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.

Abstract

Bacteria are found to be highly associated with various marine organisms, such as sponges. Sponges are known as the product of bioactive compounds. However, some of the compounds produced by sponges are obtained by the simbion-bacteria. Therefore this situation enables sponges simbion bacteria to play a major role in producing bioactive compounds that have been isolated from the sponge. The purpose of this study is to isolate and determine the characteristics of morphology of spongy simbion bacteria resembling Cribochalina sp, which was taken from Malalayang waters, North Sulawesi. Sponge simbion bacteria grow on NB media. Initially, a free-breeding colony was being done before bacteria were accrued in the NA media by 2% sponge broth (patent SID201906301) by means of Strike Plate methods. Based on to this study we had isolate five spongy simbion bacteria that resembling the Cribochalina sp. All five of these isolations have different characteristics of morphology in terms of color, shape, size, and elevation.      Keywords : bacteria, isolation, simbionts, sponges
