Among cyanobacteria isolated from Northern Adriatic five strains were able to grow on oil refinery wastewater. Based on the sequencing of the internal transcribed spacer (ITS region) and morphological features strains were identified as Synechococcus sp. MK568070, Phormidium lucidum MK568072, Neolyngbia sp. MK568073, Pseudanabaena sp. MK568071 and Spirulina subsalsa MK573248. Selected marine cyanobacteria were tested over a range of ammonium (NH4+) concentrations simulating oil refinery effluent conditions. Three strains demonstrated high growth potential in a range 0.8–2.0 mM NH4+. Maximum biomass concentrations in stationary phase were in a range 176–590 mg/l, whereas total lipid yields were in a range 7.63–21.40% of dry weight. Although all species satisfy the criteria for biodiesel production the average degree of unsaturation was lowest in Synechococcus sp. MK568070 and Neolyngbia sp. MK568073. High proportion of polyunsaturated alpha-linolenic acid found in Spirulina subsalsa MK573248 opens up considerations for nutritional, aquaculture or other biotechnology applications of that species.

亚得里亚海蓝细菌具有潜力,可用于炼油厂废水修复的热电联产生物燃料

从北亚得里亚海分离出的蓝细菌中,有五种菌株能够在炼油厂废水中生长。根据内部转录间隔区(ITS区)和形态特征的测序,菌株被鉴定为Synechococcus sp。MK568070,纤细席灵芝MK568072,Neolyngbia SP。MK568073,Pseudanabaena sp。MK568071和螺旋藻盐沼MK573248。在模拟炼油厂出水条件的一系列铵(NH 4 +)浓度范围内测试了选定的海洋蓝细菌。三种菌株在0.8–2.0 mM NH 4 +范围内显示出高生长潜力。固定相中最大生物量浓度为176–590 mg / l,而总脂质产量为干重的7.63–21.40%。尽管所有物种均满足生物柴油生产的标准,但Synechococcus sp。的平均不饱和度最低。MK568070和Neolyngbia sp。MK568073。在螺旋藻MK573248中发现高比例的多不饱和α-亚麻酸,为该物种的营养,水产养殖或其他生物技术应用提供了考虑。
