Abstract

Indonesia has known to have several fiber plants used as rope, craft and clothing material. The literature study, observations well as interview with local community in several places in Sumatra, Kalimantan, Moluccas and Sulawesi suggested that there were nine fiber plant species that were used as clothing material in the past. But clothing material from the bark of Broussonetia papyrifera (L.)L’Her. ex Vent.,“kumpe”, is still being fabricated and used in Cental Sulawesi up to now.Two of those nine fiber plant species for clothing material had good economic value namely Boehmeria nivea (L.) Gaudich and Broussonetia papyrifera (L.) L’Her. ex Vent.

Abstract

Research was conducted to identify the fungal isolate G.23 which produces b-glucan from the Biopharmacy Laboratorium's collection.Indonesian Institute of Sciences (LIP1) based on the sequence of the Internal Transcribed Spacer (ITS) regions.DNA was isolated from mycelia and the ITS region was amplified by Polymerase Chain Reaction (PCR) with ITS1 and ITS4 primers. The PCR product was purified using the QIAquick PCR Purification kit (Qiagen). BigDye terminator cycle sequencing Ready Reaction Kit (Perkin Elmer Applied Biosystem) was used and the product was purified with the AutoSEQ G-50 Kit (Qiagen).The sequence obtained analysed using Basic Local Alignment Search Tool nucleotide (BLAST)n homology search.The BLASTn result showed that the fungal isolate G.23 belongs to the genus Aspergillus. Taxa closely related to this isolate were Aspergillus elegans,A. ochraceus and A.sclerotiorum with 96% sequence homology.ClustalX was used for sequence-alignment. Phylogenetic analysis was constructed using the Neighbour Joining (NJ) method with Kimura two parameters. The phylogenetic tree obtained showed that fungal isolate G.23 separated from A. elegans, A. ochraceus and A. sclerotiorum which indicated that fungal G.23 belonged to a different spesies.Morphological observation on culture and microscopic appearance of the fungal isolate G.23 supported that this isolate differs from A. elegans, A. ochraceus and A. sclerotiorum.

Abstract

M. DJAJASASMITA. 1987. The apple-snail Pilaampulacea: its food and reproduction (Gastropoda: ampullariidaej. Berita Biologi 3(7) : 342 - 346. The food and reproduction of the apple-snail Pila ampullacea have been studied in the laboratory, reared in aquarium, fed with dead papaya leaves (Carica papaya) and water hyacinths (Eichhomia. crassipes); shrimp crips and fish pellets which are fed by way of trial, were readily eaten.The eggs, 5-10 mm in diameter, are laid in clusters of 15-50 or more, on the aquarium walls about 10 cm off water level. In its natural habitat, in Lake Maja; West Java, the eggs clusters are found stickedon the stems of the kirai palms (Metroxylon rumphii) (which grow densely in the lake) about 75 cm above water level.In the ponds of the Bogor Botanical Garden, the egg cluster were attached on the stems of the aquatic plants (Cyperus papyrus, Hanguana malayana, Sagittaria lancifolia and Thali geniculata) 20-70 cm off the water edge.The egg cluster is covered by a calcareous layer, it is presumed, that this calcareous covering may absorbed dew/rain water, to prevent the eggs desiccating, Some egg clusters laid in the laboratory which are not provided by calcareous layer (it seems due to the physiological disturbance) were desiccating and failed to hatch. The females may deposit 1-2 egg clusters monthly in the rainy season, or may not at,all in the dry season. The peak of the spawning is coincided with the rainy season.

Abstract

A physiological study on Gewang or Tune (Corypha utan Lamk.),a drought resistant and still-wild native palm species in the savanna area of Timor island, East Nusa Tenggara (NTT),shows that this species undergoes a sharp fluctuation in her diurnal water potential (Wd).In two different sites,the early morning Wd shows a less negative values (-1,9 bars to -5,40 bars); however in the afternoon, due to environmental stresses, the Wd drastically dropped to between (-9,7 bars and -17,3 bars).Interestingly,Gewang successfully regulates her Wd during the afternoon and along the night as their d went back normal levels, due to quickly recharged of their Vd to less negative values (-2,1 bar to -8,5 bars).The values of d differs between two sites, however they have similar patterns when comes to recharge their WA.This phenomenon is in line with their relative water content (RWC), as shown a fluctuation following the drops and recharge of Vd.This figure indicates that Gewang may develop mechanism of osmotic adjustment to cope with environmental especially water stress, thus proves her ability to lead as a drought resistant and evergreen species.

Abstract

Water management in acid sulfate soil can increase the productivity of land and crops, but the element of poison leaching into drainage channels gives negative impact on the environment. One approach to improve water quality is to filter or absorb the poison element. Purun tikus (Eleocharis dulcis) can act as a biofilter to improve water quality. The purpose of this study is to get biofilter technology (purun tikus) to reduce the levels of Fe, SO4 and increase the pH of the water. The experiment was conducted in greenhouse of Indonesian Swampland Agriculture Research Institute, Banjarbaru, South Kalimantan. Treatment was arranged in a factorial randomized block design with three replications.The first factor was the density of the biofilter ,consisted of: 1) 25%, 2) 50%, and 3) 100%, The second factor was the length of contact of water with biofilter that consisted of: 1). 12 hours, 2) 24 hours, and 3) 36 hours. The results showed that the density of purun tikus 50% in greenhouse experiments can decreased the concentration of Fe at 76.5%.

Abstract

Jenis talas Colocasia esculenta (L.) Schott di Jawa mempunyai dua varietas botani yaitu C.esculenta var. esculenta yang umumnya tumbuh di dataian rendah dan C. esculenta var. antiquorum (Schott) Hubbard & Rehdei yang tumbuh liar di tepi-tepi sungai lereng pegunungan. Jenis lainnya yaitu C. gigantea (Bl.) Hook. f. (talas padang, sontrang) biasa tumbuh liar di hutan jati dan tawa. Perbungaan talas-talas budidaya jarang dihasilkan sehingga penanaman daii biji tidak lazim dilakukan dan perbanyakan tanaman lebih dikenal dengan anakan. Kaiena itu penelitian yang menyangkut biologi pembungaan dan penyerbukan kedua jenis Colocasia tersebut sampai saat ini sedikit sekali yang telah dilapoikan.

Abstract

Chinese hamsters ovary (CHO) and its derivative such as CHO-DXB11 cells, CHO-K1, CHO-DG44 and CHO-S are mammalian cells that are often used for production of therapeutic protein drugs. The CHO cells often used for protein production have several advantages including 1) host cells that are safe to use in drug production, 2) the level of production of proteins produced can be increased by amplifying genes using methotrexate (MTX), 3) having the capacity to make post-translation modificationsand 4) CHO cells can be adapted to grow in suspension. The high need for protein-based drugs triggers the development of basic knowledge and innovation in production of recombinant proteins. The impressive technological advances in CHO cell technology have made these cells can be used to produce proteins around 10 g/liter in order to meet the market demand. The first protein successfully produced using CHO mammalian cells was the therapeutic Tissue Plasminogen Activator (r-tPA, Activase) protein used for stroke patients. The presence of this drug is quickly followed by several other types of drugs. In this review, history of development of CHO cells, the contribution of CHO cells to basic research, progress of effective line cell screening and development technology are discussed.
