Description

一种暗褐网柄牛肝菌液体菌种的培养方法
技术领域
本发明涉及生物技术领域,特别是(产自云南热带地区)暗褐网柄牛肝菌液体菌种的培养方法。
背景技术
暗褐网柄牛肝菌(Phlebopus portentosus)是一种味道鲜美,营养价值丰富,深受产地消费者喜爱的美味食用菌。目前仍不能人工栽培,市场上销售的暗褐网柄牛肝菌子实体均采自野生自然生长。液体发酵是微生物产品规模扩大生产的基本方法,它不受环境与气候条件的影响、限制,短时间内可获得大量的生物产品,工艺易于放大,重复性、安全性好。
目前由于暗褐网柄牛肝菌子实体不能规模人工栽培,野生牛肝菌资源不能满足人们的需求,菌丝体液体发酵培养是解决这一问题的最好方法。发酵培养的菌丝体即是液体菌种,液体菌种接种于固体培养基是固体菌种扩培的有效途径。
产自于云南的暗褐网柄牛肝菌味道鲜美,营养价值丰富,有较好的食用及药用价值,是一种较好的保建食品。由于受气候季节条件的限制产量有限,需通过大量发酵培养获得菌丝体以满足其在食品行业的需求。固体菌种的培养也需要液体种作为二级接种体。因此,迫切需要提供一种有效的暗褐网柄牛肝菌液体菌种培养方法。
发明内容
本发明的目的是提供一种暗褐网柄牛肝菌液体菌种快速培养方法。
本发明的技术方案为:暗褐网柄牛肝菌液体菌种的培养方法按以下步骤进行:
a、用菌种培养基培养暗褐网柄牛肝菌子实体组织块制备母种,母种培养基的制备由下述原料及方法配制而成:
马钤薯         150~200g
蔗糖           15~20g
酒石酸铵       1~2g
MgSO4          1~2g
KH2PO4         1~2g
琼脂          15~20g
水            1000ml
pH            6.0
方法:
a1)将新鲜马钤薯洗净,去皮,称量,然后切成薄片,放入大烧杯中,加入定量的水,煮沸20分钟过滤取滤液,加入蔗糖、琼脂、酒石酸铵、MgSO4、KH2PO4,煮沸至琼脂完全溶化,pH值6.0,得母种培养基;将培养基分装于三角瓶中,120℃灭菌30分钟,待冷却后在超净工作台中倒入培养皿中即可使用;
a2)在超净工作台中无菌操作,用解剖刀分离子实体组织块,置于有母种培养基的培养皿中培养菌丝体生长并扩繁;
a3)采集野生的暗褐网柄牛肝菌子实体,去掉子实体表面的泥沙,先用清水冲洗净,凉干然用75%酒精溶液消毒子实体表面,在超净工作台中,将子实体一掰为二,用解剖刀取菌柄与菌盖交界的中间部位2-3mm的菌肉组织块放于倒有菌种培养基的培养皿中,置于28℃的培养箱中培养,培养30天,菌丝体长满培养皿,得母种。
b、用液体培养基发酵培养液体菌种,液体培养基的原料组成如下:
马钤薯          150~200g
蔗糖            15~20g
酒石酸铵        1~2g
MgSO4           1~2g
KH2PO4          1~2g
水              1000ml
pH              6.0
制备方法:
b1)将新鲜马钤薯洗净,去皮,称量,然后切成薄片,放入大烧杯中,加入定量的水,煮沸20分钟过滤取滤液,在滤液加入蔗糖、酒石酸铵、MgSO4、KH2PO4,混匀,pH值6.0,得液体培养基;将配制好的液体培养基分装于三角瓶中,每瓶300ml,120℃灭菌30分钟,待冷却后备用;
b2)将在上述步骤a3中获得的母种转管活化后,将菌丝体连同培养基切成2mm~4mm的碎菌块接种于步骤b1中瓶装的培养基中,在28℃,125r/min回旋式摇床中振荡培养,培养8天得到液体菌种。
本发明提供的暗褐网柄牛肝菌液体菌种培养方法,与已报道的牛肝菌的液体培养配方相比较有如下优点:①培养基营养成份简单,培养基配方中只用了简单的碳氮源(马钤薯、蔗糖、酒石酸铵)及一般的无机盐(MgSO4、KH2PO4),即可进行母种及液体菌种的培养;②培养方法简便,培养皿和摇床即可进行母种及液体菌种的培养;③菌丝、菌球生长速度快。28℃温度条件下,培养30天母种即可长满10cm的培养皿。培养8天液体种的菌丝球均匀分布悬浮于三角瓶的液体培养基中,且生长均匀,大小一致,色泽金黄。用该液体菌种接种固体培养基培养固体菌种,接种3天后菌丝开始萌发生长吃料。
