Abstract

The plant pathogenic bacterium Xanthomonas campestris is a Gram-negative, rod-shaped bacterium that causes damage to plant leaves. This particular disease can result in significant economic losses and a reduction in the quality of agricultural products. An alternative method of dealing with this bacteria is to utilise the rhizosphere of kale (Ipomoea carnea) as a biological control. The objective of this study was to ascertain the antibacterial potential of the rhizosphere bacteria of kale (Ipomoea carnea) against the Xanthomonas campestris bacteria and to identify isolates with enhanced antibacterial efficacy against Xanthomonas campestris using the well diffusion method. A total of 13 bacterial isolates were obtained from the rhizosphere of kale, exhibiting distinctive round colonies, flat edges, and a white or cream colouration. A total of 12 gram-negative isolates and one gram-positive isolate were identified. The highest inhibitory activity against X. campestris was demonstrated by isolates R1, R3, and R11, with an average inhibitory zone diameter of 20.01 mm, 20.79 mm, and 20.57 mm, respectively. These values fell into the very strong inhibition category.

Abstract

Belut adalah kelompok ikan berbentuk mirip ular yang termasukdalam suku Synbranchidae. Bakteri pada kelompok ikan seperti belut dapatdijumpai pada permukaan tubuh dan saluran pencernaan. Sebagian bakteribersifat patogen, sedangkan sejumlah bakteri lainnya menguntungkan,namun penelitian yang mengkaji hal ini belum optimal.Penelitian inimengkaji komposisi bakteri saluran pencernaan belut rawa (Synbranchusbengalensis) menggunakan metode eksploratif deskriptif. Hasil penelitianmenunjukkan bahwa komposisi bakteri yang terdapat pada saluranpencernaan belut rawa bersifat beragam namun didominasi oleh bakterigram positif; BR2, BR3, BR4, BR5. Selain itu beberapa bakteri tersebut masukkedalam kelompok bakteri proteolitik; BR2 dan BR4, bakteri lipolitik BR2,dan bakteri amilolitik ;BR1 dimana bakteri peghidrolisis enzim pencernaantersebut dapat berperan sebagai probiotik dalam saluran pencernaan belutrawa (Synbranchus bengalensis).
