[Production of polygalacturonase by Bacillus subtilis cultured with waste and residues as carbon sources]

In the recent study, it was observed that if when the initial pH was 7.0, incubation temperature was 37 degrees C and aeration (150 rpm) was supplied polygalacturonase production by Bacillus subtilis reached to its maximum. Molasses, Vinase and Peach or Apricot pomace were used as carbon sources at differing concentrations and the highest differential rate of enzyme synthesis was detected in the medium prepared with Vinase having a 5% of total sugar content (6.74 delta U/delta O.D.). It also was detected that the waste or residues mentioned above could be used as carbon sources for the polygalacturonase enzyme production by Bacillus subtilis.
