Abstract
In a previous paper, black yeast was found to produce poly(L-malic aci d) in large yield by fermentation with glucose as the carbon source. B ased upon characteristic NMR spectra, the primary structure of this po lymer was elucidated as poly(beta-LO-malic acid) having branched chain s. Thermal analysis by DSC shows neither T(s) nor T(m) below its decom position temperature T(d) on the solid state polymer.
