Abstract/ Executive Summary:

Role of microbes in the retting of jute is inevitable. Microorganisms are widely distributed in nature. Different types of microorganisms were isolated from different sources so far and their retting capabilities were tested. It was assumed that cowdung, cattle urine, sewerage water and plant composts are rich in different promising microbes capable of jute retting. The experiment was undertaken to explore the possibility of using cowdung, cattle urine, sewerage water and plant compost in jute retting for the acceleration of retting speed and improvement of fibre quality in the year of 2004. The jute stem was retted in the water of 200 mL conical flask using 2%, 4%, 6%, and 8% inoculum of cattle urine, cowdung, sewerage water and plant compost separately in identical condition. From the experimental result it was observed that 6% and 8% inoculum of cattle urine retted the green ribbons in 18 and 16 days respectively and yielded best quality (A grade) fibre in comparison with those of other inoculums eg. cowdung, sewerage water and plant compost used in the study. The grades of producing other fibres were B and C.

Keywords: Microbial, Jute retting, Cowdung, Cattle urine, Sewerage water, Plant compost.

Location: Central Research Station, Dhaka.

Start Date: 12-03-2004

End Date: 30-12-2004

Program Area: Postharvest and Agro-processing

Commodity: Jute

Objectives:

To explore the possibility of using cowdung, cattle urine, sewerage water and plant compost in jute retting for the acceleration of retting speed and improvement of fiber quality.

Methodology:

Microbes isolated from cowdung, cattle urine, sewerage water and plant compost sources were grown in PDA/ nutrient broth and other selective media at room temperature using standard microbiological methods. Their retting properties were assessed on jute stem in sterile as well as non sterile conditions.
