用气液色谱法研究泥炭水解产物的有机酸植物原料水解产物含有有机酸,这些有机酸是半纤维素乙酰基团水解分离以及单糖类的分解转换而生成。泥炭水解时沥青和腐植物质的部分氧化也生成有机酸。有机酸由于是酵母碳的来源从而提高营养基的使用价值。我们的研究表明(见表11、12),泥炭浓硫酸水解所得水解产物中有机酸总含量占有机物质的15—20％,或占
Hydrocarbon chromatography of organic acids in peat hydrolyzate The hydrolyzate of the plant material contains organic acids which are formed by the hydrolysis and separation of hemicellulose acetyl groups and the decomposition and conversion of monosaccharides. Partial oxidation of bitumen and humic substances during peat hydrolysis also produces organic acids. Organic acids are used as a source of yeast carbon to increase the value of nutrition. Our research shows (see Table 11 and 12) that the total organic acids in the hydrolysates obtained from the hydrolysis of peat concentrated sulfuric acid make up 15-20% of the total organic material, or
