本发明公开了菌株CH18在制备花青素与其它黄酮类化合物中的应用。所述菌株CH18的保藏号为CGMCC NO.14784。黄酮类化合物具有抗氧化、抗肿瘤、抗疲劳、延缓衰老、预防心脑血管疾病、降血压、降血脂、调节神经内分泌、抗骨质疏松症、祛斑抗皱、明目等作用。现有技术中的花青素等黄酮类化合物主要是从植物中获得,植物原料供给受季节性限制,且栽培需要占用大量的农田。本发明利用微生物生产花青素和其它黄酮物质具有廉价、易控制、生产周期短、可周年生产的优势,能够满足工业化生产的需要。因此,本发明为高效、低成本生产多种花青素与其它黄酮类化合物开辟了一条新的生物途径。

Description

菌株CH18在制备花青素与其它黄酮类化合物中的应用
技术领域
本发明属于微生物资源开发与利用技术领域,具体涉及菌株CH18在制备花青素与其它黄酮类化合物中的应用。
背景技术
花青素(anthocyanins)是一类重要的黄酮类化合物,是构成花朵和果实颜色的主要色素之一。根据其结构不同,可将植物中常见的花青素分为矢车菊色素、天竺葵色素、飞燕草色素、芍药色素、矮牵牛色素和锦葵色素等6类。黄酮类化合物是指以2-苯基色原酮为母核的一系列多酚类化合物,属于植物次生代谢产物。除花青素之外,黄酮类还包括黄酮醇、异黄酮、黄酮类、黄烷酮、查尔酮、双氢黄酮(醇)等不同类别物质。植物中黄酮类物质多以苷类形式存在,黄酮苷因所带羟基数、甲基化、乙酰化、糖基化数目、糖种类和连接位置等因素不同,形成种类繁多的黄酮苷类物质。现已查明在可食用的植物食品中有5000多种黄酮类化合物。不同植物来源的黄酮组分不同。
黄酮类化合物具有多种生物活性,如抗疲劳、抗菌、抗病毒、抗肿瘤、抗氧化自由基、抗炎、镇痛、保护肝脏、预防心脑血管疾病、降血压、降血脂、调节神经内分泌、抗骨质疏松症、祛斑抗皱、明目、提高机体免疫力、镇咳、祛痰、解痉等药理活性。
目前,花青素等黄酮类化合物主要来源于植物。植物生产周期长,且受环境、产地和原料供给季节性强等多重因素影响。与植物相比较,利用微生物生产花青素等黄酮类物质,具有生产周期短、低耗、高效、且可全年生产等优点,可满足工业化生产的需要,应用前景广阔。本发明筛选得到的菌株能够合成多种花青素和其它黄酮类化合物,为花青素等黄酮类化合物的生产开辟了一条生物新途径。

实施例4菌株CH18产花青素等黄酮类物质呈色与抗氧化性
1、菌株CH18产花青素类色素物质
将菌株CH18发酵液pH值分别调成pH2、3、4、5、6、7、8、9、10、11,发酵液呈现出不同颜色,见附图5,在酸性条件下为红色、碱性条件为蓝色到兰灰色。菌株CH18花青素作为呈色物质,可应用于与水质测定、体液测定、酸碱指示显色剂、食品、保健品、化妆品等领域。
在色素方面,随着人工合成色素大量使用引起的一系列环境和健康问题,增加了人们对天然色素的需求。天然色素主要来源于植物和微生物,植物生长周期长,在大规模应用中受限。与植物源天然色素相比,微生物源色素,例如CH18产生的花青素类色素,易于大规模快速发酵生产,具有广阔的应用前景。
2、菌株CH18产黄酮类物质的抗氧化性与稳定性测定
1)菌株CH18产黄酮类物质的抗氧化性
菌株CH18产黄酮类物质对DPPH自由基清除效果的测定:
取2mL菌株CH18提取液于试管中,加入0.25mmo l/L的1,1-二苯基-2-三硝基苯肼(DPPH)乙醇溶液2mL,混匀。室温静置30mi n,于517nm波长处测量吸光度,记为A1;取2mL菌株CH18提取液与2mL无水乙醇混合均匀,测量吸光度,记为A2;取2mL DPPH乙醇溶液与2mL无水乙醇溶液混合均匀,测量吸光度,记为A3。用维生素C(Vc)作为阳性对照。菌株CH18黄酮物质对DPPH自由基的清除率计算公式如下:
DPPH清除率(%)=[1-(A1-A2)÷A3]×100
研究发现,在VC添加量为0.08mg/ml和0.18mg/ml条件下,菌株CH18提取液中黄酮物质对DPPH除率率分别高于Vc溶液7.1%和5.5%。显示菌株CH18提取液对DPPH自由基具有较高的清除能力和抗氧化活性,可应用于食品、药品、保健品、化妆品等领域,也可作为抗氧化剂应用。
2)菌株CH18产花青素类物质的稳定性
a)光照与黑暗对稳定性影响
在室温(20℃-37℃)条件下,比较光照与黑暗对菌株CH18产花青素类物质稳定性影响。根据菌株CH18花青素类物质在505nm有吸收峰特点,测定菌株CH18花青素液在OD505变化值,判断其稳定性。测定结果见附图6。研究发现菌株CH18产花青素类物质在光、暗条件下稳定性均较好。可在自然光照条件下和黑暗条件下应用和保存。
b)金属离子对稳定性影响
在菌株CH18花青素提取液中添加Ca2+、Na+、K+、Mg2+、Fe+和Fe3+盐,放在冰箱5℃条件下,观测溶液OD505值及溶液颜色变化。测定结果见附图7,结果显示,添加金属离子Ca2+、Na+、Mg2+、Fe+和Fe3+离子实验组,其溶液OD505值等于或高于对照组,可见上述金属离子添加不会影响CH18花青素稳定性,有的还可提高花青素的稳定性。因此,菌株CH18花青素添加到含有上述金属的食品、保健品、药品、水体、化妆品及其它产品中,花青素的稳定性好。

1、食品、药品、保健品

2)保健品、药品领域应用
菌株CH18合成花青素和其它黄酮类产物具有高的抗氧化性、稳定性和生物活性,可以应用于保健品、药品生产。
2、酸碱指示显色剂、天然色素和抗氧化剂应用
花青素在较宽的pH范围内均能保持鲜艳的红色、紫色或蓝色,且在酸性条件下具有良好的热稳定性,加之具有较强的抗氧化活性,作为天然色素、显色剂、酸碱指示剂、抗氧化剂应用于食品、保健品、化妆品、水质检测、日用品、化工等行业。
