类胡萝卜素

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 concentration of pigments and other chemical components including anthocyanins,chlorophyll a,chlorophyll b,carotenoids,solubility sugar and 10 kinds of macroelement and microelement were investigated using P.virginiana Schubert',and calculated the relativity of the data.

本研究以紫叶稠李(Prunus virginiana'Schubert')为试材，对其不同叶位叶片进行花青苷、叶绿素a、叶绿素b、类胡萝卜素、可溶性糖及10种常量和微量元素的测定，并进行相关性分析。

For example red autumnal leaves is bright red broadleaf plant, red the flowers observing a part of a historical period such as back laurel, contain cyanine element inside their mesophyll cell, consequently the front of blade or the reverse side present red; The lamina that wait is in Gong Sang, nandina synthesis of the chlorophyll below weak light is much, kind of carotene falls in strong

例如红叶朱蕉。红背桂等观叶花卉，在它们的叶肉细胞内都含有花青素，因而叶片的正面或背面呈现红色；红桑。南天竹等的叶片在弱光下叶绿素合成多，在强光下类胡萝卜素合成多，故放在半阴处培养叶色发绿，放在强光下养护，则叶色发橙；金边吊兰。金边虎皮兰叶片的不同部位上细胞内分别含有叶绿素和叶黄素，所以叶片呈现出黄绿相间的两种颜色。

In order to clarify the physiological and biochemical basis of Nostoc commune lived in different environmental light levels, their daily changes of Fv/Fm, photosynthetic characteristics and content of carotenoids and chlorophyll were studied. Compared with shade-acclimated N.
