Antifungal Activity of Bacillus cereus 11UJ against Rhizoctonia solani and Pyricularia oryzae

Abstract: Metabolit sekunder asal mikrob merupakan sumber senyawa penting untuk pengembangan senyawa anticendawan pada strategi pengendalian penyakit. Penelitian ini bertujuan menguji kemampuan produksi metabolit sekunder bakteri antagonis rizosfer Bacillus cereus 11UJ terhadap cendawan patogen padi Rhizoctonia solani dan Pyricularia oryzae. Efek antagonis ekstrak kasar B. cereus 11UJ diuji dengan metode cakram kertas saring steril pada medium PDA. Ekstrak bakteri dengan pelarut etil asetat menunjukkan aktivitas anticen… Show more

“…In addition, the activity of the enzyme chitinase causes the mushroom cell wall to be lysed (Abidin et al, 2015). The secondary metabolite resulting from the bacteria extract B. cereus 11uj can inhibit the growth of mushrooms R. solani and P. oryzae which is good enough at concentrations of 1,000 ppm, and the antifungal activity produced more effectively inhibits the growth of P. oryzae (Suryadi et al, 2015). One mechanism of emphasis by the endophytic bacteria in the genus Bacillus is antibiosis, through the generation of a bulbiformin antibiotic that is toxic to various plant pathogens (Marsaoli et al, 2019).…”

“…Stated that to achieve the goal of improving productivity, efficiency, and sustainability of farming, the principle of providing accurate nutrients according to plants need (balanced fertilization). The main requirement in the process of making biofertilizer is to find superior microorganisms, for example, can come from bamboo Apus roots (Gigantochola apus) that contain the bacteria Pseudomonas fluorescens and could increase the solubility of P in the soil (Yulistiana et al, 2020), and Bacillus cereus 11UJ isolated from the rhizospheric zone of sugarcane is widely used for antifungal activity tests (Suryadi et al, 2015). Later, these microorganisms can pass through various tests, including the pathogens test, phytohormonal test, and compatibility test.…”

“…Bakteri endofit yang diisolasi dari akar padi gogo di Jawa dan Sumatera menunjukkan reaksi antibiosis terhadap Rhizoctonia solani dan P. grisea pada medium agar dekstrosa kentang (ADK) dan tryptic soy agar (TSA), serta dapat memacu pertumbuhan akar dan tajuk tanaman padi (Munif et al 2012). Bakteri rizosfer Bacillus cereus 11UJ memiliki daya hambat yang kuat terhadap P. oryzae (Suryadi et al 2015). Selain bakteri, cendawan endofit yang diisolasi dari tanaman padi sawah juga mampu menekan perkembangan penyakit blas dengan tingkat penekanan mencapai 70% (Sucipto et al 2015).…”

“…(Nalisha et al, 2006). Didukung hasil penelitian Suryadi et al (2015) bahwa metabolit sekunder yang dihasilkan dari ekstrak bakteri B. cereus 11UJ yakni cyclolanostan dapat menghambat pertumbuhan cendawan R. solani. Khaeruni et al (2011) melaporkan, pencampuran tiga isolat rizobakteri indigenus B. subtilis ST21b, B. cereus ST21e, dan Serratia galur SS29a yang diformulasikan dalam bahan pembawa gambut dan lempung mampu menekan perkembangan penyakit layu fusarium pada tanaman tomat sampai 60%.…”
