Micro-organisms of M.\n.r, Sai? 

 The results are tabulated as follows: 



TABLE G4. MODIFIED I S< KINSKY SOLI TION 





1 Trace 14 days. 



The development of Ps. fluorescens, Ps. mesenterica. 

 XXXVI, and LI was more rapid but less persistent on the di- 

 luted media than on the full concentrations. All strains except 

 Ps. longa, Ps. putrida, and CXV developed well with surface 

 membrane and fluorescence. Ps. longa grew well but without 

 fluorescence; no growth occurred with Ps. putrida or CXV. 

 Transfers from tubes of these latter strain- to nutrient broth 

 developed typically, showing that the lack of growth on the 

 Uschinsky solutions was not due to a failure to inoculate.
