Phosphate solubilizing bacteria (PSB) who prefer pH range 6-7.5 and grows well in this pH range. But, most of the PSB secrets organic acid as their functional biomolecules for releasing insoluble P from the fixation.

As a result, the solution become acidic and the bacterial colony reduces, accordingly. This is happening both in culture media as well as in the field soil.

How to manage these PSB in such situation? Lower pH with organic acid is beneficial for mineralization of insoluble Phosphorus but detrimentral for growth of bacteria. What will be the remedies in such case??

Ref. article is expected in that cases.
