increasingly popular ever since levi Strauss and Jacob Oavis first made them
for California gold miners in 1873. Now, companies that manufacture blue jeans

A softer denim, called was stone
washed introduced in the 19805. The fabric is not really washed with rocks.
Enzymes, called cellulases, from Trichoderma fungus are used to digest some of the cellulose in the
cotton, thereby softening it Unlike many chemical reactions, enzymes usually operate
at safe temperatures and PH. Moreover. enzymes are proteins, so they are readily degraded for removal from wastewater.
Fabric
Cotton production requires
large tracts of land, pesticides, and fertilizer. and the crop yield depends on
the weather. How-ever. bacteria can produce both cotton and polyester with less
environmental impact
