Interactions between sediment bacteria and available phosphate
necessary for algal production in a eutrophic lake were studied.
Twenty percent of the organisms isolated solubilized phosphate forms
such as CaHPO₄, Ca₃(PO₄)₂, FePO₄, Mg₃(PO₄)₂ and Al₂(PO₄)₂.
Solubilization of phosphates occurred under conditions of aerobic
growth.
Upon quantitative analysis, some isolates were capable...
