【Abstract】 Microbially converted caol products were added to the medium for culture and fermentation of microorganism to produce pigments. The pigments producing strains used in the experiment are Monascus anka and Phaffia rhodozyma. The absorbance of fermentation solution freed of biomass at 456 nm which represents the peak absorption of pigment increases greatly for the presence and the stimulating effect of microbially converted coal product in the culture, compared with that of the control tests, when the content of bioconverted coal product (BP) ranges from 60×10 -6 to 220×10 -6 . This result demonstrates the promising future of BP application in bioengineering and biological industry. Growth of vegetables in laboratory watered with BP containing solution ranging from 15×10 -6 ￣35×10 -6 also shows a 2 to 6 folds’ increase in the average weight of each piece of Chinese cabbage. The results reveal an important application prospect of BP as hormone material.更多还原
