南丰蜜桔可溶性固形物近红外特征波段选择（Selection of NIR Characteristic Wavelength Bands for Soluble Solids Content in Nanfeng Mandarin Fruit）
南丰蜜桔 可溶性固形物 近红外光谱 间隔偏最小二乘法
2009/8/11
探讨了在350～1800nm波段范围内不同光谱预处理方法对提高模型预测能力和稳定性的作用，但其效果不如间隔偏最小二乘法显著。通过间隔偏最小二乘特征波段选择方法，确定了南丰蜜桔可溶性固形物特征波段为：642～787nm、861～1006nm、1080～1152nm和1226～1371nm。采用30个未参与建模的南丰蜜桔样品，预测特征波段建模模型，预测模型的相关系数为0.95，预测均方根误差为0.55...
Selection of a Culture Medium for Reducing Costs and Enhancing Biomass and Intracellular Polysaccharide Production by Agaricus blazei AB2003
Agaricus blazei intracellular polysaccharide mycelial growth
2009/8/10
A practical medium for reducing costs and enhancing both biomass and intracellular polysaccharide (IPS) production by a newly screened Agaricus blazei AB2003 has been selected. The results show that I...
Selection of Co-Substrate and Aeration Conditions for Vanillin Production by Escherichia coli JM109/pBB1
Escherichia coli vanillin ferulic acid
2009/3/17
Yeast extract, Luria-Bertani medium and tryptone were tested as co-substrates for vanillin production from ferulic acid by resting cells of Escherichia coli JM109/pBB1. Yeast extract proved to be the ...
Selection of Aroma Components to Predict Sensory Quality of Kenyan Black Teas Using a Genetic Algorithm for Multiple Linear Regression Models
black tea aroma genetic algorithm multiple regression analysis
2010/11/22
A genetic algorithm (GA) was applied to optimizing sets of aroma components in black teas for calculating multiple linear regression (MLR) models to predict sensory scores. Selections of components we...
