OBJECTIVE To study the mechanism of microbial mutation in aerospace. METHOD Random Amplified Polymorphic DNA (RAPD) was used to analyze the polymorphism of high Lovastatin-producing mutants. RESULT Variations occurred in genomes of these mutants. CONCLUSION The high Lovastatin producibility of the mutants is due to the variation of genomes, therefore(More)
OBJECTIVE To select high Lovastatin-producing microbial breed by space flight. METHOD Monascus purpureus species was carried into space by the recoverable spaceship, "Shenzhou 3". After flight, the strain was rejuvenized, segregated and selected. The content of Lovastatin produced in the solid fermentation was examined. RESULT Mutants with high(More)
