Abstract

The aim of this experiment was to characterize A. versicolor 3a1 α-amylase produced on cassava liquid waste media. Two types of media, base and combination media, were used as a comparison. Cassava liquid waste media contains 1% cassava starch, 1% yeast extract, 0.13% KH2PO4, and 0.05% MgSO4 diluted in cassava liquid waste. Base media contains same composition but using aquadest as a solvent, and combination media using mixture of aquadest and cassava liquid waste. A. versicolor 3a1 α-amylase showed its maximum specific activity in cassava liquid waste, base, and combination media after 3, 7, and 4 days incubation, respectively. Crude extract of α-amylase fromA. versicolor 3a1 was precipitated in 20-80% (w/v) ammonium sulphate. Precipitation of A. versicolor 3a1 α-amylase with 70% (w/v) ammonium sulphate on cassava liquidwaste, 60% on base media, and 60% on combination media will increase its specific activity 16.6, 4.28, and 5.65 times, respectively, compared to the specific activities ofcrude before precipitation. α-Amylase crude extract from A. versicolor 3a1 from all media showed its highest specific activity at 70oC and pH 5.0, and addition of FeSO4 increased the specific activity. Precipitated A. versicolor 3a1 α-amylase from all media showed its highest specific activity at 70oC and pH 6.0. Addition of FeSO4 precipitated 3a1 α-amylase from base and combination media will increase its specific activity, while MgSO4 will increase its specific activity in cassava liquid waste media. Thermostability assay revealed that the crude and the precipitated 3a1 α-amylase were relatively stable at 70oC up to 180 minutes incubation, except for precipitated3a1 -amylase on cassava waste media. Crude α-amylase 3a1 was relatively stable at pH 5-9 up to 1 hour incubation with wide pH ranges, while the precipitated with narrow pH ranges.

Abstract

AbstrakBakteri rizosfer adalah bakteri yang terdapat pada daerah perakaran tanaman yang diketahui memiliki keanekaragaman tinggi. Bakteri rizosfer memiliki berbagai peran seperti menyediakan nutrisi bagi tanaman, melindungi tanaman dari infeksi bakteri patogen, menghasilkan hormon pertumbuhan seperti indol acetic acid, pelarut fosfat, pengikat nitrogen, dan lain-lain. Dengan berbagai kemampuan dan peran tersebut, maka perlu eksplorasi bakteri rizosfer tanaman sawit khususnya di daerah perkebunan agar diketahui kelompok bakteri rizosfer, sehingga dapat dimanfaatkan secara optimal. Penelitian ini bertujuan untuk mengetahui kelompok dan keragaman bakteri rizosfer pada tanaman sawit yang berumur 8, 11, dan 14 tahun. Penelitian dilakukan dengan pendekatan konvensional dengan karakterisasi morfologi dan uji biokimia. Dari umur-umur tersebut, didapatkan 18 isolat yang terdiri dari 11 genus, yaitu Bacillus, Azospirillum, Actinobacillus, Xanthobacter, Enterococcus, Paenibacillus, Klebsiella, Pseudomonas, Arthrobacter, Micrococcus, dan Streptococcus. Bakteri rizosfer tanaman sawit memiliki keragaman genus yang sama pada umur 8, 11, dan 14 tahun. Genus bakteri yang didapatkan dapat dimanfaatkan sebagai PGPR (Plant Promoting Rhizobacteria).Abstract Rhizosphere bacteria are bacteria found in root areas. Rhizosphere bacteria have various roles such as providing nutrients for plants, protecting plants from infection pathogenic bacteria, producing growth hormones such as indol acetic acid, phosphate solvents, nitrogen binders, and others. By having these various abilities and roles, it is necessary to explore the bacteria of oil palm plants, especially in the plantation areas so that the group of rhizosphere bacteria can be identified and then utilized optimally. This study aims to determine the group and diversity of rhizosphere bacteria in oil palm plants that are 8, 11, and 14 years old. The research was conducted conventionally by observing morphological and biochemical characterization. At those ages, 18 isolates were consisting of 11 genera, namely Bacillus, Azospirillum, Actinobacillus, Xanthobacter, Enterococcus, Paenibacillus, Klebsiella, Pseudomonas, Arthrobacter, Micrococcus, and Streptococcus through conventional methods. Rhizosphere bacteria in oil palm plants have the same genus diversity at the ages of 8, 11, and 14 years. The bacterial genus obtained can be used as PGPR (Plant Promoting Rhizobacteria).

Abstract

Limbah cair kelapa sawit merupakan limbah organik yang memiliki kandungan kompleks seperti air, minyak dan padatan organik. Kandungan organik limbah cair kelapa sawit menjadi indikasi kelimpahan beragam jenis mikroorganisme. Penelitian ini bertujuan untuk mendapatkan bakteri fotosintetik anoksigenik (BFA) penghasil pigmen karotenoid yang berasal dari limbah cair kelapa sawit. Isolasi dan skrining BFA dilakukan dari tiga lokasi pembuangan limbah cair kelapa sawit yang berada di Provinsi Jambi. Penelitian ini dilakukan dengan metode eksperimental menggunakan media mineral modifikasi. Isolat BFA yang tumbuh dan menghasilkan pigmen karotenoid ditandai dengan adanya distribusi pigmen berwarna kuning kemerahan pada media kultur. Dari hasil skrining diperoleh 11 isolat BFA yaitu Bg1K201, Bg1K202, Bg2k201, Bg3k201, Mr1k201, Mr1k202, Sl1k201, Sl1k202, Sl2k201, Sl2k202 dan Sl3k202. Hasil karakterisari ciri morfologi dan sifat fisiologi berdasarkan Bergeys Manual of Determinative Bacteriology menunjukkan bahwa dari kesebelas isolat BFA didapatkan 2 jenis genus BFA yang tergolong gram negatif dan memiliki pigmen karotenoid yaitu genus Rhodobacter (Bg1k201, Bg1k202, Bg3k201, Sl1k201, Sl1k202, Sl2k201, Sl2k202 dan, Sl3k202) dan genus Rhodopseudomonas (Bg2k201, Mr1k201 dan Mr1k202).Palm liquid sewage is organic waste that contains complex compounds such as water, oil, and organic solids. The organic content of palm liquid sewages is an indication of the abundance of microorganisms. This study aims to obtain anoxygenic photosynthetic bacteria (BFA) that produce carotenoid pigments from palm liquid sewages. Therefore, We isolated and screened of BFA from three palm liquid sewage disposal sites in Jambi Province. This research was conducted by an experimental method using a modified mineral medium. BFA isolates that growth and produced carotenoid pigments are visible because of the distribution of reddish-yellow pigments on the culture media. Screening results obtained 11 isolates of BFA sequentially Bg1K201, Bg1K202, Bg2k201, Bg3k201, Mr1k201, Mr1k202, Sl1k201, Sl1k202, Sl2k201, Sl2k202 and Sl3k202. The results of morphological and physiological characterization based on the Bergeys Manual of Determinative Bacteriology show that there are two types of BFA genera that have carotenoid pigments, respectively, the genus Rhodobacter (Bg1k201, Bg1k202, Bg3k201, Sl1k201, Sl1k202, and Sl1k202, and Sl2k202, and Sl1k202, and Sl2k202, and Sl1k202 and Sl2k202, and Sl2k202, and Sl2k202. Sl2k202, and) the genus Rhodopseudomonas (Bg2k201, Mr1k201 and Mr1k202).

Abstract

Aktinobakteri merupakan salah satu agen hayati yang mampu menghambat jamur patogen pada tanaman. Aktinobakteri mampu menghasilkan enzim kitinase untuk menghidrolisis dinding sel jamur sehingga menghambat pertumbuhan jamur patogen. Tujuan dari penelitian ini adalah untuk mengevaluasi kemampuan enzim kitinase dari aktinobakteri dari beberapa sumber tanah di Provinsi Jambi yang dapat menghambat jamur patogen tanaman Ganoderma boninense penyebab penyakit busuk pangkal batang kelapa sawit. Isolat diremajakan pada media starch nitrate agar, produksi kitinase dilakukan menggunakan koloidal kitin yang diperkaya, dan pengukuran aktivitas kitinase aktinobakteri dilakukan dengan menggunakan N-asetil glukosamin (GlcNAc) sebagai standar kitinase dan dibaca dengan spektrofotometer UV-VIS pada λ 584 nm. Isolat yang digunakan berasal dari dua jenis tanah yang berbeda, yaitu tanah perkebunan kelapa sawit (S16) dan tanah gambut (KT4). Hasil uji kualitatif menunjukkan nilai indeks kitinolitik S16 sebesar 1,90 dan KT4 sebesar 1,75. Uji aktivitas enzim kitinase dari kedua isolat diperoleh nilai 0,030 U/ml untuk isolat S16 dan 0,027 U/ml untuk isolat KT4. Uji penghambatan terhadap bakteri patogen Ganoderma boninense diperoleh daya hambat sebesar 54,33±1,53 dan 41,00±1,41 untuk isolat S16 dan KT4. Penelitian ini menyimpulkan bahwa aktinobakteri memiliki potensi untuk mengendalikan pertumbuhan Ganoderma boninense.
