Abstract

The objective of this research was to know the antibacterial activity from the Porphyridium cruentum. P. cruentum is the Rhodophyceae algae. The extraction of microalgae biomass used dichloromethane solution and resulted three types extracts. Antibacterial activity of the extracts using the clear zone method to Escherichia coli, Bacillus subtilis and Staphylococcus aureus bacteria. Identification of antibacterial substance of the extracts were using Gas Chromatograph Mass Spectrophotometer (GCMS). The results showed that C type extract have antibacterial activity to all of indicator bacteria, neither do A type extract. Whereas the B type extract inhibited to B. subtilis and S. aureus growth. Analysis of the antibacterial compound by GC-MS was fatty acid. The major component of antibacterial from the P. cruentum was metil hexadecanoate acid (palmitic acid), the percent area was 41,15 % of B type extract and 60,36 % of C type extract.© 2007 Jurusan Biologi FMIPA UNS SurakartaKey words : Porphyridium cruentum, dichlorometane extract, antibacterial activity, GCMS

Abstract

An observation on flowering behaviour of 20 selected taro (Colocasia esculenta (L.) Schott.) cultivars was conducted at the Germ Plasm Conservation Garden belonging to the Reserch Centre for Biotechnology of the Indonesian Institute of Sciences (LIPI), Cibinong, Bogor Regency. The observation included the emergence of inflorescences, the number of inflorescences in a cluster, the opening of the inflorescence, maturity of pistilate and staminate flowers, and pollinating agents that might play role in the pollination process. The study was aimed at elucidating some baseline information that might be used as a base to carry out breeding programme for future cultivarimprovement. The study indicated that the 20 cultivar studied may be divided into 3 cultivar groups, namely a) Cultivars which fully did not appear to flower during the periode of obeservation, which includes Lampung, Enau, Siriwa, Ketan and Bentul biru, b) Cultivars that produced only a few (not more than 3) inflorescences per cluster or per individul plant. This includes cultivars : Bogor, Bentul, Kaliurang and Ketan hitam and c) Cultivars that were profusedly flowering (produced a lot of inflorescences), usually 4-5 inflorescences per cluster and several clusters in an individual plant. This includes cultivars : Sutera, Semir, Lampung hitam, Boring, Burkok, Berod, Lampung hitam, Lompong, Ketune dan Kudo. The cultivar Sutera produced flower quite readily, followed by Burkok. Apart from the few inflorescences it produced, the cultivar Kaliurang also produced rather abnormal shape of inflorescence with only a few pollen grains. Taro flowers proved to be protogenic since the atipulate flowers have become receptive 1-2 days prior to anther dehiscence. Pollination was due to the role of (Dacus dorsalis).© 2007 Jurusan Biologi FMIPA UNS SurakartaKey words: Colocasia esculenta, talas, inflorescences, floweringpendahuluan

Abstract

Sungkai or jati sebrang (Peronema canescens Jack) is one of the industrial timber estate species native to Indonesia, which is commonly chosen for reforestation and as raw materials for the furniture and handicraft industry. In order to provide this planting material in large and sustainable quantities, a technique for in vitro propagation of sungkai through adventitious shoot proliferation is needed and has been successfully developed at the Research Centre for Biotechnology, LIPI. Since tissue culture method is prone to genetic variations, it is important to assess the genetic uniformity of sungkai planting materials derived from this in vitro method at an early stage. In this research, early detection of genetic uniformity was done by morphological observation of the regenerant plants and RAPD analysis using 4 primers namely OPB 5, OPB 9, OPH 11 and OPH 19. Morphological test showed differences in leaf shape, stem diameter and plant height among plantlets originating from Kalbar, Kaltim, Jambi and Cibinong. However, RAPD analysis with PCR showed that all planting materials were genetically uniform among those originating from the same or different places.© 2007 Jurusan Biologi FMIPA UNS SurakartaKey words: sungkai (Peronema canescens Jack), perbanyakan in vitro, morfologi, RAPD

Abstract

Speciation or formation of new species is a process which may take very long time. When a new species is really formed from a previous species is still unknown exactly. However, sometimes when populations no longer interbreed, they are thought to be separate species. As natural selection, if populations adapt the occupying different environments, they will diverge into races, subspecies, and finally separate species. There are some models of speciation such as geographical, polyploidy, chromosomal, and ecological speciation. However, in the myrtle family (Myrtaceae) they can be grouped into two big models of speciation namely the rapid and slow speciation. This review points out that hybridization is a major factor affecting Myrtaceae, although evolution activities were also approved by the fact that some fossil pollens have been found in Antartica© 2007 Jurusan Biologi FMIPA UNS SurakartaKey words:.speciation models, mutation, evolution, Myrtaceae

Abstract

Lignin is a phenylpropanoid polymers with only few carbon bonds might be hydrolized. Due to its complexity, lignin is particularly difficult to decompose. Ganoderma is one of white rot fungi capable of lignin degradation. The ligninolytic of several species Ganoderma growing under different carbon sources was studied under controlled conditions which P. chrysosporium was used as standard comparison. Three types of ligninolytic, namely LiP, MnP, and laccase were assessed quantitatively and qualitatively. Ratio between clear zone and diameter of fungal colony was used for measuring specific activity qualitatively. Four sspecies of Ganoderma showed positive ligninolytic qualitatively that G. lucidum KT2-32 gave the highest ligninolytic. Activity of LiP and MnP in different carbon sources was consistently resulted by G. lucidum KT2-32, while the highest activity of laccase was shown by G. ochrolaccatum SA2-14. Medium of Indulin AT affected production of protein extracellular and induced ligninolytic. Glucose, BMC, and pine sawdust did not affect the activity of ligninolytic. The specific activity of Ganoderma species was found to be higher than the one of P. chrysosporium.© 2006 Jurusan Biologi FMIPA UNS SurakartaKey words: ligninolytic, Ganoderma, carbon sources

Abstract

A research for biosurfactant production by mix culture bacteria which used hydrocarbon has been done. The isolates were selected for the highest biosurfactant production in SMSS (Stone Mineral Salt Solution) media suplemented with 0,1 % yeast extract b/v and 1 % v/v liquid paraffin by measuring the surface tension decrease. The selected isolate was then used for determination the best inoculum concentration and the carbon source as well for the highest biosurfactant production. Inoculum concentration variation were 5%, 10%, and 15% v/v (106 cells/mL) while the carbon source were glucose, liquid paraffin, hexadecane, and crude oil as the concentration of1%. The decrease in surface tension was measured as parameter which corelated to biosurfactant production. The mix culture concentration of 10% was the best and decrease surface tension 6,27 dyne/cm. The inoculum concentration of 5% (v/v) and 15% (v/v) decrease surface tension 4,08 dyne/cm and 6,65 dyne/cm respectively. The best carbon source was liquid paraffin which decrease surface tension 8,34 dyne/cm while glucose, hexadecane, and crude oil were 2,81 dyne/cm; 2,46 dyne/cm; and 4,18 dyne/cm respectively. The conclusion of this research was that bacteria showed the highest biosurfactant production at the concentration of 10% and liquid paraffin as the best carbon source.© 2006 Jurusan Biologi FMIPA UNS SurakartaKey words: inoculum, biosurfactan, surface tension.
