Fabrication and Biodegradability of Starch Cell-Plastics as Recyclable Resources

Applied Sciences, 2021
Recently, cell-plastics, which are composed of unicellular green algal cells and biodegradable compounds as ingredients and fillers, have been suggested as carbon-recyclable materials instead of petroleum-based plastics.

Estimating the Biodegradability of Treated Sewage Samples Using Synchronous Fluorescence Spectra

Sensors, 2011
Synchronous fluorescence spectra (SFS) and the first derivative spectra of the influent versus the effluent wastewater samples were compared and the use of fluorescence indices is suggested as a means to estimate the biodegradability of the effluent ...

Biodegradable Polydepsipeptides [PDF]

International Journal of Molecular Sciences, 2009
This paper reviews the synthesis, characterization, biodegradation and usage of bioresorbable polymers based on polydepsipeptides. The ring-opening polymerization of morpholine-2,5-dione derivatives using organic Sn and enzyme lipase is discussed. The dependence of the macroscopic properties of the block copolymers on their structure is also presented.
