Abstract

With regard to collaboration research called Widya Nusantara Exploration (EWIN) in May-June 2013 and November 2014, a study on isolation of actinomycetes from sediments of Makassar Strait have been conducted. Actinomycetes is one of microbe which has an excellent track record in producing antimikrob and other active substances. But due to terrestrial actinomycetes has been widely explored, then recently researchers began focusing on wide variety of extreme environments, such as marine environment, to screening aktinomisetes in producing new secondary metabolites. A total of 36 strains of actinomycetes were isolated from 10 samples obtained from deepsea floor in Makassar Strait, Indonesia, Direct Dillution Method were best used to isolate the actinomycetes compare to Sodium Dodecyl Sulfida – Yeast Extract Method (SDS-YE Method) and Rehidration Centrifugation Method (RC Method). NBRC-802 media and Actinomycetes Isolation Agar(AIA)(Himedia)media were used as the isolation media. All the isolates were identified by morphological characteristic and by analysis of 16S rRNA gene sequence. Actinomycetes isolated from deepsea floor of Makassar Strait have been dominated by Micromonospora (58%), Verrucosispora (14%)Streptomyces (8%) and Luteipulveratus (5%), however genus Nocardiopsis, Micrococcus, Gordonia, Kytococcus, and Arthrobacter were not dominant (3%). Station 25 in 1.547 m depth was the most abundant of actinomycetes, 18 strains and dominated by the genus Micromonospora which is isolated using Direct Dillution Method and both NBRC 802 or AIA media.

Abstract

Jakarta Bay has been known as one of the most polluted marine environment in Indonesia, with no exception by oil. Seribu Islands waters, located in the north of Jakarta Bay may have been impacted by this polluted condition.It’s sometimes also hit by oil spillage from pipe leakage. The purpose of this study is to isolate and identify hydrocarbonoclastic bacteria (oil and Polyaromatic Hydrocarbon degrading bacteria) from Jakarta Bay and Seribu Island waters. The bacteria were isolated from water and sediment/sand. Isolation was prepared by enriched samples in SWP medium with Arabian Light Crude Oil (ALCO). Screening for PAH degrading bacteria has been completed by using sublimation plate method in ONR7a medium and screening for oil degrading bacteria were conducted by using oil plated method with the same medium. Bacteria identifications were done based on l6sRNA gene. The results were analyzed using BLAST and showed that 131 potential hydrocarbonoclastic bacteria have been isolated from Jakarta Bay and Seribu Island waters. Most of them were oil degrading bacteria (41.98%) and the rest were PAH degrading bacteria. Oil pollution level may impact the number of strain of hydrocarbonoclastic bacteria isolated. Among the hydrocarbonoclastic bacteria isolated from Jakarta Bay and Seribu Islands, Alcanivorax, Marinobacter, Achromobacter and Bacillus were common hydrocarbonoclastic genera in Jakarta Bay and its surrounding waters. Alcanivorax spp. is important oil and PAH-degrader found not only in temperate waters, but in tropical waters as well.
