Seleksi Aktinomisetes Penghasil Protease dari Tanah Gambut Desa Langkai, Siak, Riau
Abstract: Actinomycetes is
well known as secondary metabolites producer and hence it has high
pharmacological andcommercial interest. In this study, a total of 14 isolates
of actinomycetes from peat soils in Langkai Village,Siak, Riau had been
selected for their ability to produce protease. Extracellular protease from
Actinomycetesisolates was characterized by incubating the isolate in Nutrient
Agar media containing casein 1%. Screeningof actinomycetes isolates showed that
five isolates had the ability to produce a clear zone with the value
ofproteolytic index (IP) ranged from 5.73 to 11.15. Isolates L313 showed the
highest IP value (11.15), as wellas the highest protease production (0.041
U/ml) in Nutrient Broth media containing casein 1% after 6 daysincubation at
room temperature.
