This paper shows the oil-oxidizing ability of Micrococcus bacteria isolated from the Nakhodka Bay surface waters of the Peter the Great Gulf, the Sea of Japan. Micrococcus Bacteria are known to be the most active destructors of petroleum hydrocarbons in natural biotopes, contaminated objects. Voroshilova-Dianova liquid containing 2,5% oil or oil products was introduced into sterile penicillin bottles with 105 cells of the investigated bacteria. The ability to destruct petroleum hydrocarbons by bacteria of this genus was studied using a gravimetric method during 30 days. Destruction of oil, gasoline, fuel oil and diesel fuel was shown. Micrococcus bacteria showed a high oil-oxidizing ability and decompose 65-99,9% of oil and oil products within 30 days. Gasoline was the source of petroleum hydrocarbons with the greatest ability to utilize this genus of bacteria. The destruction of this hydrocarbons source by bacteria on days 15-20 was about 99% of the initial concentration. The lowest ability of destruction by Micrococcus bacteria was revealed for diesel fuel.

The Oil Refinery of Heydar Aliyev was created in July 1953 as a new oil refining plant Baki. The combined atmospheric vacuum plant is the main plant at the oil refining factory and its starting capacity produces 6 million tons of crude oil. In 2010, 43,000 tons A-98, 1.18 tons of A-92 and 19,700 tons of gasoline A-80. At the same time, 600 400t kerosene, 214,000 diesel fuels, 214,000 tons. Liquid gas, 267 500t coke and 220 600t. With this investigation, the history of the oil refinery and the details of modernization were considered. 21 out of 24 types of Azerbaijani oil are processed at the Baku Oil Refinery named after Heydar Aliyev, of which 15 types of oil products, including gasoline, aviation kerosene, diesel fuel, fuel oil, petroleum coke, etc. are produced. The plant fully meets the needs of the republic in oil products. In addition, 45% of oil products are exported to foreign countries. Key words: Azerbaijani, oil, recycling, factory, modernization

First Finding

Myrianida convoluta (Cognetti) is described from the Bay of Peter the Great. The atokous form, stolon-bearing specimens and female with larvae were found in August 2006 on sea grasses from the depth of 1-2 m. The species is recorded from the Russian seas for the fi rst time.

The sublittoral hermit crab Pagurus trigonocheirus (Stimpson, 1858) (Crustacea: Decapoda: Paguridae) is recorded from depths of 80–200 m along the continental coastline of the Peter the Great Bay, Sea of Japan. The exact sampling localities as well as photographs of live specimens are presented in the paper. Doubtful records of hermit crabs from the southern Russian coastline of the Sea of Japan are also discussed.

A description of one new, and redescription of one known, species of the subfamily Adoncholaiminae (Nematoda: Oncholaimidae) from Peter the Great Bay (Sea of Japan) are provided. Adoncholaimus ussuriensis sp. n. is characterised by relatively large body size (L = 4.3-5.8 mm in male, 4.4-6.2 mm in female), a pair of terminal pores of the Demanian system opening dorsally at 147-189 μm (2.3-3.0 abd) anterior to the anus, excretory pore located posterior to buccal cavity region, absence of a ventral swelling on tail, long spicules (190-230 μm), presence of a gubernaculum (32-40 μm), presence of a complicated sensory field in the male with a complex supplementary organ and two sets of pilose filaments (5-10 μm long) on the posterior cloacal lobe and four rows of subventral and subdorsal postcloacal sensilla. We provide a redescription of Admirandus multicavus illustrated by light and scanning electron micrographs and propose Adoncholaimus chinensis as a junior synonym of Admirandus multicavus. The diagnoses of both genera are emended. Partial sequences of the mitochondrial gene cytochrome oxidase c subunit I (COI) and D2-D3 region of the 28S rDNA for both species were obtained. A dichotomous key to Adoncholaimus species is provided.
