However, the
pH changes in the medium containing calcium phytate were
very small only from 7.0 (initial value) to 6.30 (the lowest),
and the content of soluble phosphates in supernatant of
culture medium containing calcium phytate were much lower
than those of inorganic phosphate, even the production of available phosphorus could be negligible in inoculated
samples comparing with uninoculated samples (Fig. 1-C).
