Bioconversion process for microbial treatment of palm oil mill effluent to produce citric acid
Published 2006“…It is estimated that for 1 tonne of crude palm oil produced, 5-7.5 tonnes of water is required and more than 50% of water end up as Palm Oil Mill Effluent (POME). The raw or partially treated POME has an extremely high content of degradable organic matter along with some unrecovered palm oil, which can cause severe pollution of waterways due to oxygen depletion and other related effects. …”

Investigations of the causes of chatter in computer aided manufacturing process during end milling operation
Published 2008“…The most vibrating components during computer aided milling machine operation have been identified. It has been found that chatter appears in the system as a resonance during cutting when the chip serration frequency is equal or any integer multiple of the prominent natural frequency of the system components like spindle, tool holder.…”

Optimization of the nutrient supplements for cellulase production with the basal medium palm oil mill effluent
Published 2009“…A statistical optimization was studied to design a media composition to produce optimum cellulolytic enzyme where palm oil mill effluent (POME) as a basal medium and filamentous fungus, Trichoderma reesei RUT-C30 were used in the liquid state bioconversion(LSB). 2% (w/v) total suspended solid, TSS, of the POME supplemented with 1% (w/v) cellulose, 0.5%(w/v) peptone and 0.02% (v/v) Tween 80 was estimated to produce the optimum CMCase activity of 18.53 U/ml through the statistical analysis followed by the faced centered central composite design(FCCCD). …”
