Accumulation of Aluminum to Lactic Acid Bacteria under Anaerobic Conditions
혐기조건하 젖산균에서 알루미늄의 축적
Abstract
Present study was investigate to evaluate the aluminum absorption effect on lactic acid bacteria(Lactobacillus acidophilus ATTC 4356, Lactogacillus bulgaricus ATTC 11842, Lactobacillus casei IFO 3533, and Streptococcus thermophilus KCTC 2185 ; LAB) and Clostridium perfringens ATCC 3627 (CP) in artificial intestinal tract. Their growth rate, aluminum accumulation and cellular distribution was studied under anaerobic broth system. All of above microbes were inhibited by adding 10 to 100ppm of aluminum. The degree of aluminum in LAB (Lactobacillus acidophilus ATCC 4356, Lactobacillus bulgaricus ATCC 11842, Lactobacillus casei IFO 3533, and Streptococcus thermophilus KCTC 2185) was higher than of CP. The largest amount of aluminum was accumulated in Lactobacillus bulgaricus ATCC 11842. Aluminum accumulation in LAB was distributed in 49.1% at cell wall, 27.3% at plasma membrane, and 23.6% at cytoplasm, respectively. This study suggests that LAB might help to eliminate the ingested aluminum in intestinal tract.
