The Proteolytic Enzymes of Bacteria
A great deal of work has been done on the proteolytic enzymes of bacteria, especially those enzymes which are secreted into the medium by the living cell or as the result of its autolysis. The proteolytic enzymes of the cells themselves, however, have been less studied. Studies on bacterial peptidases in which substrates of known formulae (such as synthetic peptides) have been used, are few and...
متن کاملProteolytic enzymes from extremely halophilic bacteria.
Halobacterium strains produce a truly extracellular proteinase which degrades gelatine and casein. It has a pH optimum of about 8 and depends upon divalent cations and a high concentration of NaCl or KC1 for activity and stability. Proteolytic enzymes were also found in cell homogenates obtained by ultra sonic treatment. A caseinolytic enzyme, probably different from the extracellular one, is a...
متن کاملGrowth of psychrophilic bacteria.
On the basis of the temperature range in which growth can occur, bacteria are usually divided into 3 groups, namely: thermophiles, mesophiles, and psychrophiles (sometimes called cryophiles or rhigophiles). Thermophiles have temperature optima (generally quite close to temperature maxima) 10 to 25 degrees above the temperature optima of mesophiles. Thermophiles and mesophiles are easily disting...

Upadhyay, J. (Washington State University, Pullman) and J. L. Stokes. Anaerobic growth of psychrophilic bacteria. J. Bacteriol. 83:270-275. 1962.-Facultatively anaerobic psychrophilic bacteria are widely distributed in nature and can be readily isolated from a variety of foods, soil, sewage, and other habitats. Strictly anaerobic psychrophiles, however, could not be isolated. Temperature and ox...

Leipner, J. and R. Saller (2000). "Systemic enzyme therapy in oncology: effect and mode of action." Drugs 59(4): 769-80. Plant extracts with a high content of proteolytic enzymes have been used for a long time in traditional medicine. Besides proteolytic enzymes from plants, 'modern' enzyme therapy additionally includes pancreatic enzymes. The therapeutic use of proteolytic enzymes is partly ba...
