Barium is also found in anaerobic sewage sludge at concentrations ranging from 100 to 9,000 ppm (mean concentration 800 ppm) and in aerobic sewage sludge at concentrations ranging from 100 to 300 ppm (mean concentration 200 ppm) (Sommers 1977).

Doi et alP reported on the biodegradation of PHAs. The mechanism of biodegradation of these polymers has been studied and involves the enzyme, bacterial esterases, which depolymerizes the polymer to monomers, dimers, and trimers. Budwill et al reported the rapid mineralization of PHB and PHBV in anaerobic sewage sludge, and more than 90% metabolized to methane and...
