Vegetative cells are Gram-negative, but sporangia and presporal forms are
Gram-positive; nonmotile, 0.5-0.7 x 1.8-7.0 µm. Spores: ellipsoidal, central to
terminal, thick-rimmed swelling the sporangia, seldom free. Parasporal crystals may
be produced.

On agar medium form small (< 1 mm), yellow-brownish to cream colonies. Maximum
temperature, 35 ºC; minimum temperature, 20 ºC. Optimal temperature 28-30 ºC.
Grow in anaerobic agar. No growth in nutrient broth or in 2, 5 or 7% NaCl.
More fastidious nutritionally than P. popilliae.
Can be maintained indefinitely by serial transfer in diphasic J-medium (Haynes and
Rhodes, 1963). No growth at pH 5.7.

Spores withstand at least 85 ºC. Less widespread than P. popilliae
Although sporulation can be evoked by injection of vegetative cells or spores of P. lentimorbus into susceptible grubs, sporulation in
laboratory media has been brought about only by Steinkraus and Tashiro (1955).
Vancomycin sensible. Resistant to 0.001% lysozyme.

Infects the larvae of the Japanese beetle (Popillia japonica Newman) and the European chafer (Amphimallon majalis
Razoumowsky); the larvae become milky white because of the prolific production of spores by the bacilli in the hemolymph .
Pure cultures can be isolated most readily from dry films of hemolymph of infected larvae;
Is a weapon for the control and elimination of the Japanese beetle and the European chafer.

Acid is produced from glucose, galactose, maltose and mannose.
Acid is not produced from mannitol, arabinose, xylose and trehalose.
Negative results for hydrolysis of starch, reduction of nitrate to nitrite, decomposition of casein, Voges-Proskauer test, citrate utilzation,
indole production, gelatin liquefaction, catalase, phenylalanine deamination, degradation of tyrosine, hydrolysis of urea, oxidase and
dihydroxyacetone.
