Abstract  

Single factor test and response surface analysis were used for optimization of Ganodetma lucidum-Astragalus membranaceus polysaccharide solid fermentation. Optimized solid fermentation conditions were as follows: herbs solid fermentation medium, initial pH6.5, inoculum volume 10.16ml/100g, fermentation temperature 30.65℃, relative humidity 59.54%, fermentation period 28d. Under the above optimum conditions, Ganodetma lucidum-Astragalus membranaceus polysaccharide(GAPS) content was up to 9.12 ± 0.09mg/g and increased by 13.15% than unoptimization(8.06±0.07 mg/g), which provided a theoretical experimental basis for pharmacodynamics research and industrialization development.
