Abstract

The use of cassava (Manihot esculenta Crantz) peel for enzyme production has not been widely used. The purpose of this study was to produce complex amylase enzymes from cassava peel by A. awamori KT-11 and apply them in the manufacture of natural sweeteners. Enzyme production is carried out on red and white cassava peel. Media of cassava peel sterilized, inoculated with 1%  A. awamori KT-11, incubated for 5 days, then dried at 50°C and mashed. Making sugar is done on cassava flour, sweet potato ( Ipomoea batatas L), taro (Colocasia esculenta) and cocoyam (Xanthosoma sagittifolium) with different concentrations of 10%, 15%, 20%, and 15% and 20% enzyme concentrations. The hydrolysis process is carried out for 3 days at 60°C. The enzyme activity in red cassava peel was 405,006 U/mL and white cassava peel was 321,239 U/ml. The sugar produced in cassava, taro, sweet potato, and Cocoyam was 101.38 mg/mL, 81.18 mg/mL, 55.929 mg/mL, and 42.874 mg/mL, respectively. The results of TLC showed that cassava and taro sugar  contain maltose, lactose and glucose, sweet potatoes contained glucose and dextrin and Cocoyam containing fructose. The sweetness level of sugar from cassava, taro, sweet potato and Cocoyam is 14 brix, 12 brix, 9 brix and 9 brix, respectively.

Abstract

Vinyl acetate is a toxic substance, but has a high commercial value. In this study we show that vinyl acetate is subject to microbial degradation at rates of up to 6.38 and 1 mmol/h per g (dry weight) under aerobic and anaerobic conditions, respectively. It was hydrolyzed by bacterium V2 to ethano, acetaldehyde and acetate. The enzymes involved in the metabolism of vinylacetate were vinyl acetate esterase, aldehyde dehydrogenase, and alcohol dehydrogenase, which localized in the cytoplasmic fraction. The Km values of vinyl acetate esterase and alcohol dehydrogenase were 6.13 mM and 0.24 mM. respectively. Vinyl acetate esterase hydrolyzed the ester to acetate and vinyl alcohol. The Latter isomerized spontaneously to acetaldehyde and was then converted to acetate.The acetaldehyde was disproportionated into ethanol and acetate. The acetate was then converted to acetyl coenzyme A and oxidized through the tricarboxylic acid cycle and the glyoxylate bypass .

Abstract

   The sustainability and increasing the national rice production require the readiness of food and agriculture sector cope with the impacts of climate change, land degradation, drought area, sloping production and the raising of population growth. Adaptation plays an important role in ensuring the sustainability of food security. This research aimed to develop drought-tolerant variety of Inpari 30 (submergence tolerance variety) and Situ Bagendit through marker-assisted backcrossing-through pyramiding gene of identified QTLs for foreground selection and to explore SSRs and 6K SNPs for background selection distributed in 12 rice chromosome of drought tolerant donor (Cabacu) and recipient rice (Inpari 30 and Situ Bagendit). The foreground selection revealed that flanking SSRs of each QTLs (qRPF2.1, qGPP2.1, qSPP4.1 and Sub1) was less than 2 cM. The background selection through polymorphic survey of Rice 6K SNP primers revealed 2457 (53,3%) polymorphic SNPs on Inpari 30 vs Cabacu and 2563 (55,6%) polymorphic SNPs on Situ Bagendit vs Cabacu with the average distance about 0.74 cM/chromosome. The genotypic selection of F1 Inpari 30/Cabacu and F1 Situ Bagendit/Cabacu have already in heterozygote condition for these 4 QTLs target. These lines was continued for backcross breeding to develop BC1F1 Inpari 30/Cabacu and BC1F1 Situ Bagendit/Cabacu generation.

Abstract

Exploitation on plant population may put the endemic plants into an endangered state, hence, these plants will need to be conserved. In order to pursue conservation on endemic plants, we conducted in vitro seed germination and shoot multiplication of seven alpine and sub-alpine species endemic to Mount (Mt.) Jaya, in Papua, Indonesia, i.e. Tetramolopium klossii, Deschampsia klossii, Papuacalia cartenszensis, Epilobium hooglandii, Gaultheria novoguinensis, Rhododendron correoides and Rhododendron culminicolum. These species are categorized as slow-growth plants found in higher altitude (over 3700 m above sea level) and low temperature of Mt. Jaya. Seeds were surface-sterilized using Na-hypochloride and germinated aseptically on Murashige and Skoog (MS) medium. Dytikinin benzyl adenine (BA) was used for shoot multiplication. Seedling cultures were maintained in a controlled environment with  continuous low light intensity (800 lux) and at temperature 26-27oC. Results showed that most species had more than 80% of germination rate on MS medium after a week in culture. BA was required to enhance shoots multiplication. Woody Plant (WP) (Lloyd & McCown, 1981) medium gave better shoot multiplication for R. culminicolum.

Abstract

In order to utilization of cassava peel waste this study tries to produce glucoamylase by solid state fermentation with Aspergillus awamori KT-11. Composition medium and drying technique are affecting the glucoamylase production. The highest glucoamylase activities were from cassava peel plus mineral medium. Activity glucomaylase in cassava peel plus mineral medium by oven drying was 365 U/mL and freeze dring was 452 U/mL.  It is conclud cassava peel plus mineral is a better substrate for glucoamylase production from A. awamori KT-11 in solid state fermentation. Powder of glucoamylase also proved capable of hydrolyzing starch-based biomass.

Abstract

Alkanes is a major component of crude oil that can be hydrolized by enzyme alkane monooxygenase from bacteria. Nine oil-degrading bacteria were analyzed their capability to degrade alkanes (pristane and paraffin). The result of growth test on paraffin and pristane were showed that 9 isolates could be devided into two groups. First group (BL09, BL31 and BL45) could degrade both paraffin and pristane, and second group (BL01, BL06, BL44, BL057, BL058 and BL071) preferred to degrade paraffin than pristane. Three isolates (BL09, BL31 and BL45) have activity to decrease paraffin and pristane until less 50% remain. Based on homology analysis of 16S rRNA gene sequences showed that isolates No. BL09, BL31 and BL45 were identified as Alcanivorax sp. and the partial sequences of the alkB gene from those three isolates are showing 66-68% of identity compare with some mono-oxygenase gen from database of genbank.Keywords: biodegradation, alkane, monooxygenase, cloning, alkB
