in the wild type strain the exopolygalacturonase activity is stimulated by about 50% by tomato cell wall tissue in the medium

2 entries

optimum production of extracellular exo-polygalacturonase occurs after 36 h, at pH 7.0 and 50�C. Enzyme production is higher in beef extract (1%) as nitrogen source as compared with others (casein, peptone, yeast extract, or ammonium nitrate)

2 entries

the optimum temperature, pH, and incubation period for optimum enzyme production (82.0-83.2 units) are 50�C, 7.0, and 36 h, respectively. Bacillus subtilis produces more exo-PG in culture medium with peptone (1%) than other nitrogen sources such as beef extract, casein, yeast extract, ammonium sulfate, and ammonium acetate

2 entries

using orange peel as carbon source, sugar beet syrup as simple sugar source and potassium phosphate as phosphate source yields the highest enzyme production and activity. Highest enzyme production is obtained at pH 2.0 in 72 h
