Bioprocessing of “Hair Waste” by Paecilomyces lilacinus as a Source of a Bleach-Stable, Alkaline, and Thermostable Keratinase with Potential Application as a Laundry Detergent Additive: Characterization and Wash Performance Analysis

Figure 7

Washing performance analysis of the P. lilacinus enzyme preparation in the presence of the commercial detergent Skip. Analysis were done at 30°C ((a)–(f)) and 40°C ((g)–(l)), for 30 m ((a)–(c) and (g)–(i)) and 60 m ((d)–(f) and (j)–(l)). Cloth washed with tap water ((a), (d), (g), and (j)); ((b), (e), (h), and (k)) cloth washed with Skip; ((c), (f), (i), and (l)) cloth washed with Skip added with crude enzyme of the P. lilacinus protease.
