Gluconacetobacter sp. gel-SEA623-2, bacterial cellulose producing bacterium isolated from citrus fruit juice

Abstract EN

Cellulose producing bacterial strain was isolated from citrus fruit juice fungus.

The isolated strain was identified as Gluconacetobacter sp.

gel_SEA623-2 based on several morphological characteristics, biochemical tests, and 16S rRNA conducted.

Culture conditions for bacterial cellulose production by SEA623-2 were screened in static trays.

Conditions were extensively optimized by varying the kind of fruit juice, pH, sugar concentration, and temperature for maximum cellulose production.

SEA623-2 has a high productive capacity in citrus processing medium, but not in other fruits.

The optimal combination of the media constituents for bacterial cellulose production is as follows: 10% citrus juice, 10% sucrose, 1% acetic acid, and 1% ethanol at 30 C, pH 3.5.

Bacterial cellulose produced by SEA623-2 has soft physical properties, high tensile strength, and high water retention value.

The cellulose produced by the selected bacteria is suitable as a cosmetic and medical material.
