摘要:

为了研究抗生素种类和浓度对小球藻生物量和相对含油量的影响,并对培养基内蛋白胨和氯化钠含量进行优化,以Chlorella vulgar HDA04为供试藻株,将不同浓度的抗生素添加到培养基中,检测生物量和含油量,并对培养基成分进行优化。结果表明,在初始BG11培养基的基础上添加3种抗生素(卡那霉素、四环素和青霉素),青霉素对Chlorella vulgarHDA04的优化效果最好。且在添加青霉素浓度为1.0 mg/L、氯化钠浓度8 g/L和蛋白胨浓度1.5 g/L时,C. vulgar HDA04的生物量和相对含油量达到最高,其中生物量最高为4.26 ± 0.35 g/L,相对含油量最高为27.04 ± 1.13,较未优化组(初始BG11增殖培养基)提高111%和692.3%。对Chlorella vulgar HDA04培养条件进行优化,奠定了小球藻生产生物柴油的理论基础,对探究高寒盐碱湖地区微藻具有重要意义。

Abstract:

To study the effects of antibiotic types and concentrations on biomass and relative oil content of Chlorella, and to optimize the contents of peptone and NaCl in culture medium, Chlorella vulgar HDA04 was used as the test algae strain, different concentrations of antibiotics were added into the culture medium. The biomass and oil content were detected and the medium composition was optimized. The results showed that three antibiotics (kanamycin, tetracycline and penicillin) were added to the initial BG11 medium, penicillin had the best optimization effect on Chlorella vulgar HDA04. When the concentration of penicillin, sodium chloride and peptone was 1.0 mg/L, 8 g/L and 1.5 g/L, respectively, the biomass and relative oil content of C. vulgar HDA04 reached the highest, and the highest biomass was 4.26±0.35 g/L, and the highest relative oil content was 27.04±1.13, which was 111% and 692.3% higher than control group (initial BG11 culture medium), respectively. Optimizing the culture conditions of Chlorella vulgar HDA04 lays a theoretical basis for biodiesel production by Chlorella vulgar, which has great significance to the exploration of microalgae in the alpine saline lake area.
