ISOLASI BAKTERI LAUT DARI PERAIRAN MALALAYANG, SULAWESI UTARA
Abstract
Marine bacteria have a lot of potential in exploring the enzyme that can be developed, such as a producer of proteorhodopsin, act as hydrocarbon chlorlastic and can degrade oil. This study aims to obtain isolates and can characterize the bacterial morphology. Malalayang Waters is one of the marine bacterial habitats that has potential area to be studied. This study aims to isolate marine bacteria from Malalayang Waters. These marine bacteria first were diluted into sea water before they were grown on Nutrient Agar (NA). Based on the results of this study it was found that marine bacterial isolated were separated based on their morphological characteristics. The dominant morphological characteristics were yellow whites which dominant shape were irregular.
Keywords: bacterial, dilution, isolation.
Bakteri laut memiliki banyak potensi yang dapat dikembangkan. Seperti penghasil proteorhodopsin, berperan sebagai hidrokarbonoklastik dan dapat mendegradasi minyak. Perairan Malalayang merupakan salah satu habitat bakteri laut yang belum diteliti. Penelitian ini bertujuan untuk mengisolasi bakteri laut dari Perairan Malalayang. Bakteri laut ditumbuhkan pada media agar + air laut, selain itu bakteri juga dilakukan pengenceran terhadap air laut sebelum bakteri ditumbuhkan pada media Nutrient Agar (NA). Berdasarkan hasil penelitian ini isolat bakteri laut ditemukan, bakteri tersebut dipisahkan berdasarkan karakteristik morfologinya. Karakteristik morfologi yang dimiliki dominan berwarna putih kuning dan memiliki bentuk yang dominan tidak teratur. Hal ini dapat memperlihatkan perbedaan bakteri laut dari Perairan Malalayang yang tumbuh.
Kata kunci: bakteri, pengenceran, isolasi.
