The presence of anti-nutritional factors in jatropha kernel meal such as, phorbol esters, lectins, trypsin inhibitor, phytate and saponins is of great concern. Toxicity of meal is mainly due to the presence of phorbol esters which limits its use. Several methods have been tried for detoxifying kernel meal that includes physical, chemical, biological and radiation methods. In the study, four different samples, i.e., raw, defatted, one-time mechanically oil expressed and two-times mechanically oil expressed samples were prepared from jatropha kernels. These samples were subjected to biological treatment for phorbol ester degradation. For biological treatment, strain Pseudomonas aeruginosa was used. Cell-free extract obtained from growing strains in a specific media was mixed with kernel meal samples to carry out detoxification. In biologically treated kernel meal, phorbol esters were found to be in range of 0.051-0.102 mg/g which was considered acceptable and hence, the treatment was found to be effective in phorbol ester degradation.
