Chemical and microbiological compositions of 12 samples of traditionally home-made koumiss in Xingjiang Uighur Autonomous Region were determined. The average contents of fat, protein, lactose, ash, calcium and phosphorus were 2.07g/100mL, 2.22g/100mL, 3.03g/100mL, 0.28g/100mL, 82.27mg/100mL and 58.20mg/100mL respectively. On average, pH was 3.90, titratableacidity was 134.25°T, lactic acid content was 10.99g/L, acetic acid content was 1.50g/L, citric acid content was 0.09g/L, ethanol content was 14.94g/L. The counts of lactic bacteria in 10 samples were 1.07~9.70×107cfu/mL, 1 sample was 1.38×108cfu/mL, another sample was 2.06×106cfu/mL; the counts of yeast in 1 samples was 3.20×104cfu/mL, 5 samples were 1.80~6.60×105cfu/mL, and 6 samples were 1.06~2.72×106cfu/mL. 33 strains isolated from 12 samples of traditionally home-made koumiss collected from Xingjiang Uighur Autonomous region belonged to Lactobacillus.

The two catalysts supported on USY zeolites with surface acid amounts of 626 and 203μmol/g, respectively, showed excellent sulfur tolerance, while the catalysts of higher and lower acid amount showed decreased sulfur tolerance. Energy dispersive spectroscopic analysis proved that the support with a large acid amount adsorbed more sulfur, which might lead to the lower sulfur tolerance of the catalyst.

结果表明硫含量为200μg/g时,载体酸量为626和203μmol/g的两个催化剂的耐硫性最好,而载体酸量更低和更高的催化剂的耐硫性较差,表明载体的酸量太大或太小都不利于催化剂的抗硫性。X射线能量散射分析表明,酸量大时S在酸性位吸附很多,这可能导致催化剂中毒。
