Abstract

Taxus sumatrana (Miquel) de Laubenfels is known as an endanger forest tree species grown at Kerinci National Park in Jambi,Indonesia. This plant was known potential on producing taxol. Taxol is a bioactive compound, could be used as antibacterial agent and recently confirmed to cure cancer cells. For the first time in 1960, Arthur Barclay found the taxol compound from Taxus sp.(pacific yew). However to isolate the bioactive compound, huge amount of tree biomass is needed. Research on endophytes microbes which are isolated from inner tissue of Taxus sp. declared that those microbes have potential on producing antioxidant agent for drug discovery. Isolation and conservation of endophytes and selecting its potential is promising the novel of finding new drug that may be effective for treating the newly developing diseases in human. Fifteen isolates of Taxus endophytes have been successfully studied on their ability on producing antioxidant. The results showed that endophytes fungus isolates TsC-17, isolated from Taxus sumatrana grown in Cibodas Botanical Gardens-LIPI, could produce extracellular bioactive compound which performed activity of suppressing free radical, is significantly better compared to intracellular bioactive compound eventhough it is not as high as in vitamin C. The activity of suppressing free radical resulted from bioactive compound of endophyte fungus isolates TsC-17 was 20% for intracellular bioactive compound, while it was 60% for extracellular bioactive compound and 90% for vitamin C.

Abstract

Zingiberaceae species Zingiber zerumbet var. aromaticum Val. usually propagated by vegetative part of the plant. Study on the proliferation of rhizome explants through in-vitro method were conducted on this species for propagation.The explants were cultured in MS (Murashige & Skoog) composition medium in normal and half strength concentration of macro elements, supplemented with micro elements and vitamins. Plant growth regulator (PGR) cytokinin (kinetin, adenine sulphate) were added in initiation stage.Benzyl adenine (BA), thidiazuron and 2,4D (dichlorophenoxy acetic acid) added in medium as treatments to induce shoot multiplication and adventitious shoot development or rooting plants.The media for induced multiple shoot and roots (plantlets) development, supplemented with PGR BA, thidiazuron, Indole butyric acid (D3A) as treatments and activated charcoal were added as antioxidant.In general, most of cultures were indicated have positively responds to PGR treatments. The ability of culture to produce multiple shoots and roots such as in medium with BAP (8 mg/1) + thidiazuron (0.1 mg/1) + IBA (1 mg/l)-indole butyric acid would give a better opportunity of rhizome explants proliferation and plantlets development of Z. zerumbet var. aromaticum.

Abstract

Physiological characters of four denitrifying bacteria (Bacillus sp. CPNS, Bacillus thuringiensis UPT1, Brevundimonas diminuta EA1 and Bacillus sp. UPSB) were studied based on the growth ability on various nitrate concentrations and the production of N2O gas. The characters of denitrifying bacteria were also evaluated through the existence of functional genes nirS and nosZ, encoding the nitrite reduction and nitrous oxide reduction enzymes which have important role on denitrification processes. The study showed that Bacillus sp. UPSB and Bacillus sp. CPNS isolates have a linear growth with the increasing concentration of KNO3. The N2O gas production of Bacillus sp. UPSB isolate was relatively high, about 70 ?/l, Bacillus sp. CPNS isolate was 25?/l, while the Bacillus thuringiensis UPT1 isolate was 5 ?/l and Brevundimonas diminuta EA1 isolate was 8 ?/l. It was also indicated that both Bacillus sp. UPSB and Bacillus sp. CPNS had high deninitrification activities. It was confirmed that all isolates were contained functional gen of nirS and nosZ.

Abstract

The giant corpse inflorescence (Amorphophallus titanum) is native to Indonesia. It is one of the flagships of The Center for Plant Conservation Bogor Botanic Gardens, Indonesian Institute of Sciences (LIPI) to raise public awareness for saving plants from extinction and caring the living environment. The blooming of the giant inflorescence attracts many visitors. Therefore, one of the research focuses of Amorphophallus titanum is how to predict the blooming-time in order to inform visitors earlier. The results of this study can be used as the basic information to predict the blooming of the inflorescences. Previous researchers had tried to predict the blooming based on firstly, the differential diagnostics of an inflorescence bud and leaf bud, and secondly, the growth pattern of the flowering bud from one individual sample only; whereas, our results suggested new findings. In this research, the prediction was examined from 2011-2012 on five individual samples planted in Bogor Botanic Gardens. We suggested that (1) the differential diagnostics of an inflorescence bud and leaf bud were not only based on the early bud shapes but also the growth rate, and (2) our results supported Lobin’s findings by providing a statistical formula for growth pattern of the flowering bud.

Abstract

This research has been conducted at the laboratory of in vitro fertilization of the University ofWisconsin, USA. These embryos may be used for improving genetic value of Indonesian cattle. Ovaries were collected from slaughterhouse in Wisconsin. Oocytes were matured in TCM-199 medium enriched with FSH 10 \i\lm\, estradiol 17 P lul/ml and 10 % FCS for 20 hours. The oocytes were fertilized in vitro with motile sperm selected and capacitated by using the percoll gradient with 2 ml vs 0.5 ml per layer as treatment A and B respectively. Sperm and oocytes were incubated in fertilization medium (mTALP) for 20 hours. All zygotes were cultured in CRlaa medium up to btastocyst stage and were fed with serum 5 \iV 50 )j.l in culture medium on day 6. Percentages of cleavage, morula, blastocyst, expanded blastocyst, unfertilized and degenerated ova in this study were 86.3 vs 91.6 %, 53.3 % vs 75.9 %; 32.6 % vs 63.4 %; 21.1 % vs 33.0 %; 13.7 % vs 8.4 %, 32.9% vs 15.6 % for treatment A (n=1007) vs B (n=1055), respectively. Based on result of this study, it is concluded that the best method for IVP (in vitro production) of cattle embryos is using percoll gradient with 500 ul per layer.

Abstract

N. WULIJARNI - SOETJIPTO, 1985. Effect of desiccation and storage temperature on the viability of seeds of Citrus amblycarpa. Berita Biologi 3 (3): 95- 100. Seeds of Citrus amblycarpa (Hassk.) Ochse were dried using several methods. The seeds remained fully viable when the moisture content were reduced to around 5%. Upon storage, those seeds stored at 28°, 10° and 4°C were still viable after 287 days. Further observation showed that storage at 10°, 4° and - 10°C enabled seeds to maintain their germination until the end of the experiment, i.e. 910 days. Therefore, it is concluded that C.amblycarpa seeds tend to follow the behaviour of the orthodox seeds.
