background malassezia species as skin microflora of humans and other warm-blooded vertebrates are the lipophilic yeasts associated with various human diseases, especially pityriasis versicolor (pv). objectives the objective of this study was to identify the malassezia species of scraped skin of pv patients in yazd, iran, using morphological, biochemical and physiological methods. we also compar...

background; various industries produce and discharge wastes containing different heavy metals into the environment. apart from using living biomass, dead and dried biomasses have been introduced as a new field of biotreatment technology. method; the cadmium (cd) (ii) removal characteristics of live (growing), dead (autoclaved), and oven-dried biomasses of aspergillus versicolor were examined as...

Hypopigmentary and depigmentary lesions are very commonly encountered group of dermatosis in pediatric age group. : To evaluate the epidemiology clinical characteristics various hypopigmented depigmented patient paediatric A total number 124 children between 0-18 years who presented to dermatology OPD with were assessed evaluated. In this study, most common causes disorders among Pityriasis Alb...

To determine the effect of Artemisia sieberi lotion in signs & symptoms of Tinea versicolor, a randomized, double - blind clinical trial was performed comparing topical application of Artemisia sieberi lotion with Clotrimazole topical lotion, twice daily for 2 week. 60 patients suffering from Tinea versicolor completed the study. 29 patients were treated with Artemisia sieberi lotion and 31 pat...

The impacts of white-rot fungi on altering wood chemistry have been studied mostly in vitro. However, in vivo approaches may enable better assessment of the nature of interactions between saprotrophic fungi and host tree in nature. Hence, decayed and sound wood samples were collected from a naturally infected tree (Carpinus betulus L.). Fruiting bodies of the white rot fungus Trametes versicolo...

Five lignans (secoisolariciresinol, pinoresinol, eudesmin, lariciresinol, and lariciresinol-4-methyl ether) were isolated from an MeOH extract from Araucaria araucana (Mol.) K. Koch wood for the first time in this species and their structures determined with spectroscopic methods. The antimicrobial activities of these compounds were determined for the bacteria Citrobacter sp., Bacillus subtilis...

Polysaccharopeptides (PSPs) are among the main bioactive constituents of Trametes versicolor (T. versicolor). The purpose of this research was to investigate the antioxidant activities of enzymatic hydrolysates obtained from T. versicolor polysaccharopeptides by 80 U/mL β-1,3-glucanase (PSPs-EH80). The half-inhibitory concentration (IC50) of PSPs-EH80 in metal chelating assay, ABTS and DPPH rad...

This is the first report on chemical mutagenesis of Trametes versicolor IBL-04 to develop a hyper-producing mutant for overproduction of manganese peroxidase (MnP) using sugarcane bagasse as a substrate. A freshly prepared inoculum of indigenously isolated T. versicolor IBL-04 was treated with 100 μg mL -1 (v/v) ethyl methane sulfonate (EMS) and ethidium bromide (EB) separately for different ti...
