Rhodopseudomonas capsulata H161에 다량 축적되어 있는, 천연 색소 자원으로 중요한 carotenoid 색소 생성조건을 검토하기 위하여 본 실험을 행하였다. Rhodopseudomonas capsulata H161이 생성하는 주된 carotenoid는 spheroidene, rhodovibrin, spirilloxanthin, lycopene이었다. 본 균주는 anaerobic light, 온도 30℃, pH 7.4, 광도 5, 000Lux에서 5일간 배양하였을 때 균체 생성과 carotenoid 생성량이 최대치를 보여주었다.

The photosynthetic bacteria, Rhodopseudomonas capsulata H161, were grown anaerobically in the Modified Ormerod medium for 5 days. The optimun temperature and pH for growth and carotenoid pigment of the organism were observed at 30℃, and around pH 7.4, respectively. The optimum condition of producing the carotenoid pigment, light intensity 5, 000 lux. The photosynthetic bacteria, Rhodopseudomonas capsulata H161, produced large amount of carotenoid pigment, which were identified to 4 carotenoid components containing ; spheroidene, rhodovibrin, spirilloxanthin, lycopene.
