  • 沸点:
    444.6 °C
  • 密度:
    2.1 g/cm3
  • 物理描述:
    Sulfur, molten appears as a pale yellow crystalline solid with a faint odor of rotten eggs. Insoluble in water. A fire and explosion risk above 450° F. Transported as a yellow to red liquid. Handled at elevated temperature (typically 290°F) to prevent solidification and makes transfers easier. Hot enough that plastic or rubber may melt or lose strength. Causes thermal burns to skin on contact. Cools rapidly and solidifies if released. Equipment designed to protect against ordinary chemical exposure is ineffective against the thermal hazard. Exercise caution walking on the surface of a spill to avoid breakthrough into pockets of molten sulfur below the crust. Do not attempt to remove sulfur impregnated clothing because of the danger of tearing flesh if a burn has resulted. May be irritatin to skin, eyes and mucous membranes. Used in sulfuric acid production, petroleum refining, and pulp and paper manufacturing.

毒理性
  • 在妊娠和哺乳期间的影响
◉ 母乳喂养期间使用总结:含5%至10%硫磺的凡士林基质对儿童(包括2个月以下的婴儿)局部使用是安全的。[1]这使得它成为治疗哺乳期母亲疥疮的有机杀虫剂的有用替代品;然而,凡士林基质使其不适宜用于乳房。 ◉ 对哺乳婴儿的影响:截至修订日期,未找到相关已发布信息。 ◉ 对泌乳和母乳的影响:截至修订日期,未找到相关已发布信息。
◉ Summary of Use during Lactation:Sulfur 5% to 10% in a petrolatum base is safe for topical use in children, including infants under 2 months of age.[1] This makes it a useful alternative to organic insecticides for treating scabies in nursing mothers; however, the petrolatum base makes undesirable for use on the breast. ◉ Effects in Breastfed Infants:Relevant published information was not found as of the revision date. ◉ Effects on Lactation and Breastmilk:Relevant published information was not found as of the revision date.

    摘要:
    摘要 嗜热古菌 嗜热古菌 以碳水化合物为碳源,产生醋酸盐、CO 2 和 H 2 作为最终产物。当 S 0 加入生长中的培养物时,10 分钟内 H 2 产生的速率迅速降低,H 2 S 检测到。1 小时后,细胞中含有大量依赖于 NADPH 和辅酶 A 的 S 0 还原活性(0.7 单位/毫克,85°C)。负责这种活性的酶已被纯化至电泳均一性(特异性活性为 100 单位/毫克),并被称为 NAD(P)H 元素硫氧化还原酶(NSR)。NSR 是一种同源二聚体黄蛋白(M M r 100,000),由 PF1186 编码。这一名称以前是分配给编码一种还原辅酶 A 二硫化物的酶的基因的,该酶是 NSR 的一个副反应。全基因组 DNA 微阵列和定量 PCR 分析表明,在 S 0 添加的 10 分钟内,NSR 的表达上调达 7 倍。这种对 S 0 的主要反应还包括编码膜结合氧化还原酶(MBX)的 13 个基因簇的上调(16 倍)。据推测,编码 MBX 的基因簇将取代同源的 14 个基因簇,后者编码铁氧还蛋白氧化酶、H 2 -膜结合氢化酶(MBH)的同源 14 个基因簇。 0 下调 12 倍。虽然 MBX 的活性尚未得到证实,但有人认为它可以通过氧化铁氧还原 NADP 来保存能量,NADP 被 NSR 用来还原 S 0 .对 S 0 的次级反应。 0 包括编码参与氨基酸生物合成和铁代谢的蛋白质的基因上调,以及两种称为 SipA 和 SipB 的所谓硫诱导蛋白。这种新型 S 0 -还原系统迄今只在异养型 热球菌 与基于细胞色素和醌的 S 0 -还原系统相反。
