Most of industrial lipases are derived from microbial sources, following by a wide variety of plants. Among plant lipases, lipase from Carica papaya latex has been the focus of intense and growing research due to low cost, easy acceptance by consumers and its unique characteristics. This enzyme has been successfully applied for lipid modification and synthesis of some organic compounds. However, research for its molecular structure has been limited due to the difficulty to isolate the enzyme from the latex matrix. In this study, we suggested a modified approach using sodium lauroyl sarcosinate to solubilize the latex, then the protein was precipitated by ammonium sulphate. We also carried out the characterization of the lipase obtained from Carica papaya latex. The results showed that freeze-drying the fresh latex could improve significantly lipase activity of latex powder in comparison with sun-drying or oven-drying. The zwitterion sodium lauroyl sarcosinate could solubilize nearly 50% of the latex and the achieved supernatant exhibited great lipase activity. There was no need to use an organic solvent to delipidate the latex prior to solubilization with sodium lauroyl sarcosinate due to possible denaturation of enzymes. The proteins which were fractionally precipitated with 50 – 60%, 60 – 70% and 70 – 80% ammonium sulphate saturation showed lipolytic activity. The fraction from 50 – 60% saturation with the greatest mass was subjected to ion exchange chromatography, SDS electrophoresis and kinetic parameter determination. The results showed the presence of two proteins with molecular mass ranging from 35 kDa to 55 kDa and both presented lipase activity. The Km and Vmax of the lipase fraction from 50 – 60% saturation was 1.12 mM and 1.2 x 10-6 mM.min-1.mL-1 respectively. So, the freeze-drying of papaya latex could help to preserve its lipase activity and the usage of sodium lauroyl sarcosinate could improve the isolation of the lipase from the papaya latex and pave the way for research on the molecular structure of Carica papaya latex lipases.

Carica Papaya Latex

The papaya (Carica papaya), of the family Caricaceae, is a tree-like tropical plant, native to Central and South America. Papaya cultivation extends to all warm and humid countries. The present study consists in using the solution of raw Carica papaya latex (SLCP) cultivated in Benin as a natural biodegradable flocculant in a physico-chemical process to treat liquid discharges loaded with metals including iron, copper, zinc, and manganese; and suspended matter, and also to test its efficiency against other products commonly used in wastewater treatment. The tests were carried out on water samples from the wastewater collector that runs through the Agla district in Cotonou. The comparative study with a commonly used flocculant, aluminium sulphate, showed outstanding competitiveness with a high flocculation power for the solution of Carica papaya raw latex. In six water samples from the collector with average concentrations of iron, copper, zinc and manganese of 18.20 mg/L ; 2.50mg/L ; 3.80 mg/L and 3.70 mg/L respectively, the percentages of metal removal exceeded 90% for iron and manganese and around 85% for copper and zinc with the combination FeCl3 + SLCP. The NaOH + SLCP combination showed a very significant effect on the removal of metals (96% reduction) and suspended matter.
