Abstract

The metabolites of bacteria Bacillus cereus and Bacillus pumilus isolated from soil samples in Shimoga region, Karnataka (India) were tested for cytotoxicity and anticancer properties. The various solvent extract fractions obtained from the metabolites of the two bacteria were tested for their cytotoxicity against normal human liver cell lines and 2 cancer cell lines by (3(4,5dimethylthiazol2yl)2,5diphenyltetrazolium bromide, a tetrazole) assay. The two fractions obtained from B. cereus showed high cytotoxicity. These two fractions were further screened for anticancer activity by nuclear staining studies and DNA fragmentation analysis. Both the fractions demonstrated significant activity by membrane blebbing during nuclear staining and caused the damage the DNA patterns during DNA fragmentation analysis. On the other hand, the metabolites of B. pumilus revealed toxic effect against cancer cells as well as normal ones.
