Degradation of pretreated agroforestry residues by selected micromycetes [PDF]
Zbornik Matice Srpske za Prirodne Nauke, 2022 Nowadays, there are huge amounts of lignocellulosic materials left in agroforestry practice, which can be transformed into useful products. Biomass exploitation could be aiming not only at replacing conventional energy sources but also at ...

Enzymatic depolymerization of emulsan [PDF]
Journal of Bacteriology, 1983 Emulsan, the polyanionic emulsifying agent synthesized by Acinetobacter calcoaceticus RAG-1, was depolymerized by an enzyme obtained from a soil bacterium YUV-1. The extracellular emulsan depolymerase was produced when strains RAG-1 and YUV-1 were grown together on agar medium.
