Abstract
AbstractAn assessment of the physical–chemical (pH, Eh), some chemical (content of chloroform-extractable substances and total petroleum hydrocarbons) and microbiological (hydrocarbon-oxidizing, thionic and sulfur-reducing bacteria) parameters of the bottom sediments of the coastal water area of the Kazantip Nature Reserve (Azov Sea) was done in the period from 2013 to 2016. According to the results obtained, the bottom sediments of the coastal water area of Kazantip Cape were conditionally clean, with the exception of the lake—Neftyanikov Lake, located in the center of the Reserve. The concentrations of chloroform-extractable substances in this lake fluctuated from 70 to 170 mg/100 g air-dry bottom sediments. The number (cell/g) of heterotrophic bacteria ranged from 105 to 107, respectively, hydrocarbon-oxidizing—from 1.0 to 104, thionic—from 4.5·102 to 2.5·105, sulfur-reducing—from 1.0 to 1.5·103. This evidenced of the high degree of development of the heterotrophic bacterial community, including hydrocarbon-oxidizing bacteria in shallow stations of the water area.KeywordsPhysical–chemical parametersOrganic matterBacteriobenthosSea bottom sedimentsKazantip Nature ReserveAzov Sea
