Abstract

Plant cell walls are unique, complex, diverse and dynamic structures that change throughout the process of cell division, growth and differentiation. Plant cell walls are not only a single key determinant of overall plant form, but they also play an important role in sustaining human societies. Evidence of how cell walls are crucial for plant structure is that without cell walls, plants would be elastic piles of protoplasm, more like slime moulds than stately trees. Unlike animals, in which specialized skeletal system provides physical support, the strength, flexibility, texture and overall shape of higher plants depend on the cumulative properties of walls. Moreover, plants are composed of approximately 35-40 cell types that are distinguished from each other by the chemistry and organization of their walls. In human societies, cell walls directly affect the quality of most plant-based products, including paper and pulping, textile, food quality and texture, dietary fibre, malting and brewing and bioethanol production (Cosgrove, 2005; Farrokhi et al., 2006).The chemical structure of most wall components has been intensively studied and defined in detail, however, the enzymes responsible for cell wall biosynthesis and also its restructure remain poorly understood. However, currently, there has been real progress towards understanding the cell wall biosynthesis, using various emerging approaches, such as genetic and biochemical approaches (Farrokhi et al., 2006).This review will elaborate on recent advances in our knowledge of the structure cell walls of flowering plants, particularly the structure of primary cell walls. Moreover, this review will also explain the current knowledge towards understanding primary wall biosynthesis and also the future application of cell wall study in biotechnology.

Abstract

Hutan mangrove atau bakau merupakan salah satu bentuk komunitas yang ada di daerah pasang surut dan khas yang mendukung kehidupan biota lain. Hock and Sasekumar (1979) melaporkan adanya primata yang hidup di hutan mangrove. Primata tersebut adalah monyet ekor panjang (Macaca fascicularis) dan lutung (Presbytis cristata). Selain itu, jenis-jenis burung, kepiting (Aratus pisonii, Erickson et al., 2004), semut (Oecophylla smaragdina, Offenberg et al., 2004). Selain itu, hutan mangrove ini sangat penting sebagai tempat berbiaknya jenis-jenis invertebrate dan ikan.

Abstract

The objective of this research was to investigate the capabilities of bacteria isolated from industrial tanning waste to degrade TCMTB. The bacteria was initialy screened, based on their tolerance to various concentration of TCMTB using paper disk method. Then, those strains were further analyzed in terms of their ability to produce ammonia (NH4+) and sulphate (SO42-). Degradation activity was measured based on remaining residue of TCMTB analyzed using HPLC. The superior strain that showed the highest activity in degradation of TCMTB then were characterized and identified based on phenotypic and 16S rDNA sequence analysis. The result of the experiments showed that four selected strains among seven were choosen based on their high tolerance to various concentration of TCMTB, namely PK1, PK2, PK4 and PK6. All four strains showed the ability to produce ammonia and sulphate but three of which, namely PK2, PK4 and PK6 showed the high capability to degrade TCMTB. One particular strain (PK2) was observed to degrade TCMTB 40.8% within 7 days, but the others were less than 30%. Based on the phenotypic characteristics and 16S rDNA sequence analysis, the best strains (PK2) was identified to be member of genus Pseudomonas.

Abstract

Rattans are spiny climbing palms in the Old World tropics and subtropics. Some species are the source of cane for the cane furniture industry in Indonesia. The large number of rattan species and their wide geographical range is matched by great ecological diversity. The restriction of rattan species to different climatic zones and altitudinal range suggests that these species may have precise climatic requirements and also altitudes. The research was conducted on upland and lowland of natural forest in South Kalimantan. The data collection used survey with transect method. Volume of rattans in upland forest was relatively lower than lowland forest. In altitudinal range in South Kalimantan, rattans were found from sea-level up to 870 m, the highest altitude record being held by Calamus javensis, Daemonorops micracantha, Calamus pilocellus, and Calamus sp. (rotan tunggal). While the lowest altitude record was occupied by Calamus trachycoleus. Rattans in natural forest require light intensity, humidity and temperature were 18– 65%, 60 – 70%, 28 – 33oC, respectively.

Abstract

Stress condition has been reported decreased the level of intracellular antioxidant, especially superoxide dismutase (SOD). The condition can lead to certain cell impairment and finally can reach to the degenerative processes, such as aging and carcinogenesis. We need several alternative treatments to solve the severe problem under antioxidant defiency status caused by stress condition. The aim of the study was to observe the effect of α-tocopherol on increasing the profile of superoxide dismutase (SOD) in the kidney of rats under stress condition. The stress condition was achieved by five days fasting together with smimming for 5 min/day and only drinking distiled water ad libitum. α-tocopherol was orally administrated at a dose of 60 mg/Kg/BW/day for seven days. By measuring SOD activity and Cu,Zn-SOD imunohistochemically, showed that α-tocopherol has effect on increasing the profile of intracellular antioxidant in the rats kidney tissue under stress condition.

Abstract

Guild composition and niche breadth are important point on avian studies. This paper describes the guild composition and niche breadth of understorey bird in Sipisang, West Sumatra. The study was conducted since May 2002 until October 2004 for approximately 10 days each month (totally 284 days or 51.120 net.hours). Fifteen mist nets were operated on ground level separately on three locations, which made 60 m line each. Mist nets were operated from 6.00 AM until 18.00 PM, and checked every two hours. The captured birds were identified, ringed, measured, weighted, photographed and released. In total 1061 individuals were captured during the study; those birds belong to 103 Species and 28 families. Based on guild, study area was dominated by insectivore-frugivore birds (IF) both in species and individual level. Meanwhile terrestrial frugivorous (TF) became the lowest one. Insectivore-frugivore also recorded has the broadest niche breadth. The bird communities dominated by small birds, which have weight lower than 30 g.
