Cultivation of several Bacillus strains with
different concentrations of liquid manure. The strains were cultivated
at 35°C for 96 h in 500-ml conical flasks equipped with three
baffles containing a total volume of 100 ml of medium. Medium E was
replaced stepwise by increasing the fraction of liquid manure, as
follows: 0% (vol/vol) (□), 33% (vol/vol) (▨), 50% (vol/vol)
(▧), 66% (vol/vol) (▩), and 100% (vol/vol)
().
