Biofunctionalized Nanofibers Using Arthrospira (Spirulina) Biomass and Biopolymer

Table 1

Source of polyhydroxybutyrate (PHB) and polyhydroxybutyrate-co-valerate (PHB-HV) and the composition of the solutions used to manufacture nanofibers constructed from PHB or PHB containing 5% or 12% (w/w) commercially available PHB-HV and biofunctionalized using Arthrospira biomass. Nanofiber diameters are given as the mean ± standard deviation.
