胡萝卜素

As the main diagnostic carotenoids in Western Xiamen Bay and Jiulong River Estuary, fucoxanthin and peridinin showed the fact that diatoms were dominant contributor to spring bloom, while dinoflagellates preferred to grow in hot season.

厦门西海域主要特征类胡萝卜素为岩藻黄素，多甲藻素，玉米黄素，紫黄素和硅甲藻黄素。

Recent research shows that 5 gram of Young Barley Grass Powder contains equivalent amount of dietary fibre to 170 gram of apple or 270 gram of vegetable; equivalent amount of calcium to 400 ml of bovine milk; equivalent amount of iron to 35 gram of spinach and equivalent amount of carotene and vitamins to 170 gram of tomato.

最新科学研究发现，每5克的大麦嫩芽粉中，膳食纤维相当于170克苹果或270克青菜，含钙相当于400ml牛奶，含铁相当于35克菠菜，胡萝卜素和维生素相当于170克西红柿。

But Guarnieri suspects that the phytochemicals found in oranges (cyanidin-3-glucoside, flaanones and carotenoids) are the substances that need further study.

但是Guarnieri则认为是橙子中的花青素-3-葡萄糖苷，二氢黄酮和类胡萝卜素是需要进行深入研究的物质。

Although nothing to boast about, but the nutritional value than white sugar, sugar is much higher hectogram 90 mg of calcium, iron 4 mg, are white sugar, sugar, 3 times, but also contains small amounts of riboflavin (vitamin B2), and carotene.

虽然其貌不扬，但比白糖的营养价值，糖要高得多每百克90毫克的钙，铁4毫克，是白糖，糖，3次，而且还含有核黄素（维生素B2少量），和胡萝卜素。

Comparing 20 strains of the PSB in the study, R. azotoformans Y6 was chosen for producing the most lycopene output, which is 8.02×10~(-3) mg/L. Then the effects of pyridine, Triton-x100 Span-20,β-ionone, Isonicotinic acid hydrazide was studied.

利用上述获得的光合细菌类胡萝卜素提取方法和检测方法，对实验室保存的光合细菌菌株产生番茄红素能力进行了比较，得到了番茄红素产生量较高的菌株R.azotoformans Y6，其番茄红素产量为8.02×10~(-3)mg／L。

Romaine lettuce, for example has about six times as much vitamin C and eight times as much beta carotene as iceberg lettuce

例如，长叶莴苣含有的维生素C和β胡萝卜素。就分别是白莴苣中含量的6倍和8倍。

Lutein and zeaxanthin are both dihydroxy-carotenoids with the ionone ring systems distributed widely in nature.

叶黄素和玉米黄质是含紫罗酮环的二羟基类胡萝卜素，在自然界广泛存在。

Lutein is dihydroxy-carotenoids with the ionone ring systems distributed widely in nature as well as the main component of the retina macular pigment in human eye.

叶黄素是自然界广泛存在的含紫罗酮环的二羟基类胡萝卜素，也是人眼视网膜黄斑色素主要组成部分。

It was known that pyridine and Triton-x100 had a bad effect on the cell growth and lycopene production were studied. The results indicated that pyridine and triton-x100 inhibited cell growth and lycopene synthesis;β-ionone increased cell growth and lycopene synthesis when the concentration was 0.05 ml/L, but when the concentration became higher, there would be a decrease on the lycopene output; span-20 increased cell growth and lycopene synthesis effectively when the concentration reached 2.0ml/L, and the lycopene yield became 2.4×10~(-2) mg/L which was 3-fold than control.

研究了培养基中加入不同浓度的小分子效应物吡啶、Triton-x100、Span-20、β-紫罗酮、异烟肼对番茄红素产量的提高作用，结果显示培养基中加入很低浓度的吡啶(0.1ml／L)就会对菌体产生很强的毒害作用；triton-x100对类胡萝卜素的合成也有很强的抑制作用，试验的浓度为0.2ml／L到5ml／L，结果发现它对菌体的生长和番茄红素的合成都有抑制作用；β-紫罗酮在浓度为0.05ml／L时有很小的促进作用，而浓度升高就有了比较强的抑制效果；span-20在液体培养基中的加量为2.0ml／L时，对番茄红素的合成有很强的促进效果，产量达到了2.4×10~(-2)mg／L，比原始菌株产量提高了2倍，而浓度进一步增大就产生了很强的抑制效果。

As shown by the result, the biomass and astaxanthin content of oceanic red yeast was reduced due to the presence of β-ionone which inhibited the synthesis of carotenoids. The lethality rate of oceanic red yeast would attained 92.3% if 370 mg/L of the β-ionone concentration was contained in the plate medium. The oceanic red yeast mutated by ethyl methane sulfonate was cultured on plate medium containing 370 mg/L of the β-ionone. 200 mutants were randomly screened, positive mutants with increased the biomass, astaxanthin volumetric yield and astaxanthin specific yield accounted for 18% of the total strain, the mutants with higher biomass, astaxanthin volumetric yield and astaxanthin specific yield higher occupied 22.5%, 45% and 46%, respectively.

实验结果表明，在β-紫罗兰酮存在的情况下，由于类胡萝卜素合成受到抑制，海洋红酵母的生物量和虾青素合成量都减少；当平板培养基中β-紫罗兰酮浓度达到370 mg/L时，海洋红酵母的致死率为92.3%；在这种平板培养基上涂布经甲基磺酸乙酯诱变的海洋红酵母，随机筛选200个菌落，结果表明生物量、虾青素体积产率和细胞产率均有所提高的正突变株占18%，生物量、虾青素体积产率和细胞产率的单项指标有所提高的正突变株分别占22.5%、45%和46%。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
