Enzymatic Synthesis of Fragrance Ester by Lipase from Marine Actinomycetes for Textile Industry

The present study was carried out to investigate the enzymatic synthesis of fragrance ester from brewery industry effluent by lipase of S. acrimycini NGP 1, S. albogriseolus NGP 2 and S. variabilis NGP 3 which was isolated from the marine sediments of South Indian coastal region. The maximum conversion percentage of ester by lipase producing S. variabilis NGP 3 was 48.72 % and also a strong peak at 1745.21 cm-1 was observed by fourier transform infrared (FTIR) spectroscopy which indicated the presence of ester (C = O). The synthesized esters were imparted on the knitted fabric by exhaustion and microencapsulation method. In the qualitative evaluation of fragrance test for exhausted and microencapsulated knitted fabric, the judges were rated ‘2’ (indicates poor) and ‘4’ (indicates fair) respectively for the sensorial fragrance emitted from the fabric coated by the ester of S. variabilis NGP 3. In the quantitative evaluation, fragrance releasing percentage from exhausted and microencapsulated knitted fabric was found as 31.14 and 39.78 respectively on 48 hrs of treatment. Both qualitative and quantitative evaluation of fragrance test indicated that, the microencapsulated ester of S. variabilis NGP 3 on the knitted fabric emitted better fragrance than by exhausted fabric.
