    摘要: A process for preparing a cephalosporanic acid derivative or a 7-acylaminocephalosporanic acid derivative which comprises subjecting an esterifying agent to reaction in liquid sulfur dioxide in the presence of a base with an N-protected-cephalosporin C to obtain a diester, subjecting the diester to reaction in an inert solvent with an iminohalide forming agent to produce an iminohalide, subjecting the iminohalide with a lower alcohol to produce an iminoether, subjecting the product produced, after subjecting the iminoether to reaction with a reactive derivative of an organic acid, to hydrolysis and further eliminating the ester group of the carboxylic acid.

    摘要: The present invention provides a method of detecting microorganisms, comprising the step of converting physical forms of microorganisms by antigen-antibody reaction and successively measuring the information that shows the physical forms of the converted data, and the step of comparing a statistical pattern of the values thus measured and a reference statistical pattern of a control subjected to no antigen-antibody reaction, thus detecting the microorganisms of interest. A change in both patterns, i.e., no correspondence thereof, enables recognition of the presence of the microorganisms of interest.
