Isolasi Bakteri Pendegradasi Phenanthrene dari Batanta-Salawati Raja Ampat Papua
ABSTRACT: Isolation of
Bacteria Degrading Phenanthrene in Batanta- Salawati Districts Raja Ampat Papua.
Polycyclic aromatic hydrocarbons (PAHs) are important environmental
contaminantsin soil and water. These compounds have a potential risk to human
health, as many of them arecarsinogenic and toxic to marine organisms such as
diatome, gasthrophode, mussel, and fish.Phenanthrene is one of the hazardous
hydrocarbon compounds. The purpose of this researchwas to characterize
microbial strains from Batanta-Salawati Raja Ampat Papua Island and theirability
to remove phenanthrene. Two isolates were identified at their physiological
characteristicsbased on salinity tolerance, pH tolerance and the composition of
nitrogen base. Molecularidentification based on 16S rRNA gene sequences
indicated that bacteria had the highestsimilarity with Rhodobacteraceae
bacterium F9 and Roseobacter sp. RW 37. Rhodobacteraceae bacterium F9 could
grow optimum on ONR7a media with 5% salinity andat pH of 5-7,5 while
Roseobacter sp. RW 37 could grow optimum on ONR7a media with 2% salinity and at
pH of 6,2-7,5.
