoagland solution for 5 days in darkness followed by 3 days in continuous light.The seedlings reduced nitrate and nitrite in both light and dark, although more slowly in darkness. The slo...
