Abstract
Growth ofP. putida andP. fluorescens on organic silicon compounds was investigated. Both strains could grow on low-molar-mass oligomeric organo-silicon compounds of M2D up to M2D5 type and on polydimethylsiloxanes with a viscosity higher than 1.46 Pa s (20 °C). Linear α, ω-polydimethylsiloxanediols were attacked only by a mixed culture of the two bacteria. Dodecaethoxypen-tasiloxane and tetraethoxysilane were rapidly degraded, yielding ethanol, trimethoxysilane was transformed to trimethylsilanol. Organosilicon compounds can thus be transformed by a specific microflora and in the natural environment degraded by a mechanism similar to that of other organic compounds.
