Abstract

Basal stem rot caused by Ganoderma boninense is the most serious disease of oil palm (Elaeis guineensis) in Indonesia and it has caused major loss in palm oil production. Mycorrhizosphere bacteria offer possible advantages as biocontrol agents as they live and proliferate together with arbuscular mycorrhizal fungi, which have an ability to increase plant resistance against pathogens. A study was conducted to isolate mycorrhizosphere bacteria from spores of arbuscular mycorrhizal fungi and test their antagonistic effects against G. boninense in vitro. All bacterial isolates were identified based on 16S rDNA analysis and it revealed that eleven out of twenty mycorrhizosphere bacteria isolated were related to Bacillus with similarity ranging from 97 to 100%, whereas other isolates were identified as Pseudomonas, Streptomyces, Kocuria, Enterobacter, Brevundimonas, and Alcaligenes with similarities ranging from 96 to 100%. Fourteen out of twenty mycorrhizosphere bacteria showed a varying degree of inhibition towards the growth of G. boninense in vitro. Of these, isolate B10 (closely related to Bacillus subtilis ZJ06) showed the highest inhibitory effect followed by B17 (closely related to Bacillus subtilis N43). Therefore, these bacteria have a potential to be used as biocontrol agents to control basal stem rot disease caused by G. boninense in oil palm.

Abstract

Annonaceous acetogenin was extracted from Annona squamosa (Srikaya) seeds. It has cytotoxic activity against cancer cells and lower toxicity compared to other cancer drugs. Endophyte from Annonaceae is expected to have similar extracted metabolites to the host, thus increasing the economic value. This research is a preliminary study to obtain active compounds with potential as anti-cancer agents from endophytic fungi of Srikaya plants. Four endophytic fungal strains were isolated from Srikaya plants (Annona squamosa) and identified based on 28S rDNA sequence. The isolates are SKY II.3.1, SKY I.1.2, SKY II.3.2, and SKY III.3.1, and have similarity with Fusarium sp Vega760, Fusarium sp NRRL 22354 NRRL223, Nectria rigidiuscula, and Fusarium sp BOL35, respectively. The identified isolates were fermented in liquid media for three weeks. The liquid and mycelium were extracted using ethyl acetate. Whole extract of each fermented isolate was partitioned and evaporated to obtain ethyl acetate extract. Cytotoxicity assay of ethyl acetate extract was carried out at level 100 ppm by Methyl Thyazole Tetrazolium (MTT) viability test towards MCF-7 (breast cancer cell). The result indicated that each ethyl acetate extract could inhibit the viability of cell MCF-7 with 11.34, 99.78, 91.48, and 96.84%, for SKY II.3.1, SKY I.1.2, SKY II.3.2, and SKY III.3.1, respectively. Based on the results of cytotoxicity assay on MCF-7 breast cancer cells, endophytic fungi isolates SKY I.1.2, SKY II.3.2, and SKY III.3.1 are potential as sources of anti-breast cancer compounds.

Abstract

Hydroxyoctadecadienoic acid (HODE) is one of hydroxy fatty acids that has anticancer activity.  HODE was previously produced by chemical synthesis or bioconversion from linoleic acid. This is the first paper reported production of HODE by Curvularia lunata an endophytic fungi of Cibotium barometz. Various carbon and hydrogen sources have been tested for their effects on the production of  HODE by C. lunata. Glucose, lactose, maltose, xylose, and sucrose were used as carbon sources, while yeast extract, monosodium glutamate, urea, and NH4Cl were used as nitrogen sources. Fermentation was done using 100 ml medium in 250 ml Erlenmeyer flask at 150 rpm, 28 oC for 10 days.  HODE products were analyzed by high pressure liquid chromatography using C18 coloumn and eluted by gradient system of acetonitril-water from 15% to 100%. Glucose  and monosodium glutamate were found to be the best carbon and nitrogen source.  The optimum concentration of glucose and monosodium glutamate for the production of HODE were 10 mg L-1 and 12 mg L-1 respectively.

Abstract

The effects of mycorrhizal endosymbiotic bacteria Bacillus subtilis B10 and composite of arbuscular mycorrhizal fungal spores in green house experiment were examined in order to evaluate their effectiveness and compatibility with oil palm seedlings in the presence of a fungal pathogen Ganoderma boninense, the most serious pathogen in oil palm (Elaeis guineensis Jacq) in Indonesia. A three factors experiment were conducted, with mycorrhizal inoculation (M0 and M1), bacterial B. subtilis B10 inoculation (B0 and B1), and G. boninense inoculation (G0 and G1) as the first, second, and third factors, respectively. The results showed that disease severity index, plant height, root dry-weight, and phosphorus uptake were affected by co-inoculation of mycorrhizal endosymbiotic bacteria B. subtilis B10 and composite of arbuscular mycorrhizal fungi. Co-inoculation of mycorrhizal endosymbiotic bacteria B. subtilis B10 and arbuscular mycorrhizal fungi did not only reduce the percentage of basal stem rot incidence, but also significantly increased plant height and phosphorus uptake by oil palm seedlings. Our results suggest that in oil palm seedlings mycorrhizal endosymbiotic bacteria B. subtilis B10 worked synergistically with arbuscular mycorrhizal fungi in increasing plant adaptation toward biotic stress of pathogen G. boninese and could be promising biocontrol agents.

Abstract

Surfactin is a lipopeptide biosurfactant that show potential biomedical application due to its activities such as antiviral, antibacterial, antifungi, anticancer, and antimycoplasma. Bacillus amyloliquefaciens MD4-12, isolated from oil-contaminated soil, produced promising yield of surfactin in McKeen medium. The production of surfactin was influenced by many fermentation process parameters such as carbon, nitrogen, minerals and also environmental conditions such as pH and agitation. Therefore, to obtain high yield of surfactin by Bacillus amyloliquefaciens MD4-12, optimization of process production was conducted in shake flask fermentation using response surface methodology. McKeen medium composition was used as basal medium.  Screening of the best carbon and nitrogen source were selected in preliminary experiments followed by selection of the influencing significant parameters on surfactin production using Plackett-Burman design. Selected parameters were optimized by central composite design and for the data analysis was used response surface methodology. The result showed that the optimum medium composition contained (g/L) 45.0 glucose, 6.33 urea, 1.0 monosodium glutamate, 1.85 MgSO4.7H2O, 0.4 KCl, 0.5 K2HPO4 and 0.5 mL trace elements. The surfactin yield at optimal condition was 1.25 g/L, increased 2.4 times compared to condition prior to optimization.
