Summary
A heat treatment method to reduce nucleic acid content in cell biomass of a mixed methanol-utilizing bacterial culture was studied. Maximum nucleic acid reduction in the bacterial cells was achieved by using heat shock at 65°C for 5–10 min followed by 2 h incubation at 55°C and 7.2±0.2 pH. In this treatment, 81–85% nucleic acid content was removed from the cells without affecting their true protein content and essential amino acids profile.
