PRELIMINARY STUDY OF LIGNIN UTILIZATION FROM THE PALM OIL EMPTY FRUIT BUNCH (EFB) DELIGNIFICATION LIQUOR TO VANILLIN THROUGH BIOLOGICAL ROUTE
Indonesia is one of the top palm oil producers in the world with a production capacity of 49,12 million tonnes of Fresh Fruit Bunch (FFB) in 2020. About 10,81 million tonnes of palm oil Empty Fruit Bunch (EFB) containing 21,28-22,10% lignin will be produced. Lignin consists of various aromatic...

| Summary: | Indonesia is one of the top palm oil producers in the world with a production
capacity of 49,12 million tonnes of Fresh Fruit Bunch (FFB) in 2020. About 10,81
million tonnes of palm oil Empty Fruit Bunch (EFB) containing 21,28-22,10%
lignin will be produced. Lignin consists of various aromatic monomers which can
be converted to various commercial derivative products, so it has high economic
value. However, this great potential of lignin has not been fully utilized in
Indonesia.
Vanillin is the most popular flavoring ingredients in the world and has been widely
used in food, perfume, pharmaceutical, and cosmetic industry with a global market
potential of 480,1 million USD. Vanillin can be produced through catalytic or
biological processing of lignin. Compared to the catalytic processing which has
several drawbacks on energy consumption and environmental aspects, biological
lignin processing has a wider range of vanillin yields depending on microorganism
being used, can be done in ambient temperature and pressure, and environmental
friendly. However, it has not been implemented on an industrial scale.
In this research, the vanillin production from soluble lignin of EFB delignification
liquor through biological route will be developed. This development was focused
on the lignin-model compound quantification in EFB delignification liquor,
analysis of significant factors affecting vanillin mass yield and productivity; the
fermentation bacteria, inhibitor concentration, and EFB delignification liquor
source. The fermentation of hydrothermal EFB delignification liquor using
Pseudomonas putida DSM 6125 with 5 mM DTT presence results on 0.0009 ±
0.0012% vanillin mass yield and 0.17 ± 0.22 ppm/hour vanillin productivity, while
the other experimental results give negative results on vanillin mass yield and
productivity. |
