Abstract

Aplikasi pupuk hayati yang mengandung mikrob hidup dapat memacu pertumbuhan tanaman. Percobaan dimaksudkan untuk menguji viabilitas Bacillus sp., Pseudomonas sp., Azospirillum sp., dan Azotobacter sp. yang terdapat pada pupuk hayati dikeringkan dengan metode kering beku pada beberapa bulan penyimpanan. Viabilitas sel bakteri diuji setelah disimpan 0, 1, 2, 4, dan 6 bulan. Pupuk hayati tersebut diaplikasi pada tanaman jagung var. Bisma untuk diamati efektivitasnya. Penelitian ini dilakukan di rumah kaca dengan menggunakan metode Rancangan Acak Lengkap (RAL) yang terdiri atas 8 perlakuan dengan 5 ulangan. Perlakuan tanah tanpa pemupukan (P1); tanah dengan pupuk NPK (P2); tanah dengan kompos (P3); tanah dengan kompos dan pupuk hayati penyimpanan 0, 1, 2, 4, dan 6 bulan (P4-P8). Hasil uji menunjukkan viabilitas bakteri sedikit menurun setelah proses kering beku (freeze drying) kemudian stabil sampai penyimpanan 2 bulan. Setelah 2 bulan, viabilitas masing-masing bakteri yang terkandung dalam pupuk hayati menurun. Aplikasi pupuk hayati penyimpanan 0, 1, 2, 4, dan 6 bulan meningkatkan pertumbuhan dan produksi tanaman jagung. Namun semakin lama penyimpanan menyebabkan efektivitas pupuk hayati untuk mendukung pertumbuhan dan produksi jagung menurun. Produksi jagung menurun dari 109.36 gram pada P5menjadi 70.46 gram pada P8.

Abstract

Hasil penapisan bakteri penghasil enzim selulase terdahulu mendapatkan isolat PMP 0126 sebagai isolat yang berpotensi yang diisolasi dari limbah pengolahan agar skala UKM di Pamengpeuk, Garut. Isolat tersebut ternyata belum merupakan koloni tunggal, terdiri dari 2 isolat bakteri yaitu PMP 0126Y dan PMP 0126W. Isolat PMP 0126Y memiliki kemampuan mendegradasi selulosa yang lebih besar dibanding PMP 0126W. Tujuan dari penelitian ini adalah untuk memproduksi dan mengkarakterisasi enzim selulase dari isolat PMP 0126Y, serta mengidentifikasi isolat tersebut. Hasil penelitian menunjukkan bahwa enzim selulase diproduksi optimum pada hari ke-3 kultivasi menggunakan medium cair berisi  CMC 1%. Enzim kasar yang diperoleh dapat bekerja optimal pada suhu 30 °C dan pH 5, dapat ditingkatkan aktivitasnya dengan ion logam dalam bentuk garam CaCl2 dan ZnCl2 5 mM.. Pemurnian dengan sistem penukar anion dapat meningkatkan aktivitas enzim 15x dengan perolehan 20%. Dari hasil SDS-PAGE terlihat bahwa ada 3 selulase dengan perkiraan berat molekul 39, 30, dan 14 kDa. Enzim kasar ini memiliki kemampuan menghidrolisis limbah pengolahan agar sebaik ketika memecah substrat CMC,  yang mengindikasikan bahwa enzim dari isolat ini berpotensi sebagai kandidat agen sakarifikasi pada produksi bioetanol. Identifikasi bakteri dengan 16S-rDNA menunjukkan bahwa isolat ini memiliki kemiripan 96% dengan bakteri Chryseobacterium indologenes McR-1.

Abstract

Streptomyces sp. TTA 02 SDS 14 is a transglutaminase producing bacteria which previously had been  screened along with more than one hundred isolates. This research aimed to purify and characterize transglutaminase from this strain. Transglutaminase was purified from crude enzyme by ultrafiltration, Q-Sepharose ion exchange chromatography and Sepacryl S200 size exclusion chromatography sequentially, obtaining yield and purification fold of  1.36%  and 27 folds, respectively. The molecular weight of the purified transglutaminase was 72 kDa detected by zymogram gel electrophoresis. The optimum temperature and pH were 50°C and 6. The transglutaminase was stable at 45°C and could be activated in the presence of 5 mM and 10 mM of Na+, K+, Li+,Ca2+, Mg2+, BPB (4-bromo-phenacyl bromide), and IAA (iodo acetamide acid), but the activity was inhibited by  the presence of Cu+, Zn2+, and PMSF (phenyl methyl sulfonyl fluoride).

Abstract

Pseudomonas sp. is one of bacterial groups having ability to promote plant growth and health. Of a hundred successfully isolated Pseudomonas sp. from soybean rhyzosphere, 98 were found to produce indole acetic acid (IAA) ranging from 0.33 to 16.02 ppm. These isolates are bacilli, motile, Gram negative, and showing positive oxidase assay. One of them, i.e. Pseudomonas sp. CRB17, can promote plant growth by means of significant stimulation of primary root length and lateral root number. This isolate was then subject to mutagenesis using transposon Mini-Tn5Km1 to increase IAA production. Mutagenesis was done by conjugation between E coli S17-1 (l pir) carrying transposon mini-Tn5Km1 (donor) and Pseudomonas sp. (recipient), resulting in conjugation frequency of approximately 3.1 x 10-5 cell per recipient. The resulted CRB17 mutants were then tested for their ability to produce IAA, one of which showed an increment of IAA production up to 77.5%, while some others showed no significant change or even had a reduction to 55.3%.  Sequence analyisis of 16S rRNA gene of Pseudomonas sp. CRB17 indicated that it has a high homology with that of Pseudomonas plecoglossicida (identical value of 99%). The results recommends that mutagenesis using transposon can be applied to increase IAA production, especially in Pseudomonas sp. CRB17.

Abstract

Oil palm plantations have a good prospect in Indonesia. One of the efforts to improve the productivity of oil palm plantation is the application of bacteria as biological fertilizer. The research was conducted to characterize and apply the nitrogen-fixing and indole-3-acetic acid producing bacteria in oil palm seedlings. The bacteria was isolated from soil samples which taken from Taman Nasional Bukit Dua Belas (TNBD) Jambi. Nitrogen free bromthymol blue (NFB) is used as media for nitrogen-fixing bacterial isolation. Selected isolate named A13 had an ability to form white pellicle on the surface of the semisolid medium, increased the pH, and changed the color of medium from green to blue Isolate A13 was identified as Gram-negative bacteria and had a rods shape. Analysis of 16S rRNA gene sequence showed that isolate A13 had a similarity with Pseudochrobactrum assacharolyticum. Hypersensitivity assay on tobacco leaves showed that isolate A13 was not a pathogen. During 48 hours of incubation, isolate A13 produced a maximum of IAA at the 24th hour of incubation. Isolate A13 produced 0.675 ppm of ethylene/hour in Acetylene Reduction Assay and 69,839 ppm of IAA in HPLC methods. This was the first report on nitrogen fixation and IAA production by Pseudochrobactrum assacharolyticum and its application in the soil of oil palm seedlings. Application of isolate A13 in oil palm seedling increased significantly the number of lateral roots, stem diameter, and height of plants

Abstract

Oil palm plantations are the most invasive land use changes in Southeast Asia. It must have affected unique natural biodiversity. This study aimed to investigate the diversity of soil bacteria based on 16S rRNA gene profiles from tropical forest and oil palm plantation in Jambi Province, Indonesia. Soil sample was taken from tropical forest and oil palm plantation from Jambi province, Indonesia. The forest site is in Bukit Duabelas National Park, and the nearby oil palm plantation is in Sarolangun District, Jambi Province, Indonesia. The diversity of bacterial communities from topsoil was studied using Denaturing gradient gel electrophoresis (DGGE) of 16S rRNA gene and common biodiversity indices. PCR amplification of 16S rRNA gene was successfully conducted primers-using 33F/ 518R primers. Phylogenetic approach was used for revealing the community shift of bacterial phyla and genera in both areas. Phylogenetic analysis showed there were 4 phyla of bacteria i.e., Firmicutes, Alphaproteobacteria, Gammaproteobacteria, and Actinobacteria, respectively. Actinobacteria was the most dominant group in both areas. The composition of soil bacterial community in the oil palm plantation, based on total number of bands 16S rRNA generated from DGGE was richer than that in the Bukit Dua Belas National Park. It was probably caused by plantation year circle more than 10 years and routine activities during the plantation management, such as applications of agricultural lime, herbicide and fertilizer.

Abstract

Proteases are among the most important enzymes in both food and non-food industries taking up almost 60% of the world enzyme market. This enzyme has been used for many industrial processes, especially in the detergent industry. The purpose of this study was to characterize the protease from Bacillus licheniformis F11.1 as a bio-detergentagent. An enzyme assay of protease activity was used to assess and characterize the protease enzyme from B. licheniformis F11.1. It showed that the highest pH protease activity for alkaline protease occurred at pH 8.0 with a value of 35.00U/mL. Under incubation temperature, the protease had the highest activity at 50 °C with a value of 24.46 U/mL. Protease activity was inhibited by Ca2+,Mn2+, K+, and Na+ions at concentrations of 5 mM. Protease activity can beenhanced by these ions at concentrations of 2 mM. Protease stability can be measured from half-life. Under anincubation temperature of 50 °C, the half-life of the protease at pH 8, 9, and 10 was 108 min, 114 min, and 98 min, respectively. The assay for enzyme stability with an incubation temperature of 60 °C showed half-lives of 92 minutes, 56 minutes, and 61 minutes for pH 6, 9, and 10, respectively. This enzyme was found to be stable with the addition ofdetergent compounds such as sodium dodecyl sulfate (SDS), Triton X-100, ethylenediaminetetraacetic acid (EDTA), and hydrogen peroxide; all under low concentrations. Determination of the molecular weight using SDS-PAGE andzymogram found the molecular weight was 32.90-35.16 kDa. These results showed that the alkaline protease from B.licheniformis F11.1 can be used as a bio-detergent because of its tolerance to various detergent compounds.
