VECTOR FOR THE TRANSFORMATION OF PHAFFIA RHODOZYMA AND PROCESS OF TRANSFORMATION THEREBY

摘要

The present invention relates to a transforming vector and a process of transformation thereby, more specifically to a transforming vector comprisin g a cycloheximide-resistant gene and a ribosomal DNA. The transforming vector and the transforming process thereby is applicable to the efficient and stab le integration of desired DNA into yeast genome, thus providing useful tools fo r the production of a natural pignent, astaxanthin.
