Cellulomonas sp. KL-6 균주의 균체내 외 단백질은 배양 5일째에 $266;{mu}g/m{ell},;37;{mu}g/m{ell}$로 가장 많이 생산하였다. 본 실험에서 사용한 KL-6 균주는 볏짚을 분쇄 후 1.0% NaOH와 10% $NH_4OH$로 $80^{circ}C$에서 30분간 처리한 후 $H_3PO_4$로 중화하여 탄소원으로 이용하였을 때 각각 $1.63;g/{ell}$ 및 $1.47;g/{ell}$의 SCP가 생산되어 처리하지 않은 볏짚의 $0.5;g/{ell}$ 보다 균체수율이 증가되었다. KL-6 균주가 생산한 SCP의 필수아미노산의 함량이 FAO 표준단백질에 비해 많아 영양적 가치가 매우 우수하였다. 그러나 실제 동물사육에 이 균체를 이용코저 할 때는 균체의 세포벽을 파쇄후 사용해야 되리라 사료된다.
Experiments were carried out to find out the optimal condition of SCP produced by Cellulomonas sp. KL-6 and to evaluate nutritional value for the protein of this organism Intracellular- and extracellular proteins produced by this strain were estimated to be nearly maximum, $266;{mu}g/m{ell};and;37;{mu}g/m{ell}$, in the medium containing 0.001% of thiamin after 5 days cultivation. When used rice straw as carbon source for the cell growth of this organism after crusing them by cutting mill, and treating them with 1.0% of NaOH and 10.0% of $NH_4OH;at;80^{circ}C$ for 30 minutes and neutralizing continuatively them with 85% of $H_3PO_4$, SCP production rates were very increased to $1.63;g/{ell}$ (NaOH) and $1.47;g/{ell}$ (NH4OH), respectively than $0.5;g/{ell}$ produced in untreated rice straw. We compared their amino acids patterns with that of FAO provisional patterns. Amino acids content of strain KL-6 was excellents. However. when intended these cell mass to use in practical animal feeding test it would be advisable that destruction or lysis of cell wall should be done.
