Affinity chromatography A form of chromatography in which separation is achieved by utilizing highly specific biochemical interactions, such as steric-or charge-related conditions, between me analyte and a molecule immobilized on a column. It is different from most forms of chromatography in mat analytes do not continuously elute from me column - only mose mat interact wim me stationary phase are retained and mus separated from omer components of me mixture under investigation. These immobilized materials are eluted from me column after all omer materials have been removed.

The term "Allelopathy" was coined by Molisch (2 ) to refer to both detrimental and beneficial biochemical interactions anong all classes of plants, including microorganisms. Because the root word "pathy," however, implies detrimental interactions, Rice (3) defines "allelopathy" as follows "Any direct or indirect harmful effects of one plant (including microorganisns) on another through the production of chemical compounds that escape into the envirorment." Perhaps, the term "allelopathy" should be extended to include the manifold mutual effects of metabolic products of both plants and animals. Now Rice includes beneficial interactions (18).

Other roles for noxious metabolites produced by certain phytoplankton species include mediation of allelopathic interactions [47]. Allelopathy covers biochemical interactions among different primary producers or between primary producers and microorganisms. These can provide an advantage for the producer in the competition among different photoautotrophs for resources. Although not directly involved in chemical defense, allelopathic metabolites can affect the dominance and succession of species in phytoplankton therefore they are crucial for understanding plankton composition. In contrast to the fresh water environment, the location of many studies on the role of allelopathic interactions, which have identified active compounds [47], only few studies have addressed this topic in the marine environment. 

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).

The in vitro and in vivo test methods available to study combined actions and toxicological and biochemical interactions of chemicals in mixtures are essentially the same as those used for the study of single chemicals in order to examine their potential general toxicity and special effects such as mutagenicity, carcinogenicity, and reproductive toxicity. 

Like many other typical bacterial secondary metabolites, AGAs tend to be produced as complex product mixtures released from their producing cells. We interpret this as a strong sign for ongoing evolution of the respective pathways and ligand-target site interactions. In other words the biochemical interactions... 

In spite of the early suggestions concerning apparent allelopathic effects, no solid scientific evidence was obtained to support the suggestions until the present century. The term allelopathy was coined by Molisch in 1937 to refer to biochemical interactions between all types of plants, including microorganisms traditionally placed in the plant kingdom (3). His discussion indicated that he meant the term to cover both inhibitory and stimulatory biochemical interactions.
