Violacein was isolated from Chromobacterium violaceum, a soil Gram-negative bacterium collected from the forest water body soil sample from Kolli Hills of Tamil Nadu, India. In the present study the anti-diarrhoeal and ulcer-protective properties of violacein were investigated in Wistar rats using castor oil, magnesium sulphate and ethanol. The intestinal(More)
Chromobacterium violaceum, Gram-negative bacteria species found in tropical regions of the world, produces a distinct deep violet-colored pigment called violacein. In the present study, we investigated whether violacein can promote a gastroprotective effect and verified the possible mechanisms involved in this action. For this study, an indomethacin-induced(More)
As the world races towards a plant-based bioeconomy, plants known to be ideal and economical bioreactors are being harnessed for the production of recombinant proteins. The major immunodominant 10 kDa GroES TB antigen (Chaperonin 10) gene from Mycobacterium tuberculosis was selected for expression in plants as a putative tuberculosis (TB) subunit vaccine(More)
The genetic engineering of Mycobacterium bovis-bacillus Calmette-Guérin to express foreign epitopes is an attractive strategy in the field of epitope vaccines. We constructed an 'epitope-trap vector' with Mycobacterium tuberculosis chaperonin-10 as a carrier antigen and used it to express the HIV-1 principal neutralizing determinant epitope. We also(More)
