摘要Fishery processing by-products have been of great interest to researchers due to
their beneficial applications in many fields. In this study, five types of marine by-products,
including demineralized crab shell, demineralized shrimp shell, shrimp head, shrimp shell, and squid
pen, provided sources of carbon and nitrogen nutrition by producing a protease from Paenibacillus sp.
TKU047. Strain TKU047 demonstrated the highest protease productivity (2.98 U/mL) when cultured
for two days on a medium containing 0.5% of shrimp head powder (SHP). The mass of TKU047
protease was determined to be 32 kDa (approximately). TKU047 protease displayed optimal activity
at 70–80 C and pH 9, with a pH range of stability from 6 to 11. TKU047 protease also showed stability
in solutions containing surfactants and detergents. Based on its excellent properties, Paenibacillus sp.
TKU047 protease may be a feasible candidate for inclusion in laundry detergents.
