Abstract

Of 1,100 yeast strains which were isolated from various Korean fermented foods, screened for phosphate solubilization, five strains showed the ability to solubilize tricalcium phosphate. The 26S rDNA domain D1-D2 sequence analysis revealed the identification of strain Y393 and Y524 as Pichia anomala (99.8 and 100% identity, respectively), Y669 as Pichia farinosa (100% identity), Y901 as Candida versatilis (100% identity), and Y1101 as Pichia subpelliculosa (100% identity). All the phosphate solubilizing strains showed mesophilic characteristics. The temperature range for growth of 4 strains was $20{\sim}35^{\circ}C$ and P. farinosa Y669 was able to grow up to $45^{\circ}C$. The strain C. versatilis Y907 was able to grow at pH range of 5.0~6.0 and showed halophilic characteristics with tolerance to 15% of NaCl concentration. The Phosphate solubilizing yeast strains were survived well in bed soil for 8 weeks which were maintained densities of $10^7{\sim}10^8$ cfu/g. The highest phosphate solubilizing activity was observed in P. subpelliculosa Y1101. It solubilized 697.2 ug/mL of phosphorus from tricalcium phosphate with decrease in pH from 6.8 to 4.37 after 11 days of inoculation.

한국 전통 발효식품에서 분리한 효모로부터 인산 가용화 활성이 우수한 5균주를 선발하였다. 선발한 균주 중 2균주는 Pichia anomala로 동정되었고, 3균주는 각각 Pichia farinosa, Candida versatilis, Pichia subpelliculosa로 동정되었다. 인산 가용화 효모는 $20{\sim}35^{\circ}C$의 온도에서 잘 자라는 중 온성 효모였으며 P. farinosa Y669는 $45^{\circ}C$의 고온에서도 생장하였다. C. versatilis Y907 균주는 pH 5~6의 좁은 pH 범위에서 생장하였고 15%의 NaCl 농도까지 내성을 나타내는 호염성 균주였다. 그 외 4균주는 pH 4.0~8.0에서 생장하였으며 NaCl 10% 농도에서 내성을 나타내었다. 인산 가용화 균주는 토양에서도 8주 동안 $10^7{\sim}10^8$ cfu/g의 밀도를 유지하며 생존하였다. 분리균주 중 인산 가용화 활성은 P. subpelliculosa Y1101가 가장 우수하였으며 배양 11일 후 697.2 ug/mL의 유리인산을 생성하였다.
