Abstract

The aim of this research was to compare the reduction effect of sucrose or table sugar concentration on growth characteristics of red ginger cultured in MS liquid medium. Shoots of red ginger was cultured on MS liquid medium without addition of plant growth regulators, supplemented with 5, 10, and 20 g/l of sucrose or table sugar for 8 weeks. Resulted plantlets were acclimatized in a greenhouse to investigate their growth and survival rate. Numbers of stomata, chlorophyll concentration as well as cross section of leaves from plantlets grown in vitro were compared to those of transplants grown in the greenhouse. The results showed that the use of table sugar at concentration of 20 g/l gave the best growth of red ginger. Meanwhile, the reduction of table sugar from 20 to 10 g/l reduced growth and survival rate of in vitro shoots as well as that of transplants in the greenhouse. Only few shoots formed roots when they were grown on the medium containing 5 g/l of table sugar, and transplants failed to grow in the greenhouse. It found that the chlorophyll content of in vitro plantlets was lower than those of transplants grown in the glasshouse. However, the number of stomata of the in vitro plantlets was higher than that of transplants grown in the glasshouse. There was no anatomical abnormalities found on the cross section of leaves between in vitro plantlets and transplants grown in the greenhouse. The replacement of sucrose with table sugar may reduce the production cost of plantlets.Keywords: red ginger (Zingiber officinale Rocs.), reduction of sugar, survival rate, chlorophyll, stomata.

Abstract

Tetrameles nudliflora is one of the endemic plants in Wallace region, especially in Mekongga Forest, Southeast Sulawesi, Indonesia. As part of our project in the field of natural drug discovery based on local bioresources, this study aimed to isolate secondary metabolite compounds from the ethyl acetate fractions of the leaves of T. nudiflora and evaluate their cytotoxic activities against breast carcinoma cancer lines, MCF-7. The methods used were various chromatography techniques such as vacuum column chromatography, gravitation column chromatography, thin layer chromatography, preparative thin layer chromatography, and re-crystallization using two different organic solvents. In the present study, two flavonoid compounds, kaempferol (1) and quercetin (2) were identified. The structures of 1-2 were determined using serial spectroscopic techniques, including mass spectrometry, one- and two-dimensional nuclear magnetic resonance. Moreover, using 3-(4,5-dimethylthiazol-2-yl)-2,5 diphenyl tetrazolium bromide (MTT) assay method, both compounds showed in vitro cytotoxic activity IC50 of 34.162 and 133.148 μg mL-1, respectively against MCF-7 cell lines.

Abstract

The studies of rice genes through functional genomics are greatly facilitated by the availability of the complete genome sequences, including the complete physical map of the japonica rice cv. nipponbare. Using the Ac and Ds transposon, that are capable of transposition in various heterologous plants including the monocotyledon rice,  combined with the enhancer element for generating activation taged lines, it is possible to discover and isolate functional genes involved in various important agronomical traits; such as those involved in abiotic stress tolerance (drought, high salt) and biotic stresses diseases and pests. We have developed 1,785 first (T0) generation of mutant nipponbare rice by transposons Ac/Ds insertions containing activation-tag, generated by transformation using Agrobacterium-mediated method. Currently, we have generated approximately 1,000 stable lines with transposon Ds and activation-tag insertion ready for screening. Efficient screening methods for mutant Nipponbare rice lines have been established for agronomically important mutant traits. Among the new phenotypes related to important agronomical traits observed were drought and salt tolerant or sensitive, stunted and robust growth, variable root penetration and other interesting traits such as reduced tillering, rolled leaf and thin tiller.   Keywords: rice, insertion mutant, gene discovery, drought, salinity

Abstract

Isolation, identification, and evaluation of antimicrobial activity of active compound produced by marine actinomycetes isolate A32 has been conducted. Production of active compound using isolate A32 was conducted by glucose, yeast, peptone medium. The fermentation was carried out at 30ºC for 5 days. The broth of supernatant was extracted using ethyl acetate. Purification of active compound used column chromatography and eluted stepwise with the chloroform and methanol solvent. Antimicrobial activity was monitored by the agar diffusion, and microbial test used as followed Escherichia coli ATCC 25922, Staphylococcus aureus ATCC25923, Bacillus subtilis ATCC 66923, and Candida albican BIOMCC00122. Results of isolation and purification of active compound produced by isolate A32 showed that this compound has a molecular weight of 503.1 g/mol with molecular formula C26H37N3O7. Analysis of spectrum using 1HNMR and COSY, this compound was suspected as Madumycin II. The antibacterial activity assay showed that this active compound was able to inhibit to the growth of Staphylococcus aureus ATCC25923 and Candida albican BIOMCC00122.

Abstract

Phytic acid is an antinutritional factor that forms 1–2% of most of the seeds and their co-products representing more than 60%  of their total phosphorus. Monogastric and agastric animals are unable to utilize phytate phosphorus either due to lack of or insufficient amount of phytate degrading enzymes. Phytases (myo-inositol hexakisphosphate-phosphohydrolase) are a special class of phosphatases that catalyze the hydrolysis of phytic acid in a stepwise manner to lower inositol phosphates, myo-inositol and inorganic phosphate. Phytases are found naturally in plants and microorganisms and a sizeable number of phytases have been purified and characterized from various fungi, yeasts and bacteria. The present investigation involves studies on the effect of moisture content, pH value and different media ingredients such as carbon, nitrogen, and surfactants on the production of phytase by the fungus  Aspergillus ficuum DSM 932 in solid-state fermentation (SSF) using rice bran as substrate. The production of phytase by SSF was favored, when the fungus was grown at a moisture content of 60% and pH 7.0, resulted in a phytase activity of 5.2 units/g dry substrate. There was a 20% increase in phytase yield in the presence of sucrose in SSF medium, while glucose and fructose were not effective in enhancing the phytase activity when used individually. Yeast extract was found to be a favorable nitrogen source for phytase production by SSF, which resulted in a 20% increase in phytase activity. There was no significant effect in increasing phytase production with the use of either soy peptone or tryptic  soy as nitrogen source. Approximately 30% inhibition in phytase activity was shown in the presence of the surfactant Tween-80 or Triton X-100 in the SSF. By supplementing rice bran with sucrose and yeast extract, and performing the SSF in tray bioreactors, a phytase activity of 6.76 units/g dry substrate could be obtained.Keywords:  phytase, solid-state fermentation, Aspergillus ficuum, nutritional factors, rice bran
