- Malt extract agar medium was added to Malt extract 20 g (Difco), Bacto agar 15 g (Difco) in 980 ml of distilled water, adjusted to pH 5.0 and autoclaved at 121 °C for 15 minutes.
- a petri dish of 90 mm ⁇ 15 mm was used for the isolation and cultivation of fungi, and a petri dish of 60 mm ⁇ 15 mm was used to separate and culture the fungi.
- various dominant strains should be selected through a morphological approach such as dilution ratio and colony color, size, and shape.
- the fungus is inoculated in the complex medium after separating the end of the mycelia using a scalpel.
- 5 fungal strains are also subcultured by selecting the most viable medium from the inoculated medium.
- REP-PCR is a molecular biological method that analyzes the structure of bacterial chromosomes and is a fingerprinting method that can distinguish each bacterial strain from other bacteria. Genetic characterization was performed following each procedure below to perform REP-PCR.

- DNA fragments amplified by each PCR were taken, 1.2-1.5% agarose gel with EtBr was added, and 6x dye was mixed with the sample in a 1: 5 ratio to load as much as possible. Since most PCR products are between 100 and 1000 bp, load a 100 bp ladder together and electrophoretize as slowly as possible (50 V) so that the middle of bromophenol blue and xylene cyanol dye goes to the middle of the entire gel. Strains with the same DNA pattern on the gel are considered to be the same strain.
- the 16S rRNA (ribosomal Ribonucleic acid) gene is used for the genetic classification of bacteria and can be identified at the genus and species levels of bacteria classified through REP-PCR.
- 16S rRNA is an RNA that interacts with various proteins to form a ribosome, based on the genetic similarity of 16S rRNA because its complete sequence or base sequence for oligonucleotide list has been found in more than 2000 bacteria. Bacteria can be divided into several major groups. Since the rate of change of the 16S rRNA gene sequence is much less than that of other gene sequences in most genomes, it is recognized that the degree of similarity of 16S rRNA sequence reflects the phylogenetic distance between organisms.
- the method of identifying the microorganisms according to the similarity by analyzing the nucleotide sequence of the 16S rRNA gene fragment has been used as a representative identification method for identifying microorganisms, in particular, industrially useful microorganisms, together with fatty acid analysis and carbohydrate self-analysis.
