Isolasi dan aktivitas antibakteri jamur endofit pada mangrove Sonneratia alba dari Tanjung Carat Kabupaten Banyuasin Sumatera Selatan

Abstract

S. alba is a mangrove that is commonly found on the east coast of Banyuasin. Endophytic fungus can produce a functional compound e.g antibacterial. The purpose of this study is to determine the type, the increase in diameter of colonies and the antibacterial potential in endophytic fungus of S. alba. The research method used were by the isolation of endophytic fungus from leaf, stem and root, the identification of endophytic fungus, the measurement of colony diameter in endophytic fungus and antibacterial activity test using paper disc method. The results of this study found the two genera of endophytic fungus with four species of Aspergillus sp1., Aspergillus sp2., Paecilomyces sp1., and Paecilomyces sp2. The increase in diameter for each colony of endophytic fungus shows the difference every day. These four types of endophytic fungus are resistant to bacteria E. coli and S. aureus. Aspergillus sp2. endophytic fungus has the highest inhibitor potency of 14.49 mm in E. coli bacteria. The endophytic fungus Paecilomyces sp2. inhibits bacterial growth of S. aureus with the highest inhibitory potency of 11.61 mm.

Investigated of marine endophytic fungi Aspergillus terreus extract’s antibacterial activity against Salmonella Typhimurium

“…The fungal exponential phase begins on the ninth day of cultivation. The exponential phase is important in the life of fungi because there is a lot of cell multiplication, and cell activity is significantly increased [25]. The start of the stationary phase of the exponential phase, produces secondary metabolite products from fungi with the most incredible intensity.…”

Isolasi dan Karakterisasi Jamur dari Sedimen Mangrove Tapak, Semarang

“…Karakterisasi dilakukan dengan melakukan pengamatan secara makroskopik. Pengamatan makroskopik mengacu pada penelitian Mukhlis et al (2018) yang meliputi warna dari permukaan koloni, tingkat dan arah pertumbuhan koloni, tekstur koloni serta elevasi dari koloni jamur.…”

Actinomycetes yang diisolat dari mangrove Rhizophora apiculata di perairan Tanjung Api-api, Sumatera Selatan

“…Bakteri endofit yang hidup pada suatu tanaman dapat menghasilkan senyawa bioaktif yang sama seperti yang terkandung pada tanaman inangnya, hal tersebut dikarenakan adanya rekombinasi genetik yang terjadi antara tanaman inang dengan bakteri endofit pada waktu evolusi (Tan dan Zou, 2001; Heirina et al 2020). Banyak senyawa baru yang ditemukan dari Actinomycetes telah terbukti sebagai obat baru yang potensial dalam bidang industri medis dan farmasi seperti antibiotik, antimikroba, antibakteri, antikanker dan antijamur (Butler, 2004;Rozirwan et al 2020).…”
