NOVELTY - A metal complex polymer, comprises: alcohol radical or its reversible compound; polymer consisting hydroxyl radical, hydroxyl radical with amino radical, saccharide, sugar-metal, polysaccharide-metal polymer or their reversible compounds, usnic acid in compliance with saccharide, or metal chelating agent in compliance with saccharide; metal salt, metal ion, ore, or bone; and amino compound, or amine compound including a protein revered with each other for several times.    USE - For preparing a metal complex polymer or its solution, useful for oxidation-condensation, condensation reaction, biochemical reaction for fermentation, metal enzyme biological catalyst, culture medium or storage system, food and medicare, chemical material production in plants, oil product processing, nano scale filter, nano scale material for fermentation, liquid crystal or semiconductor manufacture, nano scale plastic or fiber, nano organic material and nano ceramic material (claimed), including production or medicines, feeds, antibiotics, disinfectants, grass killer, dyes, purified algae, cultivated fatty acids and esterified diesel; by modifying an oil product into a diesel; for processing organic wastes into fertilizers and feeds; and fermenting food and producing organic gases (including a methane gas) and their derived technological applications.    ADVANTAGE - The metal complex polymer comprises metal esterification or biological enzyme for converting oils and carboxyl compounds into fatty acid esters, provides improved esterification catalyst; is capable of reacting with highly stable oil or carboxyl compound; and provides a simple way to achieve the same esterification, unlike a conventional process that requires high temperature and high pressure for the reaction and incurs high cost and investment; as compared to the prior art catalysts. The symbiosis of fungus and marine algae produces a lichenized and/or algacultured that absorbs carbon dioxide and water in the air for the reaction; absorbs nitrogen to produce saccharide, proteins, usnic acids and fatty acids in a condensation reaction, and further carries out esterification and fermentation reactions or other esterifications, which results in formation of artificial diesel solution. The oil product composed of the metal complex polymer solution and made by a special fermentation reaction improves and modifies the quality of matters, and develops a diesel solution with high efficiency, high density and high quality; and increases the modified oil products and modifies an oil product into diesel, while increasing the heat of combustion of a bio-diesel, as compared to the achieved with prior art methods.    DETAILED DESCRIPTION - A metal complex polymer, comprises: a R-COOH radical or its reversible compound; a polymer consisting a hydroxyl radical, an hydroxyl radical with an amino radical, a saccharide, a sugar-metal, a polysaccharide-metal polymer or their reversible compounds, an usnic acid in compliance with a saccharide, or a metal chelating agent in compliance with a saccharide; a metal salt, a metal ion, an ore, or a bone; and an amino compound, or an amine compound including a protein revered with each other for several times. The R-COOH radical is an organic acid or an organic acid substance including at last one metal complex polymer.
