Abstract
Relationships of the distribution of petroleum biomarker hydrocarbons (biomarker HCs), namely, n-alkanes, isoprenanes, n-alkylcyclohexanes, steranes, terpanes, and n-alkylbenzenes, in the soluble fraction and in thermolysis products of the insoluble fraction of the biomass of Halomonas titanicae bacteria isolated from the Romashkino crude oil were studied. The relative distribution of biomarker hydrocarbons in the soluble fraction of the bacteria, compared to that in thermolysis products of the insoluble fraction of the bacteria, is closer to that in the crude oil from the Romashkino field. Both in the soluble fraction and in thermolysis products of the insoluble fraction of the Halomonas titanicae bacterial biomass, homologous series of n-alkanes С10–С40, isoprenanes С10–С20, n-alkylcyclohexanes С10–С30, and n-alkylbenzenes С10–С30 were found. Among isoprenanes, pseudoregular C17 isoprenane, which is absent in all crude oils, is also formed. Presumably, it is formed from an irregular isoprenene, squalene, which was detected both in the soluble fraction and in thermolysis products of the insoluble fraction of Halomonas titanicae bacteria. Among cyclic HCs, tetra- and pentacyclic compounds (steranes and terpanes) are formed in all the cases. The values of the pristane/phytane ratio as a genetic parameter and the distribution of regular С27–С29 steranes are close to those in the crude oil from the Romashkino field.

从原核生物生物质中形成石油烃： 4. 从 Romashkino 原油中分离的钛酸卤单胞菌的生物质中形成石油生物标志物烃
摘要
石油生物标志物碳氢化合物（biomarker HCs ），即正烷烃、异戊二烯、正烷基环己烷、甾烷、萜烷和正烷基苯，在可溶部分和不溶部分的热解产物中的分布关系研究了从 Romashkino 原油中分离出的Halomonas titanicae细菌。与细菌不溶部分的热解产物相比，生物标志物烃在细菌可溶部分的相对分布更接近 Romashkino 油田原油中的分布。在钛酸单胞菌的可溶部分和不溶部分的热解产物中发现了细菌生物量，正构烷烃 С 10 –С 40、异戊二烯 С 10 –С 20、正烷基环己烷 С 10 –С 30和正烷基苯 С 10 –С 30的同源系列。在异戊二烯中，还形成了在所有原油中都不存在的假正则C 17异戊二烯。据推测，它是由不规则的异戊二烯角鲨烯形成的，在钛酸单胞菌细菌的可溶部分和不溶部分的热解产物中都检测到了角鲨烯。在环状碳氢化合物中，在所有情况下都会形成四环和五环化合物（甾烷和萜烷）。作为遗传参数的癸烷/植烷比值和常规 С 27 –С 29甾烷的分布与 Romashkino 油田原油中的值接近。
