1.The nutrient content of yeast (Condida Y-17) grown on n-alkane studied in this experiment was comparable to that of the same type of yeast produced in other countries. Its content of lead, arsenic, mercury and benzo (a) pyrene were within the limit proposed by the Protein-Calorie Advisory Group of the United Nations System. The Content of its residual n-alkanes and total aromatic hydrocarbons were within or a little over that limit. It is a good supplementary protein feed.2.The corrected PER values were, yeast grown on n-alkane 1.18; deli pid and denucleic acid yeast grown on n-alkane 1.16; brewer's yeast 1.52; full fat soybean meal 1.81. The PER of yeast grown on n-alkane was significantly lower than those of other samples. When 0.3% DL-methionine was added to the diet, the corrected PER values increased: n-alkane grown yeast 2.32; delipid and denucleic acid n-alkane grown yeast 2.49; brewer's yeast 2.35; full fat soybean meal 2.28. The corrected PER value of casein used for correction was 2.43, it was standardized with ANRC reference protein (PER = 2.50).3.Yeast grown on n-alkane with and without removal of lipids and nucleic acid was fed to groups of rats at a dietary level of 25% and 35% respectively for 1 year. A stock diet group and a brewer's yeast diet group were used as control. In the first 3 months the weight gain and feed consumption of the rats fed n-alkanc grown yeast diet were lower than those of the two control groups. The male rats were more sensitive to the change of diet. In the later 9 months the difference of weight gain among different groups were not significant. The concentration of haemoglobin, red cell counts, white cell counts, GPTase activity, serum cholesterol levels and serum urea levels determined at the beginning and the end of the experiment were all in the normal ranges. The concentrations of n-alkanes and odd-chain fatty acids in the adipose tissue of the n-alkane grown yeast group were higher than those of the two control groups, and the difference was highly significant. The concentrations of total aromatic hydrocarbons and benzo(a) pyrene in the muscle of different groups of rats were 0.4-0.6 ppm and 0.4 ppb respectively. No detrimental effect was observed in pathological examination.4.When 5% fish meal or 3.5% casein was added to the 25% n-alkane grown yeast diet, the weight gain and feed consumption of weanling rats were improved significantly, though it was still inferior to those fed with stock diet.5.Strongly growth depressive effect was noted as the level of n-alkane grown yeast was increased to 20% in the diet. This depressive effect was neither due to the toxicity of the residual n-alkanes and aromatic hydrocarbons, nor due to the deficiencies of potassium and selenium in the diet. It might be the result of nutrient or nutrients imbalance of the diet. The appropriate amount of yeast grown on n-alkane used in mixed feed should not be more than 15%.

A convenient microbiological method with high accuracy for cystine assay was introduced. Common foods including cereals, beans, sweet potato, fishes and other aquatic products as well as meats were selected for cystine and methionine analysis. Based on the data obtained, a brief discussion was made on the way for resolution of sulfur amino acids problem inherently in our traditional soy-cereal based diet.

用改进的微生物分析方法测定了构成我国人民膳食的主要食物蛋白质中胱氨酸和蛋氨酸的含量。63种食物的测定结果表明,谷类、甜薯、猪肉和牛肉的蛋白质(按16g氮计)含硫氨基酸总量分别为4.10(3.42~4.47)%,4.19(3.66~4.72)%,3.68%和3.67%,达到和超过了FAO/WHO“参考蛋白”的含硫氨基酸总量(3.52%);鱼类和其他水产动物食品含量为3.32(2.68~3.71)%和3.24(2.52~3.69)%,略低于“参考蛋白”的含量;而黄豆及其他豆类和瓜籽的含硫氨基酸总量显著缺乏,分别为2.39(2.34~3.45)%,1.64(1.27~1.75)%和2.95(2.38~3.29)%,其中非黄豆豆类的含硫氨基酸总量,仅为“参考蛋白”的1/2弱。根据以往城市膳食调查资料,计算了我国人民膳食中含硫氨基酸的营养状况。指出:在我国城市居民通常的膳食中,含硫氨基酸的绝对摄入量已达到或超过Rose规定的适宜需要量。因此在豆类摄入比率不高的情况下,赖氨酸仍将是以谷物蛋白质为主的膳食蛋白质第一限制氨基酸。着豆类蛋白质的补充量较高,则应考虑到含硫氨基酸的摄入比率是否适...

Sixty Wistar rats were divided into 5 groups, 12 in each:1)Casein; 2) Fish powder (FP) ; 3) Fibrin; 4)Liver residue(LR) , 5)Nitrogen free(NF). The feeds for all groups of rats were at the level of 10% protein and at the same calories except NF. Growth test, nitrogen balance and recovery test were used and the levels of serum proteins and Hb were determined.The protein efficiency ratio (PER) of casein, FP, fibrin and LR were 1.90, 3.07, 2.61 and 1.28 respectively. Net protein ratio (NPR), apparent digestibility,...

Net protein ratio (NPR), apparent digestibility, true digestibility and net nitrogen ratio (NNR) were same as PER suggesting the protein quality of LR was low, FP was high and fibrin in the medium. The values of serum proteins also showed that 10% protein of LR could not maintain rats in health, but compared with casein and FP the nutritional quality of fibrin was high and could be used in feed industry or other products.The effects of proteins on hepatic microsomal enzyme were observed. The influence factors were discussed.

实验采用纯种Wistar大鼠,饲喂10%蛋白质水平的猪血纤维蛋白或肝渣蛋白质,以酪蛋白作为参考蛋白,并与普通饲料中主要的动物性蛋白质来源一鱼粉相比较。通过生长试验,氮代谢和恢复试验,观察到猪血纤维蛋白的营养价值较高,在某种程度上可与酪蛋白或鱼粉相比,可供进一步开发利用。而肝渣蛋白质的营养价值较低,仅能作饲料蛋白质的辅助来源。本实验还研究了不同蛋白质对大鼠肝微粒体混合功能氧化酶含量和活性的影响,并讨论了其意义。
