![]() ![]() Uji antibiosis menunjukkan se-banyak 33 isolat bakteri endofit menunjukkan daya penghambatan terhadap cendawan Curvulariasp. melalui uji antibiosis dan uji produksi senyawa organik volatil (VOC). Salah satu masalah dalam pembudidayaan kelapa kopyor adalah serangan penyakit bercak kelabu yang disebabkan oleh cendawan Curvulariasp. Penggunaan bakteri endofit merupakan salah satu cara control yang ramah lingkungan.Sebanyak 40 isolat bakteri endofit asal tanaman Arecaceaediisolasi dari tanaman kelapa kopyor, kelapa sawit, aren, nibung dan pejibaye diujikan kemampuan penghambatannya terhadap Curvulariasp. Kelapa kopyor saat ini menjadi salah satu komoditas perkebunan yang penting. The four isolates were isolated from different plants such oil palm, coconut kopyor and pejibaye. Those isolates were molecularly identified as Serratia marcescens strain PIGB81, Burkholderia sp. ![]() Based on the best combination of antibiotic and production of volatile organic compound test, there were four potential isolates to inhibit the growth of Curvularia sp. VOC test showed that EAPJN 216, EAKSS 532, EAAPN 225, EAAPN 506, EAAPN 507 and EAAPN 557 were produced VOC that suppressed the growth of Curvularia sp fungal colonies in a range from 92.27% to 97.21%. ![]() Isolates with the highest inhibition were EAKSS 502, EAKSS 520 and EAKSS 507. in a range of inhibition from 4.4% to 86.6%. The antibiotic test showed that thirty three endophytic bacteria isolates have inhibitory capacity againstCurvularia sp. through antibiotic and volatile organic compound (VOC) test. A total of 40 selected endophytic Arecaceae bacteria isolated from coconut kopyor, palm oil, aren, nibung and pejibaye were tested for their inhibitory ability to Curvularia sp. Using endophytic bacteria is one of the control technique that is environmentally friendly. One of the problems in coconut kopyor cultivation is grey leaf spot disease caused by Curvularia sp. Coconut kopyor is one of the most important commodities. ![]()
