The invention relates to the technical field of microorganisms, and discloses a strain of marine
aspergillus versicolor and an isolated culture method and application thereof, wherein the preservation number of the marine
aspergillus versicolor is GDMCC No: 61106, and the marine
aspergillus versicolor is classified and named as
Aspergillus versicolor SCAU141. The marine
aspergillus versicolor separation culture method is easy to operate, the strain is convenient to obtain, and the marine
aspergillus versicolor has the capability of preparing the exopolysaccharide; the method for preparing the exopolysaccharide by utilizing the marine
aspergillus versicolor is simple and mild in condition; the prepared exopolysaccharide has remarkable anti-
cancer activity, and has a good inhibition effect on the growth of three common
cancer cells such as
lung cancer,
liver cancer and
colonic adenocarcinoma; in addition, the prepared exopolysaccharide also has good bacteriostatic activity, and especially has a remarkable inhibition effect on the growth of
nocardia. Therefore, the exopolysaccharide prepared in the invention has good application potential and popularization prospect as a microecological preparation capable of resisting cancer and inhibiting
bacteria, and can provide scientific research reference basis for research and development of environment-friendly marine biological preparations.
