Embodiment 1

[0044] Example 1: Cultivation of "Bailing" production fungus Cordyceps sinensis

[0045] Source of the strain: Firstly, the natural Cordyceps sinensis was collected from Qinghai, and brought back to Hangzhou for isolation and screening, and the L0106 strain was obtained, and the strain was identified as Hirsutella sinensis, which was preserved in a typical culture in China The collection center, the deposit number is CCTCC No: M2011278, which has been disclosed in the previously applied patent CN102373190A.

[0046] This bacterial classification is inoculated on the slant, and the culture medium formula (this is the liquid formula before solidification, makes the slant after being prepared according to the following ratio) is: glucose 2.0% (w / v, 1% means that 100mL culture medium contains 1g, the same below), corn flour 1.0%, potato juice 0.5%, dextrin 0.5%, yeast powder 0.5%, bran 1.0%, silkworm chrysalis powder 2.0%, peptone 1.0%, magnesium sulfate 0.05%, potassium dihydroge...

Embodiment 2

[0047] Example 2: Extraction of total RNA of "Bailing" production fungus Cordyceps sinensis

[0048] Extract total RNA with TRIzol reagent, the steps are as follows:

[0049] 1) Grinding with liquid nitrogen: Put 1 g of fresh bacteria into a mortar, add liquid nitrogen repeatedly to grind until powdery, dispense into pre-cooled 1.5 mL centrifuge tubes, add 1 mL of TRIzol reagent, mix well, and stand on ice. Set aside for 5 minutes to completely separate the nucleic acid-protein complex.

[0050] 2) RNA isolation: Add 0.2 mL of chloroform, shake vigorously for 15 s, let stand on ice for 2-3 min, centrifuge at 4°C, 12000 rpm for 15 min, separate the layers, and take the upper aqueous phase, about 600 μL.

[0051] 3) RNA precipitation: add 500 μL of isopropanol, let stand on ice for 10 minutes, centrifuge at 12000 rpm at 4°C for 10 minutes, and discard the supernatant.

[0052] 4) RNA washing: add 1 mL of 75% (v / v) ethanol, suspend the precipitate, let stand on ice for 10 min, ...

Embodiment 3

[0054] Example 3: Sequencing of the RNA sample of "Bailing" production fungus Cordyceps sinensis

[0055] After extracting the total RNA from the sample, the mRNA was enriched with Oligo(dT) magnetic beads. Add fragmentation buffer to break mRNA into short fragments (200-700bp), use mRNA as a template, use six-base random primers (random hexamers) to synthesize the first cDNA strand, then synthesize the second cDNA strand, and then pass through the QiaQuick PCR kit After purification and elution with EB buffer, end repair, polyA was added and sequencing adapters were connected, then agarose gel electrophoresis was used for fragment size selection, and finally PCR amplification was performed, and the built sequencing library was sequenced with Illumina GA IIx. The original image data obtained by sequencing is converted into sequence data through base calling, that is, raw data or raw reads. The reads containing only the adapter sequence in the original sequencing reads were re...

Abstract

The invention relates to a phospholipase C in a corresponding free fatty acid, which is prepared by hydrolyzing phospholipids via hirsutella sinensis of Cordyceps sinensis (Berk.) Sacc. from 'Corbrin' producing strains, and a gene for coding the phospholipase C as well as an application of the phospholipase C. The homology between an amino acid sequence of the phospholipase C and a protein shown as SEQ ID No.1 reaches above 90%, and the homology between a nucleotide sequence of the coded gene of the phospholipase C and a sequence shown as SEQ ID No.2 reaches above 90%. The cloned DNA with the nucleotide sequence, which is provided by the invention, can be transformed into engineering bacteria via methods of transduction, transformation and combined transferring, so that high expressivity of a host laccase is realized by regulating the expression of the corresponding coded gene of the enzyme which is contained in the corresponding free fatty acid and prepared by the catalytic hydrolysis of the phospholipids, thereby providing an effective way for enlarging biological applications of the phospholipase C. Thus, the phospholipase C has a great application prospect.

Description

[0001] (1) Technical field [0002] The invention relates to a phospholipase C (Laccase) from the "Bailing" production fungus Cordyceps sinensis which participates in the hydrolysis of phospholipids to prepare corresponding free fatty acids, the gene encoding the enzyme and its application. [0003] (2) Background technology [0004] Cordyceps sinensis (Cordyceps sinensis (Berk.) Sacc.) is a complex of Cordyceps sinensis parasitizing on the larvae of Lepidoptera (Lepidoptera) bat moth (Hepialus armoricanus Oberthur) larvae and larval corpses (including subunits and worm bodies ). Cordyceps sinensis is a kind of precious traditional fungal medicinal resources, which has the characteristics of diverse metabolites and biological activities, and has shown great application and development prospects in the field of biomedicine. Cordyceps sinensis has attracted much attention for its extensive and obvious medicinal effects, and is highly respected all over the world. Chinese medici...
