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.

Mol/m2s low light treament cause leaf-upgrowth stopping, flower withering and losing fruit-settle capability. Fruit-settle efficiency enhance in 400μmol/m2s low light maybe because high light's injury on flowers are reducing. 200μmol/m2s and 80μmol/m2s low light treament cause carborhybrate synthesis decreasing, prevent carborhybrate's transforming to flower, lead to fruit-settle efficiency reducing. 30μmol/m2s low light is close to light compensation point of peach tree, which cause nutrition lackness, lead to peach tree's mechanism declining eventually.

表明400μmol/m2s的弱光提高花朵向幼果的转化可能是400μmol/m2s的弱光减弱了强光对花器的伤害的原因。200μmol/m2s和80μmol/m2s的弱光下，叶片合成的碳水化合物减少，向生殖器官的运转受到抑制，分配量减少，生殖生长减慢，落花延迟且花朵向幼果的转化率下降；30μmol/m2s的弱光已接近光补偿点，导致桃树营养缺乏，株体机能降低。
