The pathogen grew well on the media using glucose, sucrose, fructose, maltose, rhamnose or soluble starch as carbon sources. Galactose, xylose, mannite or sorbose was not beneficial for the growth of the pathogen, however. The media with only organic or inorganic nitrogen sources were not suitable for the pathogen growth although organic nitrogen sources were better than inorganic nitrogen sources. The pathogen could also infect Allium cepa L., A. fistulosum L. and A. odorum L. under artificial inoculation conditions.

C. gloeosporioides mycelium grew well on media with fructose and glucose as carbon source while sorbose and starch promoted sporulation. The mycelia of C. dematium grew well with maltose as carbon source while starch promoted sporulation. Of the nitrogen sources tested, organic nitrogens were beneficial for both mycelial growth and sporulation but chemical nitrogens suppressed both growth and sporulation.

The quality of purified 2-KGA from its fermentation products was up to industrial standard. In addition, several hexoses, such as D-glucose and D-sorbitol can be utilized to synthesize 2-KGA by this newly-mixed culture. The growth and anabolism of the B529-V6 were studied in 4M〓 and 300M〓 fermentor respectively. The results showed that its growth and anabolism were affected by carbon sources, ratio of D-glucose and L-sorbose, nitrogen sources, growth factors, inoculum quality and culture condition including the initial pH value, temperature and ventilation.
