    Abstract:

    The protoplasts from Monascus purpureus 9903A were transformed with hygromycin B resistance plasmid pMP-Hygro.The transformation medium contained 50 mmol/L Ca2+ and 40%PEG4000 with 1.0mol/L sorbitol an osmotic stabilizer.The protoplasts concentration is1×108 /mL and the quantity of vectors is 1 μg/100μL protoplasts.In this study,the average transformation ratio is 160 colonies/μg DNA.
