Physicochemical properties and characterization of nata de coco from local food industries as a source of cellulose (Sifat fizikokimia dan pencirian nata de coco daripada industri makanan tempatan sebagai sumber selulosa)

Nata de coco, a dessert originally from the Philippines is produced by fermentation of coconut water with a culture of Acetobacter xylinum, a gram negative bacterium. Acetobacter xylinum metabolizes glucose in coconut juice and converts it into bacterial cellulose that has unique properties includin...
