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.

Inasua is a traditionally product of wet salt fish fermentation produced by Teon, Nila and Serua (TNS) Communities in Central Maluku, Indonesia. The community made this fermented fish to anticipate the lean time when fisherman could not go to sea. The fish that used as inasua raw material is demersal fishes that live around coral reefs, such as Samandar fish (Siganatus guttatus), Gala-gala fish (Lutjanus sp.) and Sikuda fish (Lethrinus ornatus). The objective of the research was to isolate and characterize of bacterial indigenous in Inasua from three producers in Seram Island. The measurement of pH from inasua samples were 5.9, 5.0 and 5.8, respectively. The highest number of lactic acid bacteria was found from Gala – gala inasua was 2,5x107 cfu/g sample. Isolation of all isolates bacteria from inasua showed that a total of 7 isolates of bacteria was obtained from Samadar inasua, 9 isolates from Gala-gala inasua, and 7 isolates from Sikuda inasua. From a total of 23 isolates, only 6 isolates had characteristic as lactic acid bacteria that were Gram positive, negative catalase, and cocci shape. The microscopic characteristics of the isolates are coccid in pairs or uniforms which combine to form tetrads. Carbohydrate utilization test of selected isolate by using API 50 CHB kit indicated that 13 carbohydrates are fermented by these isolates after incubation for 48 hours. The research was concluded that the dominant bacteria in inasua sample is cocci-lactic acid bacteria.Keywords : fermented fish, inasua, lactic acid bacteria, MRSA medium

Protease of two Streptomyces sp. strain were chosen for characterization because of the large clear zone surrounding the colony in nutrient agar media containing 1% (w/v) skim milk. Extracellular protease from the two isolates SLW 8-1 and 45I-3 were characterized following incubation of the isolate in Nutrient Broth media containing skim milk or chicken feather (1%). The optimum activity of the protease SLW 8-1 was at pH 9 and 80 ºC, whereas that of the keratinase was at pH 6.5 and 70 +C. Protease of strain 45I-3 showed its optimum activity at pH 7.5 and 50 ºC whereas the keratinase was at pH 8.5 and 80 ºC.

Genetic Diversity of Plant Growth Promoting Rhizobacteria of Bacillus sp. Based on 16S rRNA Sequence and Amplified rDNA Restriction Analysis SYAMSUL BAHRI SYAMSUL BAHRI; ARIS TRI WAHYUDI; NISA RACHMANIA MUBARIK

Plant-growth promoting rhizobacteria (PGPR) are rhizosphere associated soil-borne bacteria that can enhance plant growth and inhibit the development of root pathogens. Many soil bacteria have been used as PGPR, and one of them is Bacillus sp. The implementation of PGPR is constrained by genotype fluctuation that makes it inactive on the rhizosphere. Our previous study had characterized and revealed that 11 Bacillus sp. isolated from the soybean plant rhizosphere were PGPR. To asses and compare the genetic diversity of these isolates, Amplified Ribosomal DNA Restriction Analysis (ARDRA) and DNA sequence analysis of 16S rRNA were conducted. The construction of Neighbor-joining trees and bootstrap analysis of 100 resamples of ARDRA and 16S rRNA gene sequences were performed using Treecon software for windows ver. 1.3b. ARDRA analysis was done by using four restriction enzymes (RsaI, HaeIII, CfrI and HinfI), resulting in four phylotypes, respectively phylotype I (Bacillus sp. Cr24, Cr33, Cr64 and Cr68), phylotype II (Bacillus sp. Cr 31 and Cr66), phylotype III (Bacillus sp. Cr44 and Cr71) and phylotype IV (Bacillus sp. Cr67, Cr28 and Cr69). Results of BLASTN from 16S rRNA gene sequences showed that these isolates are genetically diversed. The evolution relationship of Bacillus sp. could be shown by the 16S rRNA gene sequences analysis, while ARDRA based on the digestion sites showed their variability.

Bacillus sp. AQ-1 was isolated from household aquarium sediment. The isolate produced extracellular xylanolytic enzymes on xylan containing agar medium. Based on morphological, and physiological analysis, the isolate was identified as Bacillus sp. AQ1. The effect of temperature and pH on isolate growth and xylanase production were observed. The best condition observed for the enzyme production in Luria Broth supplemented with 0.5% oat spelt xylan medium was at 40 °C pH 7. The maximum enzyme production was 0.23 U mL-1 after 20 h of fermentation. Two different medium compositions (A and B) were examined for xylanase production. The maximum growth of the isolate and the xylanase production was better in A medium. Replacing oat spelt xylan in medium A with fruitless oil palm bunch in the medium caused the growth slightly slower than that of in the original formula. However, the xylanase production was 3 times higher in fruitless oil palm bunch medium. Optimum activity of the crude enzyme was observed at 60 °C and pH 7. Each ml of the crude enzyme contained 55.21 U xylanase, 8.12 U amylase and 0.50 U carboxymethylcellulase

Accumulation of feed excess in commercial shrimp ponds due to overfeeding could decrease water quality. Protein and starch are the primary components of shrimp feed. This study was conducted to characterize extracellular proteases and amylases of Bacillus spp. isolated from shrimp ponds. 72 proteolytic and amylolytic Bacillus spp. isolates were screened from shrimp ponds in Karawang, West Java. Ten isolates were selected for further characterization for their growth and ability to reduce total suspended solid generated from commercial shrimp feed. Bacillus sp. DA 5.2.3 and L5 showed excellent activity in reducing total suspended solid, by 37 and 30% respectively. Protease and a-amylase activities of Bacillus sp. DA 5.2.3 isolate were consistently higher than that of L5. Maximum total and specific protease activity of DA 5.2.3 isolate was 2.0 U mL-1 and 40.9 U mg-1 respectively, while the activities of the L5 isolate were 2.1 U mL-1 and 23.0 U mg-1 respectively. Based on its 16S rRNA gene sequences, Bacillus sp. DA 5.2.3 showed 99% similarity to Bacillus cereus XHJ-2-6. Bacillus sp. DA 5.2.3 could potentially be applied to maintain water quality by reducing total suspended solid in water columns of shrimp ponds.

Kedelai (Glycine max) merupakan salah satu tanaman pangan yang dibudidayakan. Kebutuhan kedelai yang selalu meningkat setiap tahun mendorong usaha peningkatan terhadap produksi kedelai. Upaya peningkatan produksi dapat dilakukan dengan menggunakan pupuk hayati dan memanfaatkan lahan yang kurang produktif di Indonesia. Pupuk hayati yang digunakan mengandung isolat Bradyrhizobium japonicum sebagai penambat nitrogen dan Aeromonas salmonicida sebagai pelarut fosfat. Isolat yang terdapat dalam pupuk hayati diharapkan dapat membantu pertumbuhan kedelai di tanah asam dengan menyediakan unsur nitrogen dan fosfat. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian pupuk hayati yang terdiri atas B. japonicum (BJ 11 wt) dan A. salmonicida pada penanaman kedelai di tanah asam. Tanaman percobaan dibuat dalam empat kelompok, yaitu dengan inokulasi Isolat BJ 11 (wt), PP, BJ 11 ditambah dengan PP, dan tanpa inokulasi (kontrol). Hasil penelitian menunjukkan bahwa aplikasi B. japonicum dan A. salmonicida cenderung dapat meningkatkan laju pertumbuhan tanaman, jumlah daun, dan bobot kering akar. Kata Kunci: Bradyrhizobium japonicum, Aeromonas salmonicid, Tanah Masam dan Kedelai Soybean (Glycine max) is one of cultivated food crops. Since the need of soybean is always increased every year, it needs some efforts to improve soybean production. One of the steps can be done is by using biofertilizer in a less productive land such as acid soil. Biofertilizer that used in this study consist of Bradyrhizobium japonicum as nitrogen fixation and Aeromonas salmonicida as phosphate solubilizer bacteria (PP). Isolates contained in the biological fertilizer is expected to help the growth of soybean in acid soils by providing elements of nitrogen and phosphate. The aim of this research was to know the effect of using biofertilizer consisted of B. japonicum (BJ 11 wt) and A. salmonicida (PP) to soybean growth in acid soils. The experiment was arranged with four group treatments that were inoculation with BJ 11 (wt), PP, BJ 11 plus PP, and without inoculation (as control). The results showed that the application of B. japonicum and A. salmonicida as inoculant mixture tend to increase plant growth, leaf number, and dry root weight. Keywords: Bradyrhizobium japonicum, Aeromonas salmonicid, Acid Soil and Soybean
