[Inhibition of Bacillus pumilus AR03 on Alternaria alternata and Erysiphe cichoracearum on tobacco].

This study aimed to evaluate the efficiency of Bacillus pumilus AR03 against Altenaria alternata and Erysiphe cichoracearum. The antagonistic activities were studied in the way of co-culture on plate, inhibition of pathogen conidia germination on concave slides and LB agar medium. In the investigation, the water suspension of living cells of strain AR03, at 3 x 10(8) cfu . mL-1 had a remarkable in...

Nitric Oxide Production Inhibition and Anti-Mycobacterial Activity of Extracts and Halogenated Sesquiterpenes from the Brazilian Red Alga Laurencia Dendroidea J. Agardh.

BACKGROUND: Red algae of the genus Laurencia J. V. Lamouroux are a rich source of secondary metabolites with important pharmacological activities such as anti-tumoral, anti-inflammatory, anti-fungal, anti-viral, anti-leishmanial, anti-helminthic, anti-malarial, anti-trypanosomal, anti-microbial as well as anti-bacterial against Mycobacterium tuberculosis.
