also being used in recent research for remediation of dye containing waste water.
Textile finishing process is based on enzymatic treatment which is environment
friendly. The releasing dyes and aromatic compounds are also being treated by ecofriendly enzymatic process. This is more acceptable to environment due to its less
pollution capacity.
7 Patenting Trends on Use of Microbial Enzymes on Textile
Finishing
Patenting trends of enzymes in textile finishing are also interesting. Cellulase is
mostly used enzyme in textile. As per this perspective, it has been found that there
are a number of petants on cellulase. Europe, United Kingdom, United State have
several patent from 1990s. Previously, patents were done based on application as
detergent or starch. Later, due to some trade legal issues, laundries increased their use
of cellulase [17]. In fact for antimicrobial finishing different types of enzymes from
microbial origin are being used and patented commercially from diverse countries
(Table 2).
