RESUMO
A psychrotrophic bacterium isolated from river sediment was identified as Pseudomonas fluorescens 114. It grew at 0°C and optimally at 20°C. The bacterium produced a protease with a molecular weight of 47,000, which was stable in the pH range of 5 to 9 and worked optimally between pH 6.5 and 10. Activity was optimal at 35°C and was lost immediately at 50°C and after 5 min at 45°C. At 0, 10, and 20°C, 24, 38, and 57% of optimal activity were observed, respectively.
