Highlights
- •
Moringa oleifera straw can used as raw material for fungal cellulases production.
- •
This study of fungi isolated from moringa biomass show three cellulase activities when using crystalline cellulose as source carbon.
- •
Penicillium sp. strain isolated was the most efficient on cellulase activities.
- •
Cladosporium sp. display on crystalline cellulose their higher cellulase activities.
- •
Fusarium sp. is a great source of β-glucosidase activity on carboxymethylcellulose.

Highlights
- •
Lactic acid bacteria were isolated from an artisanal fruit fermented Mexican beverage.

Highlights
- •
The prevalence of syphilis is high in HIV-infected men in Istanbul, Turkey.
- •
The rate of syphilis was found to be significantly higher in MSM HIV infected patients than heterosexual HIV infected patients in Turkey.
- •
Findings of the study highlight the fact that patients infected with HIV must be screened for syphilis at least annually and must be informed about STDs.
