【摘要】 从湛江市霞山区海滩表层污泥中富集分离出红假单胞菌属光合细菌M-01,对其培养条件进行了初步探讨,结果表明:菌株生长温度为30℃时,最适培养光照度为3000lx。培养基正交试验结果表明其最优培养基配方为:氯化铵2g,磷酸氢二钾0.2g,乙酸钠4g,碳酸氢钠2g,氯化钠1g,酵母膏0.15g,硫酸镁0.2g,T.M储液少量,蒸馏水1000mL;其中乙酸钠为最大影响因子。更多还原

【Abstract】 The photosynthetic bacterium M-01 was isolated from the sludge surface of the beach in Xiashan district of Zhanjiang City and identified as belonging to Rhodopseudomonas. The optimal culture light was 3 000 lx when the growth temperature was 30 ℃. An orthogonal experiment showed that the optimal medium ingredients were NH₄Cl 2 g, KH₂PO₄0.2 g, sodium acetic 4 g, NaHCO₃ 2 g, yeast paste 0.15 g, NaCl 1 g, MgSO₄ 0.2 g, some trace elements （B, Mn, Fe, Mo, Zn）, stilled water 1 000 mL. And sodium acetic was the most influencing factor among the ingredients.更多还原
