Microbial degradation of flexible polyurethane foams by aspergillus niger and aspergillus terreus
The ability of the fungi, Aspergillus niger and Aspergillus terreus, to degrade palm-based flexible polyurethane foam was determined via the petri dish and shake flask tests. A dense fungal growth was detected by visual examination of foams inoculated on minimal nutrient agar/solution (MN)but not on the mineral salts agar/solution (MS). Both the palm-based and commercial […]
Red palm olein as a source of b-carotene and colouring agent in cake
Red palm olein (RPOo) containing a high content of carotene was compared to other vegetable oils and their blends. Blends of different ratios of RPOo and refined, bleached and deodorized palm olein (RBDPOo) were used in a cake for-mulation. The ratios were A (30:70), B (50:50), C (70:30) and D (100:0) RPOo: RBD POo. The […]
Carbon dioxide enrichment in oil palm canopies and its possible influence on photosynthesis
This paper reviews past and recent work on at- mospheric concentrations of carbon dioxide (CO2)in and above stands of oil palm.Although data is limited, atmospheric CO2 concentrations both within and above stands,determined for several plantings,showed large diurnal variations with CO2accumulating to high levels over-night.Over much of the day, higher concentrations than are generally recognized as […]
Potential application of marker assisted selection (MAS) in oil palm
In recent years, the burgeoning field of molecular biology has provided useful tools for rapid and detailed genetic analysis of higher organisms, including agricultural species. Perhaps the most widespread application of DNA markers is in the construction of genetic maps, which can be used to determine the chromosomal location of genes affecting simple and complex […]
