In this study, the effects of Lavandula angustifolia, Tilia cordata and Rosa canina on cellulose production by Komagataeibacter intermedius strain were investigated. T. cordata was found as the most effective plant (10.64 g/L BC), under the following optimized conditions: 50 g/L plant amount, 8% lactose, 15% inoculum amount at pH=6.0. Total phenolic contents of L. angustifolia (55.42 mg/g), R. canina (16.54 mg/g) and T. cordata (60.03 mg/g), and total protein amounts of L. angustifolia (7.89 g/L), R. canina (3.54 g/L) and T. cordata (5.13 g/L) were analyzed. It has been established that phenolic and protein substances contribute significantly to cellulose formation. Physicochemical analysis showed that all the peaks obtained from FTIR analysis are distinguishable for BC and pellicles show high thermal stability. This research is the first report on the usage of L. angustifolia, R. canina and T. cordata plants as low-cost substrates in BC production with high yields.
