Abstract

An exploration study of natural resources soil bacteria antibiotic-producer, Streptomyces spp. was done in two steps. The first step was isolation of Streptomyces and the second involved testing their inhibition activities against five strains diarrheagenic Escherichia coli. Soil samples were collected from ten forest areas in Bali. As many as 55 isolates were collected with various macroscopic dan microscopic characters. Most isolates (eight Streptomyces isolates) were collected from forest area in Penulisan, Kintamani (RTK. 20). The diversities of isolates are influenced by environment condition. All Streptomyces isolated were tested against five strains diarrheagenic Escherichia coli to check antibiotic activity for inhibit growth of E. coli. Streptomycine was used as a control. The result showed that the largest inhibition zones of Streptomyces against E. coli strains EHEC, ETEC, EIEC, EPEC and DAEC were produced by Streptomyces PK5 (48,67 ± 0,58 mm), Streptomyces GAA4 (29,00 ± 2,00 mm), Streptomyces GBK3 (42,67 ± 2,08 mm), Streptomyces SkBB5 (29,00 ± 2,65 mm) and Streptomyces GM3 (33,67 ± 3,21 mm) respectively.

Abstract

Freshwater prawn (Macrobrachium rosenbergii (de Man)) farming in Bali needs to be supported by the provisionof healthy prawn larvae. Vibriosis infection can be a limiting factor on larval production system which cause highmass mortality in larvae. Therefore a bacteriological study is very important to identify of Vibrio species whichcan cause vibriosis in freshwater prawn larvae. Screening of Vibrio bacteria carried on larval rearing water atUPT Pembenihan Dinas Kelautan dan Perikanan Provinsi Bali which located in Pesinggahan Village, Klungkung.During study, 5 Vibrio isolates can be characterized (VSP01, VSP02, VSP04, VSP05 and VSP06) which wereisolated as dominant Vibrio bacteria in larval rearing water. Koch postulate test results showed that VSP06 cancause vibriosis in freshwater prawn larvae. The result of identification by BBL Cystal™ Identification Systems andidentification book Bergeys’s Manual of Determinative Bacteriology Ninth Edition (Holt et al., 1994), BL6 wasidentified as Vibrio anguillarum.

Abstract

Telah dilakukan penelitian yang bertujuan mengetahui ketahanan Rhizobium sp. yang ditumbuhkan pada pH media pertumbuhan 7,0 dan 5,8 serta mengetahui kemampuan hidup Rhizobium sp. pada media tanah asam dengan pH 5,0 dan respon inokulum Rhizobium sp. pada tanaman kedelai secara in vivo. ATR (Acid Tolerance Responce) didapatkan dengan cara menumbuhkan Rhizobium sp. dengan pH media pertumbuhan 7,0 dan ditambahkan dengan media YMB (Yeast Extract Mannitol Broth) dengan pH 5,8 dan pH 7,0, diinkubasi pada suhu 280C selama 24 jam pada shaker. Penghitungan total mikroba dilakukan setiap 2 jam sekali dengan menggunakan platting method. Uji ketahanan Rhizobium sp. pada tanah asam dengan pH 5,0 secara in vitro dengan cara menghitung total bakteri dengan menggunakan platting method setiap hari selama 28 hari. Uji in vivo dilakukan dirumah kaca dengan menggunakan metoda MPN (Most Probable Number). Hasil penelitian menunjukkan Rhizobium sp. yang dikondisikan pertumbuhannya dengan pH 5,8 lebih resisten dan dapat membentuk ATR dibandingkan dengan Rhizobium sp. yang ditumbuhkan pada pH media 7,0. Pada pH 5,8 setelah 10 jam total bakteri 285 CFU/g sedangkan pada pH 7,0 total bakteri 148 CFU/g. Rhizobium sp. mampu hidup pada tanah asam dengan pH 5,0 dan membentuk ATR pada hari ke 6 dengan total bakteri 137 x 104 CFU/g, tetapi respon inokulum Rhizobium sp. pada tanah dengan pH 5,0 tidak terjadi pembentukan nodul pada tanaman kedelai dikarenakan tanaman kedelai mengalami defisiensi unsur hara.
