The heavy rains last spring most likely caused Lake Okeechobee to discharge water containing blue-green algae into rivers and canals. The bright green sludge oozed onto docks, dams and rivers and through tributaries into the ocean.
Blue-green algae (cyanobacteria) are a group of prokaryotic, autotrophic microorganisms that contain the photosynthetic pigments (chlorophyll and phycocyanin), Therefore, the DNA shows bacteria

The answer is; donation of a proton to water
Acids are proton donors. As viewed in the equation, the lactic acid partially dissociates in the water to form a conjugate base and hydronium ions. This is a property of an acid. The water acts as a base is donated a hydrogen ion be the lactic acid to form a conjugate acid H3O+.
