Biosci. j. (Online); 36 (2), 2020
In the Myrtaceae family, the species Eugenia involucrata DC., popularly known as "cerejeira-do-mato", is traditionally used for the antidiarrheal and digestive action of its leaves. However, no studies were found in the literature regarding its antimicrobial and antioxidan...

Amylase from Bacillus sp. Produced by Solid State Fermentation Using Cassava Bagasse as Starch Source

Abstract Amylases are enzymes involved in starch hydrolysis, generating the most diverse products, such as maltose, glucose and dextrins. This work aimed the study of the production of amylolytic enzymes via solid-state fermentation (SSF) using "crueira", an essentially starchy cassava residue, as substr...

Is the efflux pump inhibitor Verapamil a potential booster for isoniazid against Mycobacterium tuberculosis?

The membrane-based efflux pump systems are recognized to have an important role in pathogenicity and drug resistance in Mycobacterium tuberculosis by the extrusion of toxic substrates and drugs from the inner bacillus. This study aimed to investigate the in vitro interaction of Verapamil (VP), an efflux ...
