Abstract
本发明涉及用于受到真菌毒素玉米赤霉烯酮污染的饲料产品解毒的方法。
Description
涉及序列表
本申请含有计算机可读形式的序列表。将所述计算机可读形式通过题述并入本文。
发明领域
本发明涉及解毒受到真菌毒素玉米赤霉烯酮(mycotoxin zearalenone)污染的饲料产品的方法。
发明背景
谷物上的几种植物致病性和/或收获后镰孢属菌种产生牲畜和家禽生产者相当关注的毒性物质,例如,脱氧瓜萎镰菌醇(deoxynivalenol)、T-2毒素、HT-2毒素、蛇形菌素(diacetoxyscirpenol)和玉米赤霉烯酮。
玉米赤霉烯酮存在于世界范围的多种谷类作物中,如玉米、大麦、燕麦、小麦、黑麦、稻、黍和高粱。在收获前玉米赤霉烯酮的产生似乎不以显著的量发生,但在合适的环境条件下,其易在储藏中的玉米和小谷粒上产生。
当在乙醇生产中使用谷物颗粒并消耗淀粉时,玉米赤霉烯酮集中在发酵副产品(例如,蒸馏干酒糟(distiller’s dried grain))中。发酵副产品中的玉米赤霉烯酮含量可能相对于谷物颗粒增加为三倍。
所述毒素是热稳定的,并且不因长期储存、烘烤或因丙酸或霉菌生长延缓剂的加入而受到破坏。
尽管它们与甾族雌激素在结构上不相似,但是玉米赤霉烯酮及其几种衍生物具有雌激素活性。玉米赤霉烯酮经过折叠使得羟基或潜在的羟基变成合适的朝向以促进与通常结合雌激素的组织受体结合。
玉米赤霉烯酮是引起不育、败育或其它繁殖问题的主要毒素,特别是在猪中。所述症状在青春期前的小母猪(prepubertal gilt)中尤其严重,包括乳房增大、子宫和阴门肿胀和卵巢萎缩。在严重的情况中,可能发生阴门和直肠下垂。公猪展现出乳房增大和睾丸下垂。
玉米赤霉烯酮存在于来自用受污染的谷物喂养的动物的肉中,以及从受污染的小麦焙烤的面包中。尽管人中毒的情况罕见,但是存在对于人长期曝露于这种雌激素活性的结果的关注。
使用环氧酶或内酯酶失活真菌毒素(包括玉米赤霉烯酮)在WO9612414中公开。
需要进一步的解毒受到真菌毒素玉米赤霉烯酮污染的动物饲料产品的方法,所述产品例如,如发酵副产品,包括蒸馏湿酒糟和干酒糟。
发明内容
本发明的发明人发现了饲料产品中的真菌毒素能够通过用漆酶处理所述饲料产品而降解成无毒物质。因此,在第一个方面本发明提供用于降解饲料产品中真菌毒素的方法,所述方法包括用漆酶处理所述饲料产品。所述真菌毒素优选是玉米赤霉烯酮。
在第二个方面本发明提供漆酶用于降解真菌毒素的用途。
发明详述
玉米赤霉烯酮
在本发明的上下文中,术语“玉米赤霉烯酮”包括自某些镰孢属菌种(Fusarium sp.)产生的真菌毒素玉米赤霉烯酮。IUPAC名称为(4S,12E)-15,17-二羟基-4-甲基-3-氧杂二环[12.4.0]十八碳-12,15,17,19-四烯-2,8-二酮((4S,12E)-15,17-Dihydroxy-4-methyl-3-oxabicyclo[12.4.0]octadeca-12,15,17,19-tetraene-2,8-dione)。术语“玉米赤霉烯酮”还包括任何玉米赤霉烯酮的衍生物,其包含一个或多个对漆酶的修饰易感的羟基。
动物饲料产品
术语“动物”包括所有动物,包括人。动物的实例是牛(cattle),(包括但不限于乳牛/母牛(cow)和牛犊(calf));单胃动物,例如猪(pig or swine)(包括,但不限于,小猪(piglet)、饲育猪(growing pig)和母猪(sow));家禽如火鸡(turkey)和鸡(chicken)(包括但不限于雏鸡(broiler chick)、蛋鸡(layer));和鱼(包括但不限于鲑鱼(salmon))。
术语“饲料”或“饲料产品”意指任何适用于或意图用于由动物摄取的化合物、制备物、混合物或组合物。
所述饲料产品可以是与不想要的水平的玉米赤霉烯酮分离的产品,其适合于由动物食用(consumption)。所述饲料产品也可以是疑似包含不想要的水平的玉米赤霉烯酮的产品,和/或玉米赤霉烯酮水平未知的产品,包括不包含可检测水平的玉米赤霉烯酮的产品。
所述饲料产品优选是基于谷粒的产品。所述基于谷粒的产品优选包含谷物,例如,玉米、小麦、大麦、黑麦、稻、高粱和黍中的一种或多种。在一个实施方案中,所述饲料产物可以例如仅源自一种或多种谷物,而在另一个实施方案中部分源自豆类(例如源自大豆)且部分源自谷物。所述基于谷粒的产品可以包含完整的或研磨的谷粒,例如,湿磨或干磨的谷粒,包括包含湿磨或干磨谷粒的级分的基于谷粒的产品,所述级分例如,谷蛋白、蛋白质、淀粉和/或油级分。还优选包含来自酿造和/或发酵过程的副产品(例如,酒糟(spent grain))的产品。酒糟是来自酒精饮料和乙醇燃料生产的副产品。啤酒酒糟(brewers’spent grain)(BSG)是酿酒厂中啤酒酿造的残余物,这种酿酒厂使用发芽大麦作为主要原料。蒸馏酒糟(distiller’s spent grain)(DSG)是在从发酵的谷粒如玉米、小麦、大麦、稻和黑麦通过蒸馏去除醇之后在蒸馏室(distillery)中剩余的产品。蒸馏酒糟也称作酒糟(distiller’s grain)。将湿酒糟(WDG)干燥产生干酒糟(DDG),其主要用作动物饲料。
漆酶
在本发明的上下文中,术语“漆酶”包括由酶类别E.C.1.10.3.2所包含的酶。
优选下述的酶,特别是重组的和/或基本上纯化的酶。

漆酶也可以源自真菌如金钱菌属(Collybia)、层孔菌属(Fomes)、香菇属(Lentinus)、侧耳属(Pleurotus)、曲霉属(Aspergillus)、脉孢菌属(Neurospora)、柄壳孢属(Podospora)、射脉菌属(Phlebia)(例如辐射射脉菌(P.radiate)(WO92/01046))、革盖菌属菌种(Coriolus sp.)(例如毛革盖菌(C.hirsitus)(JP2-238885))、或葡萄孢属(Botrytis)。
在优选的实施方案中,漆酶是来自嗜热毁丝霉(Myceliophthorathermophila)(MtL)的、具有作为GENESEQP:AAR88500保藏并在本文作为SEQ ID NO:1显示的氨基酸序列的漆酶,来自Polyporus pinsitus(PpL)的、具有作为UNIPROT:Q99044保藏并在本文作为SEQ ID NO:2显示的氨基酸序列的漆酶,来自天蓝色链霉菌(Streptomyces coelicolor)ScL的、具有作为SWISSPROT:Q9XAL8保藏并在本文作为SEQ ID NO:3显示的氨基酸序列的漆酶,或具有与这些序列中的任一同源的氨基酸序列的漆酶。
漆酶必需以有效量存在于要解毒的介质中。漆酶优选以0.01-100mg酶蛋白每kg干物质,优选0.1-10mg酶蛋白每kg干物质,或更优选1-5mg酶蛋白每kg干物质的浓度存在。
介体(mediator)
在一个实施方案中,将充当供漆酶用的电子供体的介体与漆酶一起使用。所述介体应该以有效量存在于要解毒的介质中。
已知多种介体;参见例如WO9412620、WO9412621、WO9501626、WO9600179和WO9923887。将其中的介体通过提述并入本文。

所述介体是商业上可获得的或能够通过本领域已知方法制备的。
介质(medium)
在一个实施方案中,漆酶降解包含饲料产品的介质中的玉米赤霉烯酮。所述介质优选是水性的并且可以是液体、糊剂(paste)或浆。为了形成合适的介质,可以向饲料产品加入水。漆酶和介体可以单独或一起包含在适合施用于所述介质的固态或液态配制剂中。
在一个实施方案中,漆酶以某种程度降解玉米赤霉烯酮,由此使每kg干物质饲料产品的玉米赤霉烯酮含量降低至低于初始量的50%、低于60%、低于70%、优选低于80%、更优选低于85%、还更优选低于90%、和最优选低于95%。
本发明的解毒效力依赖于例如介质的氧的可用性、pH、温度和缓冲液。例如,处理可以在实际漆酶(actual laccase)的相对活性为至少50、或60、或70、或80或90%的pH值进行。同样,例如,处理可以在实际漆酶的相对活性为至少50、或60、或70、或80或90%的温度进行。相对活性是相对于观察到最高活性的pH值的活性计算的。
介质中的氧
漆酶所需的氧的来源可以是来自大气的氧或用于原位产生氧的氧前体。来自大气的氧会通常以充足的量存在。如果需要更多的O2,可以加入额外的氧,例如,作为加压的大气或作为加压的纯氧。
介质中的pH
依赖于漆酶的特征和所用的介体等,所用介质的pH应通常在5-11的范围,优选在6-10的范围,例如6.5-8.5。
介质中的温度
优选使用接近于用于漆酶的最适温度的反应温度。在本发明的多个实施方案中,应使用范围在10-65℃,更优选30-50℃的温度。
处理持续时间
处理的持续时间依赖于处理类型、要处理的对象(item)的类型、介质的性质(例如温度和pH)和所用的酶和介体的类型和量等。
酶反应不断进行直到达到期望的结果,其后可以可以或可以不通过使酶失活(例如,通过热处理步骤)终止所述酶反应。
为了解毒的目的,可以使用范围在1分钟至1周的处理时间。在许多情况下,范围在6-48小时的处理时间将是合适的。
