    ABSTRACT: Xylitol is a pentitol, a natural sweetener, found its application in food/ pharmaceutical industries, exploited especially for its anti-cariogenic properties. Xylitol is a valuable product with rising demands in market, it becomes significant to study and optimize the production with more of economic justification. In this work, xylitol obtained by biotechnological methods was based on fermentation by yeast isolated from sugarcane extracts collected from the Sathyamangalam, Tamilnadu, India. Yeast isolates were identified using conventional microbiological approach, modern metagenomic analysis and the gene sequence was deposited in NCBI repository. The growth of Candida parapsilosis strain BKR1 (NCBI accession no.:KC462059) andits xylitol production capability were assessed. The single factorial optimization revealed that pH, Temperature and initial substrate concentration was 4, 30ÂșC and 0.1 g/ml respectively.

    ABSTRACT: Polyacrylonitrile fiber is one of the important fiber because of their warm feeling, bulky hand, good resiliency, higher wrinkle resistance and favorable aesthetic properties. This study was focused on the characterization of polyacrylonitrile polymer and optimization of process parameters of wet spinning machine for development of of acrylic fiber. Polyacrylonitrile powder was characterized for average molecular weight and viscosity. Process parameter such as dope concentration, roller speed, coagulation bath concentration were optimized. The obtained fibers were characterized for its micro-structure using scanning electron microscope and performance properties in the term of denier and tenacity.
