Abstract
Many industries including fermentation, pulp and paper industry, brewing sector,
fermentation, food and animal feed industry, and detergent and textile use
cellulases due to its environment benign and sustainable process. Academic and
industrial researches are being done and still ongoing on cellulases due to its
enormous industrial application and make these processes green. In this article,
extensive review is performed on the use of cellulases in the industrial sector in
both crude and pure form. It has been observed that crude cellulases are preferred
in the industrial sector due to its low cost and stimulate the process using
impurities present in enzymes. Pure cellulases are mainly used in laboratories
and are case specific as they are costly to use in industries.

10.1 Introduction
Lignocellulosic biomass is becoming more dominating alternative due to its environment friendly nature in terms of combustion compared to fossil fuel, rapid
diminishing trend of fossil fuel reserves, and ever-increasing energy demand along
with the clean environment point of view. They are readily available and
