Bionolle 3020 md

In the experiments, the commercially available polybutylene succinate (PBS) Bionolle 1020 MD and the polybutylene succinate adipate (PBSA) copolymer Bionolle 3020 MD were purchased from Showa Denko K.K. (Tokyo, Japan). For the tensile test, the samples were formed into dog-bone shaped specimens by the use of an injection molding machine (Allrounder 420C, Arburg, Loßburg, Germany) according to the ISO-527-2-1A standard. The polymer materials were formed at 180 °C (PBS, 1020 MD) and 170 °C (PBSA, 3020 MD).

Polybutylene succinate (PBS) and polybutylene succinate-co-adipate (PBSA) under the trade names Bionolle 1020MD and Bionolle 3020MD, respectively, were purchased from Showa Denko K.K. (Japan). Polycaprolactone (PCL) was obtained from TRESNO (Poland). Chemicals used to prepare the culture media and cartridges for ion-exchange chromatography Bio-Scale Mini UNOsphere Q (strong anion exchanger) 5 mL and 1 mL, Bio-Scale Mini UNOsphere S (strong cation exchanger) 5 mL and 1 mL (GE Healthcare, Sweden) were purchased from Sigma-Aldrich (Germany). 0.5% biopolymer emulsions were prepared as previously described (Urbanek et al. 2021 (link)) and used in plate and turbidimetric assays to determine the biodegradation activity at each step of the purification procedure.
