FTIR analysis of biopolymer degradation using Streptomyces microflavus DG19 in liquid cultures and compost

Abstract

The data and files contained in this dataset are related to the scientific publication "Degradation of biomaterials by Streptomyces microflavus DG19: depolymerization activity, genome mining, and soil burial assessment". This study evaluates the capacity of the bacterium Streptomyces microflavus DG19 to degrade a selection of biopolymers, highlighting its potential as a whole- cell biocatalyst for enhancing composting and developing sustainable remediation strategies for bioplastic waste. This dataset provides the raw Fourier-transform infrared spectroscopy (FTIR) data used to characterize the structural changes on the surface of various biomaterials after being subjected to degradation by S. microflavus DG19. The analyzed materials include poly(3- hydroxybutyrate) (PHB), poly(ε-caprolactone) (PCL), and post-consumer items made of poly(3- hydroxybutyrate-co-3-hydroxyhexanoate) (PHBH) and PHB. The data consists of spectra collected from control samples and samples treated with the bacterium in two different experimental conditions: liquid culture and simulated soil burial (compost). The FTIR analysis confirmed the degradation process by revealing changes in characteristic vibrational bands, particularly the carbonyl (C=O) and ester (C-O-C) stretching regions, which correspond to the hydrolysis of the polymer backbone. Overall, these spectral data provide key molecular-level evidence supporting the paper's findings on the depolymerization activity of S. microflavus DG19.readme.txt (6.928Kb)***Dataset contents*** DG19_compost_FTIR.png (553.7Kb) DG19_liquid_cultures_FTIR.png (543.4Kb) PCL_compost_control.csv (137.0Kb) PCL_compost_DG19.csv (136.9Kb) PCL_film_DG19.csv (136.9Kb) PCL_film_control.csv (136.9Kb) PCL_film_DG19.csv (136.9Kb) PHB_compost_control.csv (136.9Kb) PHB_compost_DG19.csv (136.9Kb) PHB_cup_compost_control.csv (136.9Kb) PHB_cup_compost_DG19.csv (136.9Kb) PHB_film_control.csv (136.9Kb) PHB_film_DG19.csv (136.9Kb) PHBH_card_compost_control.csv (136.9Kb) PHBH_card_compost_DG19.csv (136.9Kb)File readme.txt (6.928KbKb) is under licence public domain CC0Dataset for: Agapov, A., Pantelić, B., Ponjavić, M., Herrera, D.
