A polysaccharide (Biopolymer B-16) being produced by cultivating Alcaligenes latus strain B-16 (FERM-2015) and having at least one function selected from water absorption, moisture absorption, humectant capability, thickening capability, suspension stability, emulsion stability and dispersant capability along with high biodegradability and which can be used without creating any environmental hazard such as secondary pollution, said Biopolymer B-16 consisting essentially of rhamnose, fucose, glucose, mannose and glucuronic acid which are present in a molar ratio of

Polysaccharide, and water absorbent, moisture absorbent or humectant and

A vessel capable of passing a liquid therethrough is packed with a support having at least hydrophilicity and microorganism cells are inoculated to the support, retained and cultivated therein. A reaction substrate is fed to the vessel and brought into contact with the microorganism, whereby the microorganism is allowed to propagate within the support and act upon the reaction substrate to induce decomposition or synthetic reactions thereof.

Biochemical treatment by microorganic method

Microorganisms of a species selected from the group consisting of the specific species belonging to genus Nocardia, genus Pseudomonas, genus Brevibacterium and genus Corynebacterium, when cultured in a culture medium containing a phthalic acid ester as a carbon source, assimilate the phthalic acid ester and decompose it into carbon dioxide gas and water.
