摘要：
The present invention discloses intersexual heterozygous Phycomyces strains. These strains show an improved .beta.-carotene productivity and an increased stability when compared with both the wild type and heterokaryotic Phycomyces strains. The present invention also discloses a method for obtaining Phycomyces transformants without using selection markers. Furthermore, a process is provided for manufacturing .beta.-carotene comprising the use of intersexual heterozygous Phycomyces strains in a submerged culture.
