The Virtual University, Pakistan’s first University based completely on modern Information and Communication Technologies, was established by the Government as a public sector, not-for-profit institution with a clear mission: to provide extremely affordable world class education to aspiring students all over the country.

Using free-to-air satellite television broadcasts and the Internet, the Virtual University allows students to follow its rigorous programs regardless of their physical locations. It thus aims at alleviating the lack of capacity in the existing universities while simultaneously tackling the acute shortage of qualified professors in the country. By identifying the top Professors of the country, regardless of their institutional affiliations, and requesting them to develop and deliver hand-crafted courses, the Virtual University aims at providing the very best courses to not only its own students but also to students of all other universities in the country.

Abstract

Pectinase recognized as an industrial important enzymes which occupies 10 percent in enzyme production of world while 25 percent of food production. While keeping in view in the light of above scenario the study was design to produce pectinase from local agro wastes. The Pomelo (Citrus Grandis) was considered as novel substrate for pectinase production through solid state fermentation by Aspergillus niger. In first portion of this study, the OFAT (one factor at a time) was opted for optimizing the conditions of temperature, pH and time period for pectinase production. While the other factor was optimized thorugh RSM-DOE (Respone Surface Methadology), a statistical tool for the analysis of variant factor on pectinase activity. About 14 RSM trial were conducted by employing following condition i.e. Substrate (3-28g), inoculum level (1.5-7.5ml) nitrogen (0.625-1.375g), moisture (5-105%). The highest activity of pectinase was observed at pH (5), temperature (30 °C), incubation day (4 ) by OFAT. In RSM maximum activity at 279.2 U/mL were achieved at optimize temperature 30 °C, pH 5, day 4 th , moisture level 30%, inoculum size 6ml, substrate 3g and nitrogen level at 0.250g. For purification, ammonium sulphate, dialysis and gel chramatograpghy was performed. The results indicates that at 60% ammounium sulphate precipitation was achieved with specific enzyme activity at 0.856U/mg recorded after purification. Present finding proved that Pomelo peel was abundant and cheap source for production at commercial.
