         The effects of the different methods of treatment of anatase titanium dioxide and the relative amouuts of SiO_2, Al_2O_3 and Mn_3(PO_4)_2 in the mixture with which it had been treated on its properties were studied. In basic aqueous medium of pH≥7, the mixture of SiO_2, Al_2O_3 and Mn_3 (PO_4)_2 was precipitated on TiO_2, giving a light resistant pigment which had high dispersity in both water and caprolactam and was capable of delustering polyamide fibers.

         Skim serum is an industrial effluent from rubber factories. It is of higher BOD and contains about 1% protein and 0.05-0.3% ammoniacal nitrogen, etc. The effluent was used to culture Geotrichum candidum as SCP(single-cell protein) feed, thus reducing environmental pollution. This paper describes the optimum technical conditions for culturing Geotrichum candidum with skim serum effluent.The experiments were carried out on a multifactorial and orthogonal design. The results showed that, among the four strains...
            胶清废水系天然橡胶初加工时的一种工业废水,具有较高的生化需氧量(BOD),其中约含有1%蛋白质,0.05~0.3%氨态氮等。我们曾利用这种废水培养白地霉(Geotrichum candidum)作为单细胞蛋白饲料,从而减少对环境污染。本文叙述了利用胶清废水培养白地霉的最适工艺条件。试验采用多因子正交设计法。试验结果表明:在采用的四个菌株中以顺糖2号自地霉的容积生产效率(VPE)最高,在培养基中仅需添加1~1.5%的碳源,该菌株在胶清废水中就能良好生长,干菌体产量达1.52%。此外,耗糖少(菌体与还原糖之比为1:0.6),残糖低(0.1%以下)。试验表明,最适培养条件是:糖蜜作碳源、碳氮比10:1,通气量(V/V)1:1,pH值5.5,发酵时间9~10小时,温度29~31℃,搅拌速度450转/分等。其菌体含粗蛋白质53.85%,脂肪3.65%,核酸6.34%,并含有18种氨基酸,具有赖氨酸等8种营养必需的氨基酸,和乙族维生素等,黄曲霉毒素B_1<5 ppb。所得菌体营养丰富,不仅供作禽畜的单细胞蛋白质饲料,并可抽提核酸,同时可减少胶清废水的生化需氧量(BOD)。
