Quantification of efficiency of aminoglycosides in alginate polymerization.

(a) TLC of commercial SA and Wakame extract show oligosaccharide profiles; the black arrow shows the flow direction of the mobile phase. (b) Optical density of commercial SA solution for different aminoglycosides; GS, KS, NS, SS, KDS, and TS. (c) Image of wells in a microtiter plate for commercial SA solution and different aminoglycosides; white turbidity led to higher optical density values. (d) Optical density of Wakame extract after addition of different aminoglycosides. (e) Image of wells in a microtiter plate for Wakame extract solution and different aminoglycosides. (f) Malleability and form fitting alginate biopolymer using KDS. Malleability and form fitting alginate biopolymer using KDS after kneading; twisted strands (left) and fingerprint capture (right). (g) Biopolymer made from Wakame extract using KDS.
