In this book you can know about cowpea plant and xylanse enzyme. Xylanase enzyme is having very much interest in various industries. Xylanse production from microorganism and its downstream process is quiet difficult and expensive. So we can use plant source like cowpea at different stages of germination for production of xylanase. Here we have observed effect of different factors on purified xylanase activity with protein profiling and enzyme kinetic studies.
