Process for enzymatic deinking of printed papers

A process for enzymatic deinking of printed papers inclusive of xerographic and inkjet- printed paper printed with non impact and non dispersible ink comprising:

• a) growing the bacterial isolate Vibrio alginolyticus having accession number NIO/DI/32, the culture being deposited at ARS Patent Culture Collection under NRRL Number NRRL-B-30638, in a novel medium at a temperature ranging from 27° C. to 37° C. for 3-4 days;
• b) removing the bacterial cells by centrifugation under sterile condition to obtain cell free culture supernatant;
• c) incubating the xerox or inkjet-printed paper pulp diluted to 3-12% consistency in sea water with salinity diluted to 50% with the resulting cell free culture supernatant obtained from step (b) at 20% concentration for at least 72 hours at room temp followed by diluting the pulp ten fold in water to obtain completely decolorized pulp without traces of ink in the supernatant;
• d) filtering the resulting pulp obtained from step (c) under suction to get the desired deinked paper.
