Abstract

One of the scientists,whose name is still inherently kept in scientists' mind nowadays, is Carolus Linnaeus. He is known as the Father of Taxonomy who has laid down the principles of taxonomy. His contributions to this discipline were inevitably giving new paradigm. Commemorating his such great and invaluable contributions on science today after 300 years, a reflection for tracking his journey, history of life and contributions to science - especially in Indonesia, is presented in this paper.

Abstract

Phytoremediation is defined as a clean up of pollutants primarily mediated by pliotosynthetic plants so its could be used as an alternative technique to overcome contaminated soil and water such an mining ecosystems. These plants have several beneficial characteristics; they have ability to accumulate metals in their shoots and especially high tolerance to heavy metals.Since Indonesia has abundant plant diversity, it is believed that some of them are potential to be used as phytoremediator.This research was carried out to study the potential of three species of grasses in accumulating Pb and Cn. The treatments were arranged on Randomized Complete Block Design (factorial design). The first treatment are species of grass: 1) Cynodon dactylon Pers., 2)Cyperus sp. and 3) Ischaemum timorense Kith.; the second treatment is planting media i.e. 1) tailing soil, 2) soil from wildmining (mining activities run by unexpected miners) and 3) top soil and the third is organic fertilizer: 1) manure, 2) compost and 3) no fertilizer.The resultsshowed that all of the three grasses are potential to accumulate Pb and Cn. Organic fertilizer mixed on planting media is significantly affected the growth of grasses and increasing the accumulation of Cn on leaf of Cyperus sp. and I.timorense. While no evidence in increasing Pb accumulation on all of those three grasses species

Abstract

Isolation of endophytic fungi was done to find alternative microorganisms as antifungal agent against Fusarium oxysporum f.sp. cubense (Foc), causing panama disease (fusarium wilt) on Musa spp. The research objectives were 1) to isolate and identify endophytic fungi colonize cavendish (AAA) and rejang (AA) bananas growing on PT Natural Tropical Fruit (NTF) Plantation in East Lampung; and 2) to evaluate for their antagonistic activity against Foc under in vitro conditions. The results indicated 46 isolates of endophytic fungi that were isolated from leaves, saplings and petioles of cavendish banana; and leaves and petioles of rejang banana. The isolated endophytic fungi belonging to the group of Colletotrichum, Fusarium, Guignardia, Penicillium, Talaromyces and non sporulating endophytic fungi that were classified as unidentified isolate. Fourteen isolates (30.43 %) of those 46 fungi isolates tested, showed varying degree of antagonism to Foc. The best three isolates that have strong antagonistic activities were Talaromyces sp. 27-4 (M), unidentified 23-3/11 (B) and unidentified 26-5/K (L). Fusarium oxysporum 22-3/F (I), Penicillium sp. 20-2/H (J), Talaromyces sp. 27-4 (M) and unidentified 21-1/6 (A) inhibited the growth of Foc by producing both volatile and unvolatile metabolites. The strongest inhibition (53.17 %) by volatile inhibitory subtance was produced by F. oxysporum 22-3/F (I), while the strongest inhibition (65.98 %)by unvolatile inhibitory subtance was produced by Penicillium sp. 20-2/H (J).

Abstract

The endophytic fungus Diaporthe sp.E show a unique ability to biotransform (-)-epicatechin into (-)-(2R,3R,4R)-leucocyanidin in a semisynthetic medium. Extension of the incubation time gave a major product (-)-(2R,35)-dihydroquercetin which was identified by spectroscopic methods.

S. KADARSAN, E. PURWANINGSIH, S. HARTINI, I.BUDIARTI & A. SAIM 1986. The pattern of parasite infestation on rats at the Bogor Botanical Garden.Berita Biologi 3(4): 173 - 177. Three species of rats namely Rattus exulans, R. r. diardi and R. tiomanicus inhabiting the Bogor Botanical Garden were investigated with respect to their ectoand endoparasite fauna.All three species were infested with Laelaps nutalli, Echinolaelaps echidninus (Acarina); Hoplopleura pacifica and Polyplax reclinata (Anoplura); Xenopsylla cheopis (Siphoriaptera);Hydatigera taeniaefortnis and Viktorokara sp.(Helminth).Additional parasites were Poecilochinis sp., Polyplax spinulosa and Beaveria sp.,a new and yet to be described Troglotrematid Trematode found only R.tiomanicus.The rate of infestation is in part dependent on the age and sex of the host which is seemingly associated with the mobility and food searching capability of the host Time may play an additional role as well.

Abstract

The diversity of wild Begonia in West Sumatra is not well understood, while the habitat of Begonia has continuedly decreased by human activity or natural disaster. Therefore, some species are seriously undert hreat. Examinations of Begonia spp. were carried out using herbarium specimens from Andalas University Herbarium (ANDA), Herbarium Bogoriense (BO) and some field works in West Sumatra were conducted. A total of 33 species of Begonia were collected and identified as species level and could be used for identied Begonia species from West Sumatra.

Abstract

Bacillus sp diisolasi dari tanah Taman Nasional Gunung Halimun. Dalam media tumbuh yang mengandung Ca3(PO4)2 bakteri membentuk zona bening disekitar koloni.Glukosa digunakan dengan cepat selama kultivasi.Tinggi konsentrasi fosfat terlarut yang dibebaskan selama fase pertumbuhan menunjukkan bahwa bakteri mampu memacu pelarutan Ca3(PO4)2. Selama fase pertumbuhan terjadi hidrolisa organik fosfat (phenyl phosphate) menghasilkan phenol dan fosfat hal ini menunjukkan,bahwa Bacillus sp mampu menggunakan organik fosfat.Selama kultivasi terjadi penurunan pH sejalan dengan pelarutan Ca3(PO4)2.

Abstract

Cultivation of an endophytic fungus Schizophyllum sp.D, isolated from a tea plant Camellia sinensis (L.) O.K. in liquid medium PDB, on a rotary shaker at 100 rpm at room temperature (26 - 30 oC) produced a major metabolite with a production capacity of 56.7 mg/L. Structure elucidation based on MS, NMR spectra and published data showed that metabolite is nerolidol. This chemical compounds is one of important aromatic chemical constituent that contribute to tea aroma and defense system in a tea plant.
