gel형성 다당류 생산균주인 Pseudomonas elodea ATTC 31461의 배양조건을 검토하기 위하여 탄소원, 질소원, 온도, pH의 영향을 조사한 결과 적당한 온도는 $30^{circ}C$, pH는 6.5이고, 배지조성은 포도당 25g/L, peptone 12.38g/L, $K_2HP04$ 0.5g/L, MgSO4.7H20 0.1g/L이 적합하였으며 이때 다당류의 생성량은 32g/L이었다. 생산다당류의 1% 용액은 점도가 837mPas, 점조성지수는 2570mPas, 유동지수는 0.66이다.
Cultural conditions for the polysaccharide production by Pseudomonas elodea ATCC 31461, a thermogellable polysaccharide producer, were investigated. Optimum condition for polysaccharide production were: temperature; $30^{circ}C$, pH; 6.5, glucose; 25 g/L. nitrogen source; peptone, C/N ratio; 5.0. Maximum production and yield at this condition were ca. 32 g/L and 128%, viscosity of 1% polysaccharide solution was 837 mPas at 35/sec.. Consistency index and flow behaviour index were 2570 mPas and 0.66
