Interactions between algae bacteria

Deciphering a beneficial chemical interaction between algae and bacteria... 

Allelopathy is defined as biochemical interactions between one plant or microorganism (alga, bacteria, or virus) and another plant through the production of chemical compounds - secondary metabolites (allelochemicals), which influence, direct or indirect, harmful or beneficial, plant growth and development (Rice 1984). Allelochemicals are present in almost all plants and in many tissues, like leaves, stems, flowers, fruits, seeds, roots, or pollen and may be released from plants into the environment by volatilization, leaching, root exudation, and decomposition of plant residues (Chou 1990).

FIGURE i Diagrammatic representation of the structure and function of bacterial biofilms. Dissolved organic matter (DOM) is sorbed onto the biofilm (1), additional DOM is released from algae and organic particles (2). The organic matter is cleaved by extracellular enzymes (3). Interactions can occur between clones of syntrophic or competing bacteria (4). See Section II for details.
