title: [Comparative Analysis of Different Inonotus obliquus].
abstract: OBJECTIVE
  To screen optimal Inonotus obliquus strains that is suitable to cultivation, extracting effective components on industrialized production, genetics and breeding.
  
  
  METHODS
  Inonotus obliquus mycelia from different countries were used. High quality strain was screened by comparing the antagonism between Inonotus obliquus and penicillium. The contents of crude fat, crude ash, crude protein and crude fiber were analyzed.
  
  
  RESULTS
  It was showed that antagonism ability of Finnish birch was the strongest, its mycelia diameter was up to 53. 27 mm. It was also showed that nutritional ingredient was abundant in artificial cultured Inonotus obliquus strains. The contents of crude fat and crude protein in Finnish birch were higher, which was 1. 93% and 20. 23%, respectively. The contents of crude fat and crude protein in NBRC8681 strains were lower, which was 1. 55% and 19. 85%, respectively. The content of crude ash of JL04 strains was higher(8. 76%). The content of crude ash of NBRC8681 strains was lower(6. 8%). Crude fiber content was higher in HLJ01 strains, its content reached to 45. 09%. The least content appeared in MAFF420101 strains, whose crude fiber content was only 38. 27%.
  
  
  CONCLUSIONS
  The strains of Finnish birch, HLJ01 and JL04 are suitable to exploitation.
