Abstract

Cellulosic single cell proteins produced from rice straw by three strains of cellulolytic bacteria were analysed for their composition and for their amino acid patterns. It was showed that they contains 52.2∼70.3% of crude Protein, 11.6∼13.9% of crude fat and 11.5∼18.1% of ash. The sulphur containing amino acids and threonine were analysed to be the limiting amino acid in the cellulosic SCP. The protein scores were calculated as 80.0 for Cellulomonas flavigena KIST 321, 78.00 for Cellulomonas fimi and 61.8 for Cellulomonas aurogena KIST 11. The nutritional value of the cellulosic SCP is discussed from the results.

볏짚을 기질로 생산한 삼종의 단세포단백질의 성분 및 아미노산의 조성을 분석하였다. 이들의 조성을 조단백질 52.2∼70.3%, 조지방 11.6∼13.9%, 회분 11.5∼18.1% 이었으며, 단백가는 80.0, 61.8, 78.0이였다. 이 결과를 바탕으로 이들의 단백질원으로의 가치를 검토하였다.
