OBJECTIVE: To establish a microbial limit test for compound Metallurgical wood chips. Methods: According to the Chinese Pharmacopoeia 2005 edition of the three methods of microbiological limit of inspection microbial compound wood veneer microbial limit test to verify and determine the appropriate test methods. Results: The plate recovery <70%, medium dilution and membrane filtration recovery> 80%, Escherichia coli test can be used to detect bacteria by routine method, coliform bacteria test can be detected using the medium dilution method Test bacteria. Conclusion: This product bacteria, mold and yeast examination can be used medium dilution method, the detection of Escherichia coli can be used conventional method, coliform bacteria examination can be used medium dilution method.
