An attempt was made to compare the biological value of the biological mass of the hydrogen bacteria Tydrogenomas eutropha, of meat and wheat on the ground of the fractional and amino acids composition of their proteins. Substantial differences in the distribution of proteins and amino acids in all of the three objects examined were revealed. It is shown that more than one half of the entire protein contained in the biological mass of the hydrogen bacteria is made up of poorly soluble structural proteins difficultly amenable to the action of digestive enzymes. It is this fraction where the bulk of essential amino acids is concentrated. The data obtained imply that the biological value of the biological mass of hydrogen bacteria is higher than in wheat, but lower than in meat.
基于蛋白质的分级和氨基酸组成,对嗜糖假单胞菌(Tydrogenomas eutropha)这种氢细菌、肉类和小麦的生物质的生物学价值进行了比较。在所检测的所有三个对象中,蛋白质和氨基酸的分布存在显著差异。结果表明,氢细菌生物质中所含的全部蛋白质的一半以上是由难溶性结构蛋白组成,这些蛋白很难被消化酶作用。正是在这一部分中,大量必需氨基酸得以浓缩。所得数据表明,氢细菌生物质的生物学价值高于小麦,但低于肉类。
