Industrial enzymes are considered to be the heart of Biotechnology.
There is much scope of R & D resulting in developing number of new
products and improving the process and performances of the existing
products. Here, research work on two industrially important enzymes
xylanase and starch phosphorylase are reported. Degenerate primers are
designed for microbial endo-1,4-β-xylanase gene. These primers may be
exploited for amplification of the gene in a microbe. The approach may
be exploited for production of xylanase using recombinant DNA
technology. Besides, an alkalano- thermophilic xylanase enzyme is
isolated from Bacillus haloduransans. Xylanase has been exploited in
number of industrial uses SP is isolated from seeds of Pennisetum
typhoides and immobilized on brick dust. The immobilized enzyme is found
to have increased thermostability. Increased thermostability of the
enzyme and property of repeated use may be exploited for production of
glucose-1-phosphate, a cytostatic compound used in cardio-therapy.
Commercial applications and Biotechnological exploitation of enzymes are
described.
