Abstract

β-Glucan is one of the most abundant polysaccharides in yeast Saccharomyces cerevisiae cell wall. The aim of this research is to explore an alternative nitrogen sources for β-glucan production. S. cerevisiae were grown in fermentation medium with different nitrogen sources. Peptone 2%, glutamic acid 0,5%, urea 0,2%, and diammonium hydrogen phosphate (DAHP) 0,02% were used for nitrogen source in the medium. A two liter air-lift fermentor was used in the fermentation process for 84 hours (T = 300C, pH 7, and 1.5 vvm for the aeration). During the fermentation, optical density, extraction of β-glucan, glucose and protein in hydrolisate cultured were determined. β-glucan production level is similar with the growth rate of yeast and followed by decreasing glucose and protein content in hydrolysis cultured. The highest and lowest β-glucan content were obtained from peptone (933.33 mg/L) and glutamic acid (633.33 mg/L) as a nitrogen source in cells cultured after fermentation completed respectively. Yeast cells cultured with urea and DAHP as a nitrogen source give the same content of β-glucan about 733.33 mg/L. β-glucan concentration produced in medium with urea was a higher than that produced usingglutamic acid and DAHP as a nitrogen source. The result indicated that urea can be used as an alternative nitrogen source for theproduction of β-glucan. Urea is easily available and cheaper than peptone, glutamic acid and DAHP.© 2007 Jurusan Biologi FMIPA UNS SurakartaKey words: β-glucan, Saccharomyces cerevisiae, air-lift fermentor

Abstract

The detail observation had been done on the morphological characters of Rafflesia hasseltii from Bukit Tiga Puluh National Park (BTNP). Currently, this endangered and rare flower found in two populations in this park, Aek Telap and Mandi Urau, Tanah Datar. The preliminary study on morphological characters of flowers from this site shows blotches and dot pattern variability. The detail observation of morphology of R. hasseltii from BTNP, presented the similarity to its type except the blotches pattern in perigone lobe. However, the further monitoring research is still needed to observe more flowers in this site. Due to its rarity, study on all Rafflesia species must be carefully done especially in using the characters of blotch for taxonomy evidence, as this characters show the variability among the flowers within population.© 2007 Jurusan Biologi FMIPA UNS SurakartaKey words: Rafflesia hasseltii, tjendawan muka rimau, morphology

Abstract

The most serious impact after exploiting coal by opened peat mining is acid mine drainage phenomenon. This is an oxidation of sulphide minerals by releasing sulphate that generate the environment acidity. This study was aimed to observe the ability of sulphate reducing bacteria (SRB) isolated of sludge paper mills in decreasing the ex-coal mining sulphate content. Before inoculating onto the soil, SRB was incubated in the sterilized organic matter for 4 days. Organic matter inhabited SRB mix with ex-coal mining soil (1:3 v/v). As a control was a series ex-coal mining mixed with non inoculated organic matter (1:3 v/v). The experiment is carried out in randomized complete design in 3 replications, each consist of 5 buckets. All buckets were maintained in saturated water content. Every 5 days for 20 days the sulphate content, pH and Eh were assessed to observe the bioremediation progress. The result shown that SRB was able to reduce 84.25% excoal mining sulphate content in 20 days. In consequence, the soil pH was increased from 4.15 to 6.66 during the process. It is recommended that SRB is prospective to be further developed as a sulphate bioremediation agents on ex-coal mining soil.© 2007 Jurusan Biologi FMIPA UNS SurakartaKey words: bioremediation, ex-coal mining, sulphate reducing bacteria

Abstract

Analysis of the variation of D-Loop mtDNA of East Kalimantan orangutan was done to provided the genetic information data from endangerd species in order to support their population conservation efforts. The reason using mtDNA in this research is caused by higher level of mutation ( 5 – 10 trimes) when compared with nuclear DNA and it enable to transmited via maternal transmission without experience in recombination. From the analysis conducted on 38 samples resulting eight types of haplotype that is A, B, C, D, E, G, H and I haplotype. Level of variation of the haplotype at East Kutai district was more uniform when compared by variation in Kutai district. From the paternal analysis had been got three cluster with the nearer among cluster IADG and cluster EH compared by cluster BC. Dissociation timebetween haplotype are 250.000-400.000 years ago, and known the population of East Kalimantan orangutan separated from Sumatran orangutan (X97708) since 1.158.300 years ago.© 2007 Jurusan Biologi FMIPA UNS SurakartaKey words: , D-Loop mtDNA, East Kalimantan

Abstract

A research about nitrogen–use efficiency (NUE) and trees identification was conducted at different vegetation type at Cikaniki, Halimun- Salak National Park, West Java. Plot quadrate methods (20 x 50 m) was used to analyze trees vegetation and Kjeldahl methods was used to analyze leaf nitrogen. The width and length of the leaf was also measured to obtain the leaf surface area. The result showed that there are 61 individual trees which consisted of 24 species was identified. The species which have 5 highest important value are Altingia excelsa (64,657), Castanopsis javanica (39,698), Platea latifolia (27,684), Garcinia rostrata (21,151), and Schima walichii (16,049). FuthermoreEugenia lineata (13,967), Melanochyla caesa (12,241), Quercus lineata (10,766), platea excelsa (10,766) have lower important value. Other trees have important value less than 10. Morphological and nitrogen content analyze were done on 4 species : Quercus lineata, G. rostrata, A. excelsa, and E. lineata. Among them, Quercus lineata has highest specific leaf area (SLA) (0,01153), followed by G. rostrata (0,00821), A. excelsa (0,00579), and E. lineata (0,00984 g/cm2. The highest number of stomata was found on A. excelsa (85,10/mm2), followed by E. lineata (74,40/mm2), Q. lineata (53,70/mm2), and G. rostrata (18,4 /mm2). The emergent species (A. excelsa and Q. lineata)have higher nitrogen content than the underlayer species (G. rostrata and E. lineata). A. excelsa have highest nitrogen use efficiency (28,19%) compare to E. lineata (23,81%) , Q. lineata (19,09%), and G. rostrata (14,87%). Although not significant, emergen species have higher NUE than underlayer species.© 2007 Jurusan Biologi FMIPA UNS SurakartaKey words: nitrogen-use efficiency, vegetation type, plants, West Java
