油脂

The ordinary causes are too much hormone formed during puberty, too excessive lipa, fatty acid, which cause the block of the sebaceous glands, indigestion and habitual constipation; using high-lipa cosmetics, not noticing personal hygiene.

常见的是青春期激素生成量过多，产生过量的油脂、脂肪酸，造成皮脂腺阻塞；消化不良，习惯性便秘；使用油脂过高的化妆品；不注意个人清洁卫生；空气污染；心情紧张压力大等多种情况都会造成青春痘的产生。

This paper focuses on the stability study of Rhizopus oryzae IFO4697 when used for the methanolysis of renewable oils for biodiesel production. The results showed that water content was important for achieving high catalytic activity and good stability of the biocatalyst. The optimum water content was found to be 5%-15%. Both particle size and desiccation methods showed no obvious effect on the stability of the biocatalyst. With GA cross-linking pretreatment, the stability of the biocatalyst could be improved significantly. When Rhizopus oryzae IFO4697 repeatedly used for next batch reaction, direct vacuum filtration was found to be a good way for the maintenance of good stability of the biocatalyst.

本实验对固定化全细胞Rhizopus oryzae IFO4697催化植物油脂合成生物柴油的稳定性进行了系统地研究，结果表明：反应体系水含量对于全细胞催化剂的反应活性和催化稳定性有重要影响， 5%~15%含水量适宜；研究范围内，载体粒度及干燥方式对稳定性影响不显著；经过戊二醛交联后，全细胞催化油脂甲醇解反应的稳定性显著提高， 1200 h反应后，仍然可以保持75%的生物柴油得率；真空抽滤直接回用的方式有利于稳定性的保持。

The oil was further explored for biodiesel production by lipase-catalyzed methanolysis. Two processes were studied, namely, three-step methanol loading in solvent-free system and all-in-one methanol loading in tert-butanol system.

进一步利用该酵母油脂为原料分别研究了无溶剂体系中三步甲醇法及在叔丁醇介质体系中脂肪酶催化合成生物柴油，发现脂肪酶可以有效转化该酵母油脂制备生物柴油。

Enriched with active ingredients which will normaliza sebaceous secretion,make the skin refresh and nongreasy to minimize the ance occurring.

高效能的天然活性精华，专门针对油脂、暗疮皮肤而设。滋润保湿不油腻，特效的去油因子能有效的控制油脂分泌。

Such oils as soybean oil, cottonseed oil, and olive oil are of plant origin, lard and tallow are examples of nonliquid fats from animals, yet fat from the horse is liquid at ambient temperatures and is referred to as horse oil.

豆油、棉籽油、橄榄油等都是来自植物的油。猪油和牛、羊脂是典型来自动物的固态油脂。不过，来源于马的油脂在室温下是液态的，故称之为马油。

Such oils as soybean oil, cotto eed oil, and olive oil are of plant origin, lard and tallow are examples of nonliquid fats from animals, yet fat from the horse is liquid at ambient temperatures and is referred to as horse oil.

A saturated fatty acid; glycerides of palmitic acid occur widely in plant and animal oils and fats.

一种饱和脂肪酸，广泛存在于植物和动物油脂和脂肪中的棕榈酸甘油脂。

Palmitoleic acid is 52.14% of total oil and fat. According to the results of identification, the strain is considered of belong to species Saccharomyces cerevisiae.

该菌株产油脂量为菌体干重的32.06％，棕榈油酸占油脂总量的52.14％，经初步鉴定认为是一株酿酒酵母Saccharomyces cerevisiae。

By 16S rRNA. When it was cultured in MMSW substrate, adding MWFO and SWFO as the carbon source, it could produce crude biodemulsifier of 4 g/L and 3.5 g/L respectively. Compared with biodemulsifier produced by paraffine as the carbon source, both of them could achieve higher demulsification ratio in breaking W/O and O/W model emulsion.

的一株破乳剂产生菌，在以废弃油脂MWFO、SWFO为碳源培养下，得到的生物破乳剂的粗重为4 g/L、3.5 g/L；对于W/O、O/W模型乳状液的破乳效果均可超过以液体石蜡产生的破乳剂，且以SWFO废弃油脂培养得到的生物破乳剂可以同时应用于两种模型乳状液的使用。

The analysis of correlation between ratio of different parts and their oil content s of Sapium sebiferum seed and environmental factors

我国油菜品种油脂含量普遍较国外低2-5个百分点，而油脂含量每增加1个百分点对产油量提高的贡献，相当于菜籽产量提高2。
