Tóm tắt

BIOLOGICAL CHARACTERISTICS OF THE STRAIN Aspergillus terreus VNA 05 AND THEIR LOVASTATIN BIOSYNTHESIS CAPABILITY

This paper presents some biological features and lovastatin biosynthesis capability of strain A. terreus VNA 05. It is found that the strain is capable of lovastatin biosynthesis and develops well in pH from 5 to 7.5 and at temperature 28oC - 30oC. The train consumes  some  commonly  used  carbon  sources  (glucose,  saccharose,  glycerol,

mannose, lactose) and nitrogen sources (yeast extract, soybean powder, corn extracted water, peptone). A. terrus VNA 05 also yields enzyme activities hydrolyzing starch, casein, gelatin, xelluloza, which are favorable conditions for selecting nutrients during lovastatin fermentation.
