Thiourea effect on the lignin biodegradation
(1987)
Lignin degradation by peroxidase or an extracellular crude ligninase in the presence of thiourea is enhanced. Veratryl alcohol, exhibits the same behaviour in both cases. Thiourea is proposed as an additive in biopulping
Biodegradation kinetics of oil palm empty fruit bunches by white rot fungi
The biodegradation of lignin, cellulose and hemicellulose from oil palm empty fruit bunches by white rot
fungi Phanerochaete chrysosporium and Pleurotus ostreatus was investigated. The results showed higher
mass loss and ...
Biodegradability of PP/PHBV (70/30) blend films
(2013-12-01)
This study aimed to investigate the biodegradation of polypropylene/ poly(hydroxybutyrate-co-hydroxyvalerate) (PP/PHBV) blend (70/30, w/w) films in soil, monitoring the evolution of CO2 using the respirometric method. The ...
