Bioconversion of sodium dodecyl sulphate to rhamnolipid by Pseudomonas aeruginosa: a novel and cost-effective production strategy.

The utility of rhamnolipids in industry is currently limited due to the high constraints in its economic production. In this scenario, the novel utility of sodium dodecyl sulphate (SDS) as carbon source could serve as promising cost-effective strategy. Screening of effective SDS biodegraders led to the isolation of Pseudomonas aeruginosa S15 capable of concomitant SDS degradation and biosurfactant synthesis.

Comparative analysis of mycobacterial truncated hemoglobin promoters and the groEL2 promoter in free-living and intracellular mycobacteria.

The success of Mycobacterium tuberculosis depends on its ability to withstand and survive the hazardous environment inside the macrophages that are created by reactive oxygen intermediates, reactive nitrogen intermediates, severe hypoxia, low pH, and high CO(2) levels. Therefore, an effective detoxification system is required for the pathogen to persist in vivo. The genome of M.
