Microbiological characteristics of low salt Mul-kimchi was examined. Mul-kimchi was prepared by mixing of radish (25%), green onion (2.4%), red pepper (1.9%), garlic (1.9%) and salt (0, 0.2, 0.5, 1.0, 1.5, 2.0, 2.5, 2.5, 3.0%) in water and fermented at 4, 15 and $25^{\circ}C$ for 10 days,...

Microbiological characteristics of low salt Mul-kimchi was examined. Mul-kimchi was prepared by mixing of radish (25%), green onion (2.4%), red pepper (1.9%), garlic (1.9%) and salt (0, 0.2, 0.5, 1.0, 1.5, 2.0, 2.5, 2.5, 3.0%) in water and fermented at 4, 15 and $25^{\circ}C$ for 10 days, respectively. During fermentation period, total cell, Leuconostoc sp., Lactobacillus sp., Streptococcus sp., Pediococcus sp., coliform bacteria, gram (-) bacteria and yeast cell number were counted on their selection media. The microbes in Mul-kimchi were isolated and identified. Total cell number increased as salt concentration decreased and fermentation temperature increased. Lactic acid bacteria showed the highest number in 1.0% salt concentration. Yeast cell number increased with increase of salt concentration. Lactobacillus sp. were identified Lactobacillus plantarum and L. pentosus in Mul-kimchi containing $0.2{\sim}1.0%$ salt while those of Mul-kimchi containing 3.0% salt were Lactobacillus plantarum and L. brevis. The other lactic acid bacteria were identified Leuconostoc citrum, Leu.mes.ssp.mesenteroides/dextranicum and streptococcus facium in Mul-kimchi containing $0{\sim}3.0%$ salt while Pediococcus sp. was not detected. Gram-negative Aeromonas hydrophila, Pseudomonas fluorescens, Pseu. aureofaciens and yeast Candida pelliculosa, Cryptococcus laurentii were identified in the Mul-kimchi.
