Pharmamedia and pectinase production by Bacillus subtilis Mz-12P.

Bacterial isolates collected from the environment were screened for pectinolytic activity, and a strain with the highest activity was selected and identified as Bacillus subtilis Mz-12. The presence of pectin hydrolase, lyase, and esterase activities was confirmed. Pectinase was purified and characterized.

Characterization of subtilosin gene in wild type Bacillus spp. and possible physiological role.

In a designed study to screen for antimicrobial exhibiting bacteria using molecular aspects, Bacillus species were considered to investigate antibiotic biosynthesis genes. 28 bacterial strains and 3 induced mutants were screened for the presence of subtilosin gene (sbo) and subtilosin through PCR and Mass spectrometry respectively. Sbo gene was detected in 16 out of 28 Bacillus strains.

The Chemical Property Position of Bedaquiline Construed by a Chemical Global Positioning System-Natural Product.

Bedaquiline is a novel adenosine triphosphate synthase inhibitor anti-tuberculosis drug. Bedaquiline belongs to the class of diarylquinolines, which are antituberculosis drugs that are quite different mechanistically from quinolines and flouroquinolines. The fact that relatively similar chemical drugs produce different mechanisms of action is still not widely understood.

Evaluating Antimycobacterial Screening Schemes Using Chemical Global Positioning System-Natural Product Analysis.

Most of the targeted discoveries in tuberculosis research have covered previously explored chemical structures but neglected physiochemical properties. Until now, no efficient prediction tools have been developed to discriminate the novelty of screened compounds at early stages. To overcome this deficit, a drastic novel approach must include physicochemical properties filters provided by Chemical Global Positioning System-Natural Product analysis (ChemGPS-NP).
