The capacity of Cryptococcus spp to produce melanin in media containing phenol compounds is widely used for identifying these species in the laboratory. The aim of the present study was to compare the production of this pigment by Cryptococcus spp. in four culture media. Sixteen strains of Cryptococcus neoformans, 17 of Cryptococcus albidus, 13 of Cryptococcus laurentii and two of Cryptococcus ...

The vinasse is a by-product generated during the manufacture of alcohol from sugarcane fermentation. Rich in organic matter, it is known that the vinasse has the potential to be used as a source of nutrients for plants as well as microorganisms. In this study, the fungi Pleurotus sajor-caju, P. ostreatus, P. albidus and P. flabellatus were cultivated in vinasse and utilised as a complementary d...

Background: Geographic distance promotes phenotypic variation by facilitating environmental distance, limiting gene flow, and exposing plants to different pollen vectors. Therefore, understanding how plant morphology changes across a geographic range improves our of the drivers morphological diversification both on macro- micro-evolutionary scale.
 Questions: 1) How do location abiotic fac...

Chloroform, methanol, aqueous and ethanolic extracts of the stem bark of Saraca indica were investigated for their antibacterial and antifungal activity against standard strains of Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Bacillus cereus, Klebsiella pneumoniae, Proteus mirabilis, Salmonella typhimurium and Streptococcus pneumoniae and the fungi: Candida albicans and Cryp...

The growth of Torulopsis glabrata was inhibited in glucose-peptone broth containing 10 to 20% normal human serum. Addition of iron to the medium diminshed the fungistatic effect. The intracellular growth of T. glabrata was remarkably restricted within mouse macrophages maintained in vitro, but this growth restriction was not caused by the limitation of iron imposed by the serum in the medium. T...
