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

Lipase Production by Mutant Fungal Isolates for Transesterification ABSTRACTLipase is used amongst others in biodiesel production, namely in the transesterification reaction. Kernel B (KB) was a fungus isolated from the waste of palm kernel and seed. The fungus produced lipase that catalysed the transesterification reaction with a lower activity compared to that of AK Amano commercial lipase. The purpose of this study was to obtain mutant fungi with higher transesterification activities than the wild type (KB). The mutation process was carried out using ultraviolet (UV) light, ethyl methane sulfonate (EMS), and N-methyl-N’-nitro-N-nitrosoguanidine (NMNG) on KB fungus. The mutations using UV light produced 11 isolates, of which isolate m4.1KB1 produced a higher transesterification activity (0.172 U·mg-1) compared to the wild type. Mutant m5.7KB, which was generated from mutant m4.1KB1 treated using EMS, had its transesterification activity decreased to only 0.051 U·mg-1. Mutant m6.0,3KB2, which was resulted through NMNG treatment, experienced an increase in transesterification activity which was 91.2% higher than that of KB.Keywords: ethyl methane sulfonate, lipase, mutant fungi, N-methyl-N’-nitro-N-nitrosoguanidine, ultraviolet ABSTRAKLipase dimanfaatkan salah satunya dalam produksi biodiesel, yaitu dalam reaksi transesterifikasi.

Abstract

Enteropathogenic Escherichia coli (EPEC) causes gastrointestinal infections in human. EPEC invasion was initiated by attachment and aggressive colonization on intestinal surface. Attachment of EPEC alter the intestine mucosal cells. Despite this, the pathogenic mechanism of EPEC infectior has not been fully understood. This research hypothesizes that extracellular proteolytic enzymes is necessary for EPEC colonization. The enzyme is secreted into gastrointestinal milieu and presumably destroy mucus layer cover the gastrointestinal tract. The objective of this study was to assay EPEC extracellular protease enzyme by using mucin substrate. The activity of EPEC extracellular proteolytic enzyme on 1% mucin substrate was investigated. Non-pathogenic E. coli was used as a negative control. Positive and tentative controls were Yersinia enterocolitica and Salmonella. Ten EPEC strains were assayed, seven of them were able to degrade mucin, and the highest activity was produced by K1.1 strain. Both positive and tentative controls also showed the ability to digest 0.20% mucin. Key words: EPEC, protease, mucin, diarrhea

Abstract

Tobacco Mosaic Tobamovirus (TMV) is one of many important viruses infecting Solanaceous plants including hot pepper in Indonesia. To accomplish and improve the effectiveness of virus management, we used root-colonizing bacteria (rhizobacteria) isolated from healthy hot pepper. Eight rhizobacteria isolates were selected and their capacity in enhancing plant growth and inducing systemic resistance (ISR) against TMV in greenhouse trials were evaluated. The rhizobacteria was applied as seed treatment and soil drench. Bacterized-seedling showed a better growth vigor, fitness and a milder symptom than non-bacterized control plants. The protective effect of rhizobacteria was more pronounced after challenging inoculation by TMV, especially for plants treated by isolates I-6, I-16, and I-35. However, TMV accumulation was slightly affected by bacterial treatment. The rhizobacteria might improved ISR by increasing peroxidase enzyme activity but this depends on the species. Based on whole results, isolate I-35 was the potential plant growth promotion rhizobacteria (PGPR). The I-35 was identified as Bacillus cereus based on morphological characteristics and nucleotide sequences of 16S r-RNA. Key words: root-colonizing bacteria, TMV, ISR

Abstract

Plant growth promoting rhizobacteria (PGPR) play an important role in improvement of seed germination, root development, and water utilization by plants. These rhizobacteria can stimulate plant growth directly by producing growth hormones or indirectly by producing antifungal compounds/antibiotics to suppress phytopathogenic fungi. The objective of this research was to analyze the diversity of 22 antifungal-producing rhizobacteria of Bacillus sp. isolated from rhizosphere of soybean plant based on Amplified rDNA Restriction Analysis (ARDRA) and 16S rRNA Sequence. Restriction enzymes in ARDRA analysis, HinfI, HaeIII, and RsaI were used to digest 22 16S rDNA amplified from Bacillus sp. genomes. Based on this analysis, genetic diversity of 22 Bacillus sp. producing antifungal compounds were classified into eight different groups. Moreover, six selected isolates randomly from each ARDRA group that have strong activity to suppress fungal growth were analyzed for their 16S rDNA sequences compared with reference strains. The distributions of these isolates were genetically diverse on several species of Bacillus sp. such as B. subtilis, B. cereus, and B. fusiformis. ARDRA is a reliable technique to analyze genetic diversity of Bacillus sp. community in the rhizosphere.

Those three isolates were designated as sponge associated bacteria SAB S-12, SAB S-21, and SAB S-17. A simple casein and Sea Water Complete (SWC) double layer agar method was used to screen the bacteria against pathogenic bacteria producing protease, i.e. EPEC K.1.1, S. aureus, and P. aeruginosa. Among them, SAB S-12 isolate showed no inhibitory zone indicated. The isolate had the highest inhibitory activity against subtilisin and crude extract enzyme of pathogenic bacteria, the inhibitory activity was 91.6 and 98.9%, respectively. In addition, the SAB S-21 isolate had the highest inhibitory activity against thermolysin, it was 70.4%. The optimum pH and temperature for protease inhibition of the three isolates was at pH 7.0-8.0 and 40-50 oC respectively. Based on 16S rRNA gene sequence, the closest related with SAB S-12, SAB-17, and SAB-21 isolates was Providencia sp. (92% identity), Paracoccus sp. (86% identity), and Bacillus sp. (% identity), respectively.

Abstract

Use of Chitinolytic Bacteria as Biological Control of Colletotrichum capsici on Chili PlantsColletotrichum capsici is known as the causal agent of anthracnose disease in chili plant and may cause reduction of crop yield. Chitinolytic bacteria, namely Serratia marcescens KAHN 15.12, Bacillus thuringiensis SAHA 12.12, and BAE 36 were reported to have antagonistic activity against C. capsici. Therefore, a study was conducted to determine the potential of chitinolytic bacteria on controlling C. capsici on chili plants in greenhouse experiment. Three bacterial isolates used as biocontrol agent was formulated by using talcum as carrier materials. The methodologies consisted of characterization of bacterial isolates, formulation of biocontrol agent, viability test of bacterial isolate, efficacy of biocontrol agents in the laboratory and in the greenhouse.  Disease severity in the laboratory reached 64% when chili treated with isolate formulation of BAE 36.  In the greenhouse, BAE 36 isolate formulation and consortium formulation were able to suppress infection of C. capsici; each was indicated by disease incidence of 25% and 50%, respectively. These results indicated that chitinolytic bacterial formulations could be potencial as biocontrol agents of C. capsici.
