为了提高废弃西瓜皮的综合利用价值，减少环境污染，以废弃西瓜皮为原料，利用安琪饲料酵母固态发酵生成单细胞蛋白，以尿素添加量、初始 pH、菌种接种量、发酵时间为考察因素，以粗蛋白为指标，采用正交试验优化西瓜皮固态发酵工艺。结果表明：发酵的最佳组合条件为尿素2．0 g，菌种接种量7．5 mL，培养时间48 h，初始 pH5．0。在该条件下，单细胞蛋白由10．5％提高到25．6％，粗纤维由1．7％降低到0．5％，粗灰分由2．5％提高到7．1％。
為瞭提高廢棄西瓜皮的綜閤利用價值，減少環境汙染，以廢棄西瓜皮為原料，利用安琪飼料酵母固態髮酵生成單細胞蛋白，以尿素添加量、初始 pH、菌種接種量、髮酵時間為攷察因素，以粗蛋白為指標，採用正交試驗優化西瓜皮固態髮酵工藝。結果錶明：髮酵的最佳組閤條件為尿素2．0 g，菌種接種量7．5 mL，培養時間48 h，初始 pH5．0。在該條件下，單細胞蛋白由10．5％提高到25．6％，粗纖維由1．7％降低到0．5％，粗灰分由2．5％提高到7．1％。

To enhance the comprehensive utilization value of waste watermelon peel and reduce environmental pollution,taking waste watermelon peels as raw material,Anqi feeding yeasts were utilized for solid state fermentation in generating single-cell proteins.Crude proteins were utilized as indicators for the measurement of quality of product.The experiment studied influential factors included the addition volume of urea affecting single-cell protein production,original value of pH,volume of vaccinated strain, time consuming of fermentation and so on.Fermentation technology was further optimized by orthogonal test.As the results demonstrated,the optimum combination of the conditions was 2.0 g of urea,7.5 mL of vaccinated strain,48 hours of consumed fermentation and the original value of pH was 5.0.After the fermentation occurred,under the condition mentioned above,the product of crude protein was increased from 10.5% to 25.6%,crude fiber decreased from 1.7% to 0.5%,crude ash increased from 2.5% to 7.1%.
