Abstract
本发明提供了一株具有甲胺降解能力的梭状芽孢杆菌及其应用。该菌株的名称为梭状芽孢杆菌(Lysinibacillus fusiformis)GDUTAN2,保藏在中国典型培养物保藏中心,保藏地址为湖北省武汉武汉大学校内;保藏编号为CCTCC NO:M 2017284,保藏日期为2017年5月24日。该梭状芽孢杆菌GDUTAN2革兰氏阳性,杆状,菌落形态为圆形,白色,透明,菌落直径为1~2mm。本发明的梭状芽孢杆菌GDUTAN2可应用于环境修复,降解环境中的甲胺,降解率高,在底物浓度为5mg/L条件下降解96h,降解率可达96.3%。
Description
技术领域
本发明属于微生物技术领域,更具体地,涉及一株具有甲胺降解能力的梭状芽孢杆菌及其应用。
背景技术
恶臭污染是当今空气污染的一大难题。有机恶臭气体主要分为含硫有机恶臭气体和含氮有机恶臭气体,其中甲胺(Methylamine,MA)是典型的含氮有机恶臭化合物。甲胺的嗅阈值低至0.021ppm,较难生化降解。在甲胺浓度较低时就可以产生强烈的刺激性鱼臭味,且容易被皮肤以及衣服等所吸附。甲胺可经呼吸道、胃肠道及皮肤吸收,在体内转化成二甲胺或氧化生成甲酸。甲胺对眼、皮肤和呼吸道粘膜有强烈的刺激和腐蚀作用,对机体全身有拟交感神经作用。甲胺常使用于药物、有机氮农药、染料、炸药和表面活性剂等生产过程中,我国工作场所空气中甲胺短时间接触容许浓度均为0.01ppm,时间加权平均容许浓度均为0.005ppm。
现阶段国内外对甲胺的治理方法主要包括物理法和化学方法。相比而言,采用生物法降解恶臭气体具有降解彻底、成本低、无二次污染等优点,因此受到国内外研究者的关注。据报道,由于目前单一菌种对甲胺的降解能力有限,目前已有一部分研究者通过接种混合菌种对甲胺进行降解研究,使用新的单一菌种对甲胺进行降解的研究却鲜有文献报道。因此筛选出高效率、低成本的甲胺降解菌对恶臭有机含氮废气的净化方面具有非常重要的意义。
发明内容
本发明的目的是为了克服现有技术的缺陷,提供一株具有甲胺降解能力的梭状芽孢杆菌。该梭状芽孢杆菌GDUTAN2属于芽孢杆菌属的一个新变种,具有优异的甲胺降解能力,能降解环境中的甲胺,且甲胺降解率高。

实施例1
一株具有甲胺降解能力的梭状芽孢杆菌,该菌株的名称为梭状芽孢杆菌(Lysinibacillus fusiformis)GDUTAN2,保藏在中国典型培养物保藏中心,保藏地址为湖北省武汉市武昌区八一路299号武汉大学校内;保藏编号为CCTCC NO.:M 2017284,保藏日期为2017年5月24日。
本实施例的梭状芽孢杆菌GDUTAN2分离筛选自广东省广州市某垃圾填埋场渗滤液。其分离纯化方法如下:所用的驯化培养基为无机盐培养基g/L(每1000mL无机盐培养基含K2HPO4·3H2O 1.2g,KH2PO41.2g,NH4Cl 0.4g,MgSO4·7H2O 0.2g,FeSO4·7H2O 0.01g,1mL微量元素液(g/L):CaCl2·2H2O 0.2g,MnSO4·4H2O 0.2g,CuSO4·2H2O 0.01g,ZnSO4·7H2O0.2g,CoCl2·6H2O 0.09g,Na2MoO4·2H2O 0.12g,H3BO30.006g)。首先取1mL垃圾渗滤液稀释100倍,接种至营养肉汤中,在摇床温度为37℃、转速150rpm条件下好氧培养1天。取经富集的菌液1mL,接种在含甲胺的无机盐营养液中,在摇床温度为37℃、转速150rpm条件下好氧培养5天后以10%接种量移入下一浓度驯化,底物驯化梯度分别为:10,20,50和100mg/L。将终浓度驯化液做10-1~10-6的稀释,分别取稀释10-5和10-6倍的稀释液200μL涂布到以甲胺为唯一碳源的固体琼脂平板(含甲胺的固体培养基为:每升上述无机盐培养基中加入琼脂18g和甲胺4mg)上,放入35℃恒温箱中培养3天,挑选不同形态单菌落进行甲胺降解率的测定,选择降解率最高的菌种进行纯化。
降解率的测定:在甲胺生物降解的过程中定时取样通过分光光度法测定降解率。降解率=(初始浓度-终浓度)/初始浓度。
分光光度法测定甲胺的浓度:分别取一定量的甲胺降解液于l0mL比色管中,以吸收液(0.01M HCl)稀释至2.0mL,分别加入缓冲液(80mL蒸馏水内溶解4.08g磷酸二氢钾、1.6g硼砂,再加入5.0MNaOH溶液6.35mL,用水稀释至100mL)4.0mL,重氮盐溶液(10mL对硝基苯胺盐酸溶液中加入亚硝酸钠溶液1.0mL,混匀)0.4mL,摇匀,放置40min,再加入5M NaOH溶液1.0mL,混匀,放置20min,于波长510nm处比色定量。
将纯化得到的菌落进行鉴定,鉴定结果如下:
(1)菌体的形态特性:
a.采用常规的细菌生理生化鉴定方法和电子显微镜观察,所筛选的梭状芽孢杆菌的细胞染色为革兰氏阳性;在电子显微镜下观察,其形态为杆状,菌体大小为(1.1~1.4)×(2.3~6.0)μm,周生鞭毛,如图1所示;
b.菌落的形态特性:在LB固体培养基培养24h后,菌落边缘整齐,圆形,白色,透明,菌落直径为1~2mm;
c.主要的生理生化特征如表2所示:
表2 梭状芽孢杆菌的各项生理生化特征
上述结果表明本发明所筛选的细菌与梭状芽孢杆菌属的生理生化特性很相似。
(2)提取细菌基因组DNA,采用细菌的16S rDNA通用引物:
上游引物:F27(5'-AGTTTGATCMTGGCTCAG-3')
下游引物:R1492(5'-GGTTACCTTGTTACGACTT-3')
扩增其16S rDNA全部基因,测序结果如SEQ ID NO:1所示。
将SEQ ID NO:1中所示的长为1398bp的16S rRNA基因序列与Genbank中已登录的基因序列进行比对分析发现菌株与Lysinibacillus fusiformis KNUC423的同源性高达100%。
综合上述的生理生化特性、16S rRNA基因序列结果,本发明所筛选的菌株应归属芽孢杆菌属的一个新变种,命名为梭状芽孢杆菌(Lysinibacillus fusiformis)GDUTAN2。
该梭状芽孢杆菌(Lysinibacillus fusiformis)GDUTAN2于2017年5月24日保藏于中国典型培养物保藏中心(CCTCC),保藏地址为湖北省武汉市武昌区八一路299号武汉大学校内,保藏编号为CCTCC NO.:M 2017284。
