Methods for improved retting included modifying water retting or dew retting to remove the inherent problems and to select specific retting microorganisms. Retting time must be carefully judged; under-retting makes separation difficult, and over-retting weakens the fibre. Retting process is used for obtaining fibres from steins of flax, hemp, jute etc. The traditional water‐retting process, without inoculum addition, was compared to a process modified by inoculating water tanks with two selected pectinolytic bacteria: the anaerobic strain Clostridium sp.
