Agar Characteristics. Feb 1, 1992 · A medium consisting of MYPGP agar supplemented with vancomycin was found to be highly selective for Bacillus popilliae, especially for strains originally isolated from Japanese beetle larvae. Larvae feeding in the soil consume spores of these bacteria and following spore germination in the larval gut, vegetative cells penetrate into the haemocoel. Initially, variable cell yields during steady-state chemostat growth led to a re-examination of growth rates in batch cultures. These specimens were examined using phase contrast microscopy for the presence of the milky disease bacteria, Bacillus popilliae Dutky.
