[Objective] The aim was to provide the references for development and utilization of fu-brick tea.[Method] The researches on the characters,growth condition,utilization on nutritional ingredients of Eurotium cristatum,which was the dominant fungus in the fungus growing process of fu-brick tea,and the changes of major components occurred in fu-brick tea in this process were summarized.[Result] Most strains of E.cristatum grew faster on CZG and PDA media and the suitable temperature and optimum pH value for their growth were 25-35 ℃ and 5 resp.Organic nitrogen(N) had better promoting effect on growth of colony;inorganic N,amide N and ammonia N were favorable to germination of spores;the research results about influences of carbon source on growth of colony were inconsistent.E.cristatum could enhance N content in fu-brick tea,reduce its contents of theobromine and theocin and increase its contents of phaeophorbide ester a and b,carotenol and β-carotene.[Conclusion] The further research on the aspects of physiological and functional characteristics of E.cristatum and its relationship with formation of fu-brick tea quality was needed.
