Retting is a microbial process by which the fibre from the woody core (stick) is loosened. Breed, R. S., Murray, E. G. D., and Smith, N. R. 1957. Article  Bacteriarespon-sible for the retting of Brazilian flax. Abstract Four bacterial strains with high balanced polygalacturonase (PG) and pectin lyase (PNL), and xylanase with minimal cellulase activity were used in jute retting. Soc. Retting is facilitated by anaerobic butyric acid bacteria such as Clostridium botulinum, Clostridium tetani and Clostridium perfringens. In this work, we recorded for the first time the retting activity ofastrain of AuAromobacter parvulus. Several soil quality parameters influence fiber quality. There is a little evidence on the record that aerobic bacteria take active part in the retting of jute and allied fibre plants (Ali et al., 1972; Alam and Asaduzzaman, 1993; Haque et al., 1992).
