Abstract

Symbiotic Culture of Bacteria and Yeast (SCOBY) is a by-product in the form of cellulose polymers produced by bacteria in the kombucha fermentation process. Until now, SCOBY products still have application limitations. Several world designers have succeeded in making works using fabrics based on SCOBY. The resulting fabric has a flexible texture and is brown like synthetic leather. Fabrics based on SCOBY are also considered cheap and more environmentally friendly with short production time. The use of SCOBY as a fabric base material still has problems, where the fabric produced from SCOBY kombucha, directly through the drying process, has the characteristic of being very easy to absorb water. Another problem is that SCOBY production in the kombucha fermentation process is difficult to achieve a uniform thickness and SCOBY production in a large surface area is also difficult to stabilize. The development of SCOBY into cellulose fibers can be done by first changing the structure of SCOBY into nanocellulose. This nanocellulose production can then be developed into nanocellulose fibers in the form of threads and then spun to become a complete fabric. The production of nanocellulose is carried out using cellulase enzymes. It is known that cellulase enzymes can be obtained through the growth of bacteria or specific fungi. One of the groups of fungi and bacteria commonly used to produce cellulase enzymes are Trichoderma and Bacillus.

Highlights

  • Cellulose fibers are known to be used as raw material for making fabrics in the textile industry

  • The use of Symbiotic Culture of Bacteria and Yeast (SCOBY) as a fabric base still has problems, where the fabric produced from SCOBY kombucha, directly through the drying process, has the characteristic of being very easy to absorb water

  • This characteristic is a drawback for SCOBY based fabrics, because the water bound in SCOBY based fabrics is difficult to dry and can make SCOBY return to its original shape

Summary

Introduction

Wood cellulose is found in the form of cellulose bundles that stick together due to bonds by lignin. This characteristic is a drawback for SCOBY based fabrics, because the water bound in SCOBY based fabrics is difficult to dry and can make SCOBY return to its original shape Another problem with the use of SCOBY directly as a fabric base material, is that the production of SCOBY in the kombucha fermentation process is difficult to achieve uniform thickness and SCOBY production in a large surface area is difficult to stabilize [4]. This nanocellulose production can be developed into nanocellulose fibers in the form of threads and spun to become a complete fabric.
