1) As bactérias são lisadas pelos fosfatos, cuja atividade lítica varia com o sal de fosfato, os trivalentes sendo mais ativos. 2) A fosfatólise independente da viabilidade da bactéria. 3) A fosfatólise póde interferir nas suspensões com tampões de fosfatos e na preservação de hemoculturas.<br>Bacteria are lysed by phosphates in low concentrations. Differences were observed in the lytic activity according to the salt, the trivalente salt being the more active. The lytic action is not always dependent of the living or dead state of the microorganisms. It seems that this "bacterial phosphatolysis" is of importance for the preservation of microorganisms in culture media or in a simple solution containing phosphates.
