Studies on the utilization of palm oil wastes as the substrates for butanol fermentation

Studies were made on the feasibility of using palm oil wastes as feedstocks for the production of butanol and as a means of controlling pollution.
Of the various palm oil wastes, clarification sludge was found to be the best substrate for the fermentation by Clostridium aetobutylicum, but the fermentatation produced only acidic products due to the low fermentable sugar content of the sludge.
About 74mM of butanol was produced along with other products, from the fermentation of clarification sludge supplemented with 20 g/l of starch.

Comparison of palm kernel stearin SFC Measurements at 30 degree calcius by Wideline and pulse NMR

The solid fat content (SFC) of palm kernel stearin was measured using both wideline and pulse nuclear magnetic resonance (NMR) spectrometers. For pulse NMR both the Direct Display Method and the Indirect Calculation Method were applied. The results obtained by the two methods showed large discrepancies at 30°C. The Direct Display Method consistently gave significantly lower values at the critical temperature of 30°C than did the Indirect Calculation Method, while the latter gave results comparable to those by the wideline NMR Method. There were no significant differences at the other temperatures. It is recommended that either the Indirect Calculation Method of pulse NMR or wideline NMR be used in the measurement of the SFC of palm kernel stearin.

Biology and performance of Surinam Elaeis Oleifera (H.B.K.) Cortes

The Elaeis oleifera palms found in Surinam and Northern Brazil are exceptional among oleifera on account of their small size, very slow growth in height and small inflorescences on long peduncles. The abscission of their male flowers, shortly after anthesis, is a unique characteristic not found in other oleifera nor in E. guineensis. Fruit bunch yields of the Surinam oleifera are comparatively inferior due to low bunch weight and bunch number. There is relatively less parthenocarpy and the fertile fruits have more pulp than in Central American or Colombian oleifera but the pulp has considerably less oil. The oil, furthermore,is more saturated. Interspecific hybrids between the surinam E. oleifera and E. guineensis are markedly more fertile than those using other oleifera and hence are potentially promising. The hybrids are smaller and more compact and their yields can be high, but the mesocarp oil content requires improvement through breeding and selection.

Research strategies and advances in oil palm cell and tissue culture

Cloning of palm oil, in conjunction with breeding and selection, could lead to rapid increases in yield and improvements in oil quality, as well as vegetative features. Oil palm cannot be cloned by conventional horticultural methods; tissue culture appears to the only feasible approach. Methods and strategies for large scale propagation of oil palm are described. Fruit abnormalities seen in some clones are described and their likely causes are discussed in light of available evidence.
