Research progress in submerged mycelial culture of Grifola frondosa, a culinary-medicinal mushroom

Grifola frondosa or maitake, a kind of edible and medical fungus, has become a hotspot. This paper advances how to increase the mycelial growth and bioactive polysaccharide production of G. frondosa by submerged fermentation at home and abroad. It focus on two ways: one is improvement and optimization of G. frondosa self-strain, culture medium and culturing methods, and the other is the effects of adding some...

Rheological characteristics of Ganoderma applanatum exoploysaccharides

Glucose yeast extract peptone media (GYP) proved to be the most suitable medium for organism growth and exopolysaccharides (EPS) production which recorded 0.320 + 0.01 and 0.1+0.01 (mg/ml) dry weight undershaken and static conditions respectively. Rheological study of Ganoderma applanatum exopolysaccharides indicated that viscosity of each EPS concentrations increased with increased shear rate (S.R) values which confirm...

Diversity of putatively toxigenic Aspergillus species in maize and soil samples in an aflatoxicosis hotspot in Eastern Kenya

Aflatoxin contamination impinges on grain quality worldwide. The causative agent, Aspergillus spp. colonizes grain in the field down to postharvest stages in storage where they may produce toxins. Kenya has experienced recurring cases of aflatoxicosis in Eastern region especially during periods of maize grain deficit. The risk of chronic exposure has not been widely studied. Therefore, seasonal variation in abundance...

Evaluation of antifungal activity of novel marine actinomycete, Streptomyces sp. AA13 isolated from sediments of Lake Oubeira (Algeria) against Candida albicans

A new actinomycete strain, designated AA13 was isolated from a marine sediment sample obtained from Lake Oubeira, in the North-East of Algeria and selected for its antifungal activities against Candida albicans. Morphological, physiological and biochemical properties and 16S rRNA gene sequencing strongly suggested that this strain was a new species, which belonged to the genus Streptomyces. Study of the influence of...

Distribution of Malassezia species in Mexican seborrheic dermatitis patients

Yeasts of the Malassezia genus are linked to seborrheic dermatitis (SD) in humans; however, etiological species causing this disease can vary according to their geographical location. M. globosa and M. restricta are the most often isolated microorganisms and can be found in the skin of patients with SD. Nevertheless, species identification by molecular methods and the relationship among etiological agents and the...
