CIRCULATION TYPE NOURISHMENT LIQUID CULTURE APPARATUS AND CIRCULATION TYPE NOURISHMENT LIQUID CULTURE METHOD

摘要

PROBLEM TO BE SOLVED: To establish a circulation type nourishment liquid culture method by which the culture can easily be maintained at a low cost in high sterilization effect, and to provide a sterilization apparatus used for the method.;SOLUTION: This circulation type nourishment liquid culture method is characterized by contacting a nourishment liquid with a granular sterilizer capable of eluting at least one metal ion selected from silver and copper, such as silver zeolite or a compound represented by the general formula [1]: M1_aA_bM2_c(PO₄)_d-nH₂O [1] [M1 is at least one k-valent (k is a positive integer) metal ion selected from silver and copper; A is at least one m-valent (m is a positive integer) ion selected from an alkali metal ion, an alkaline earth metal ion, ammonium ion and hydrogen ion; M2 is a tetra-valent metal ion; (n) is the number satisfying 0≤(n)≤6; (a) and (b) are each the positive number satisfying ka+mb=1 or ka+mb=2; (c) and (d) are 2 and 3, respectively, when ka+mb=1, or 1 and 2, respectively, when ka+mb=2].;COPYRIGHT: (C)2004,JPO
