Title:
【発明の名称】ヒドロキシ酸を放出する化合物およびその使用方法
Document Type and Number:
Japanese Patent JP3239899
Kind Code:
B2
Abstract:
The preferred embodiments provide for a family of novel compositions to serve as substrates that release hydroxy acid slowly over time. Preferably the hydroxy acid is an alpha-hydroxy acid, more preferably it is lactic acid. The compositions are preferably made by reaction of poly(lactic acid) with multifunctional alcohols. Also disclosed are formulations based on the compounds and methods of use for both the compositions and the formulations. The preferred use of the compositions and formulations is for bioremediation purposes wherein they provide a time-release source of lactic acid to support the growth and reductive activity of microbes present in a system or medium, such as an aquifer, bioreactor, soil, industrial process, wastestream, body of water, river or well. The microbes destroy or inactivate compounds which are capable of being reduced, such as nitrogen-containing organic compounds, oxygen-containing organic compounds, polyaromatic hydrocarbons, and halogen-containing organic compounds.
