Abstract

Fermentation of chayote fruit and bamboo shoots extracts using Acetobacter xylinum have been done to produce nata de chayote (NDCh) and nata de bamboo (NDB). The NDCh and NDB were pressed to obtain thin membranes. Then tensile strength, strain, water absorption capacity (WAC), and functional group of the membrane were characterized. Mass of chayote fruit and bamboo shoots used as substrates for NDCh and NDB have been varied to look for optimum condition to obtain maximum mechanical properties. The maximum mechanical properties obtained from NDCh membrane were 74.64 MPa for tensile strength, 6.05% for strain and 836.23% for WAC. Whilst the maximum mechanical properties obtained from NDB membrane were 57.28 MPa for tensile strength, 8.37% for strain and 591.86% for WAC. They show that the different substrate produce different membrane properties. The FTIR spectrums of NDCh and NDB membranes show that they had no significant differences. These different properties of membranes can be used for different applications.
