“…The accessory diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) for analysis of the powdered sample was used to determine spectra in the absorbance mode at room temperature (mid-infrared region, 4000-600 cm −1 ), and the OMNIC software was used to obtain the results. In total, 100 scans were measured with a resolution of 4 cm −1 [ 12 ].…”

“…The chitosan particles were coated with a thin layer of Au-Pd using a sputter coater (Quorum model QI5OR-ES, Sussex, UK) before scanning. Morphological analysis of the chitosan powder was performed particles to investigate the size, shape, and form of the particles [ 12 ]. In addition, the samples were analyzed to determine the elemental composition using an Oxford X-Max 20 energy dispersive X-ray spectroscopy (EDS) detector and an Oxford wavelength-dispersive X-ray spectroscopy (WDS) detector.…”

“…PLA resin is a biodegradable polymer material prepared by polycondensation reaction using lactic acid as the main raw material, which can be extracted from natural renewable resources such as corn and wheat [1][2][3]. The production process has no pollution and the production energy consumption is only equivalent to 20% to 50% of the traditional petrochemical products, while the carbon dioxide gas produced is only 50%, which can get rid of the dependence on oil resources.…”

The polylactic acid (PLA) resin Ingeo 4032D was selected as the research object, with a focus on PLA modification by using polymers such as linear low-density polyethylene (LLDPE), high-density polyethylene (HDPE) and ethylene–propylene-diene monomer grafted with glycidyl methacrylate (EPDM-g-GMA), by using fillers such as nano calcium carbonate and zeolite. In order to characterize the deposition effect of Al2O3 on the film surface by plasma-assisted atomic layer deposition, Bio-oriented PLA (BOPLA) with more uniform thickness than blown film was purchased for study. The mechanical properties, friction coefficient, surface contact angle and water vapour transmission rate of the modified PLA film were compared and discussed. The aim was to find out the most influencing factors of film’s water vapour resistance.

“…Regarding the group of biobased "synthetic polymers", we found poly(lactic acid) (PLA), poly(butylenes succinate) (PBS), bio-polyolefins (bio-PP, bio-PE), and bio-poly(ethylene terephtalic acid) (bio-PET). In this group, PLA and PBS are biodegradable/compostable polymers, and PLA is the most promising biodegradable polymer for different applications, such as food packaging [8,9], automotive applications [10], and biomedical applications [11,12], among others. Bio-PP, bio-PE, and bio-PET are not biodegradable materials, and the only contribution for reducing environmental impact comes from reducing the carbon footprint.…”

Biobased Materials from Microbial Biomass and Its Derivatives

et al. 2020

There is a strong public concern about plastic waste, which promotes the development of new biobased materials. The benefit of using microbial biomass for new developments is that it is a completely renewable source of polymers, which is not limited to climate conditions or may cause deforestation, as biopolymers come from vegetal biomass. The present review is focused on the use of microbial biomass and its derivatives as sources of biopolymers to form new materials. Yeast and fungal biomass are low-cost and abundant sources of biopolymers with high promising properties for the development of biodegradable materials, while milk and water kefir grains, composed by kefiran and dextran, respectively, produce films with very good optical and mechanical properties. The reasons for considering microbial cellulose as an attractive biobased material are the conformational structure and enhanced properties compared to plant cellulose. Kombucha tea, a probiotic fermented sparkling beverage, produces a floating membrane that has been identified as bacterial cellulose as a side stream during this fermentation. The results shown in this review demonstrated the good performance of microbial biomass to form new materials, with enhanced functional properties for different applications.
