Abstract
Cultures of 10 different bacteria were used to serve as food sources for axenically grown
Acanthamoeba castellanii, Acanthamoeba polyphaga
, and
Hartmannella vermiformis
. The nonpigmented enterobacteriaceae
Escherichia coli
K-12 and
Klebsiella aerogenes
appeared to be excellent feed to all three amoebae. Hardly any growth or ammonium production was observed in tests with
Chromatium vinosum
and
Serratia marcescens
, which share the presence of pigmented compounds. Distinct differences in net ammonium production were detected and were correlated to the amoebal growth yield. In general, growth of amoebae and ammonium production increased in the order
A. polyphaga, A. castellanii
, and
H. vermiformis
.
