摘要
研究了沼泽红假单胞菌适宜培养条件下番茄红素的含量 .结果发现 ,在厌氧、30℃条件下 ,培养基中加入Fe3 + 0 .0 1gL-1,有利于提高番茄红素的含量 ;培养基中Mg2 + 浓度对其产量影响不显著 ;当光照强度为 2 0 0 0lx时培养的菌体中番茄红素的含量最高 ,处于生长稳定初期 (6d) ,沼泽红假单胞菌中番茄红素的积累量可达 5 3.7μgmg-1.图 3表 1参
The possibility of lycopene accumulation in some culture conditions was studied using photosynthetic bacteria(PSB),Rhodopseudomonas palustris. Some metal ions, such as Fe 3+ and Mg 2+, were added in culture medium, and the PSB was cultured under varied light intensity for several days. It was found that the yield of lycopene was increased when 0.01g L -1 of Fe 3+ added and lycopene yield would reach a maximum of 53.7 μg mg -1 if the PSB was cultured under light intensity of 2 000 lx for 6 days.
