In this experiment, Eisenia earthworms as raw materials by, respectively, cut it into pieces - cryogenic - crushing and freezing - the smash after two groups of earthworm powder, phosphate buffer extraction, too earthworm powder extraction after high-speed centrifuged liquid, and E. coli a P. aerugi

This lab is based on pure love earthworm wins as a raw material, cut it into pieces, individually, through low-temperature refrigeration - crushed and shredded-refrigerated after earthworm powder, two groups with phosphate buffer solution, the high-speed centrifuge with earthworm powder after centri

This experimental to pure love wins earthworm for raw materials, respectively by cut broken-low temperature frozen-crush and low temperature frozen-crush processing Hou get two group earthworm powder, with phosphate buffer liquid dip to, by high speed centrifugal machine centrifugal Hou was earthwor
