DNA Recombinant Technique For Producing Transgenic Rumen Microbes In Order To Improve Fiber Utilization

Abstract

The ceUulolytk baderia IsoIaCed from the buffalo and cattle namen - RumUtOCOCClU illblU, R. jUlvefacim8, and BaderoUln .uccUtogem - had various adh1ties. The capabWty of these haderia 10 deerade ceUulose ranln from 12.7 10 43.2 '10 per day.
