对绿藻葡萄球菌产生的液态碳氢化合物和脂肪酸的结构进行了鉴定。对该藻类的两个代表菌株IPPAS H-252和首次从什拉湖分离得到的菌种进行了鉴定。布氏杆菌H-252菌株的脂肪酸组成以C16-C18系列三烯酸含量较高为特征。该菌株的烃类组成以直链和支链C14-C28组分为主，其中长链直链脂肪族C20-C27烃占54.4%，2，6，10，14-四甲基十六烷占20.5%。H-252菌株在脂肪酸和碳氢化合物组成上与早先描述的布氏葡萄球菌不同。葡萄球菌分离株的脂肪酸组成主要由C12-C32饱和脂肪酸和单烯酸组成。该菌株形成的碳氢化合物由二烯和三烯组成。C23-C31二烯烃中以C29(48.9-56.3%)和C31(11.1-16.3%)为主，C27、C29和C31三烯烃占总烃的2.5-2.6%。这类碳氢化合物和脂肪脂肪酸组成是布氏巴氏杆菌A小种的特征。
The structure of liquid hydrocarbons and fatty acids produced by the green alga Botryococcus was identified. Two representatives of this alga, Botryococcus braunii Kütz, strain IPPAS H-252, introduced into culture earlier and an organism isolated for the first time from the Shira Lake, were used for this identification. Fatty acid composition of B. braunii, strain H-252, lipids was characterized by a high content of trienoic acids of C16–C18 series. The hydrocarbon composition of this strain was represented by straight-chain and branched-chain C14–C28 components; long-chain linear aliphatic C20–C27 hydrocarbons (54.4%) and 2,6,10,14-tetramethylhexadecane (20.5%) predominated among them. The strain H-252 differed in its fatty acid and hydrocarbon composition from the strains described earlier as Botryococcus braunii. The fatty acid composition of the Botryococcus isolate was represented mainly by C12–C32 saturated and monoenoic acids. The hydrocarbons formed by this isolate were represented by dienoic and trienoic components. C29 (48.9–56.3%) and C31 (11.1–16.3%) hydrocarbons predominated among the C23–C31 dienoic hydrocarbons, and C27, C29, and C31 trienoic hydrocarbons comprised 2.5–2.6% of total hydrocarbons. This type of hydrocarbons and the lipid fatty acid composition were characteristic for the race A of B. braunii.
