text: 'n recent decades, the demand for palm oil has constantly increased and with
it the cultivation of oil palms. After a period of 25 years, the oil yield of
the palm trees decreases and they are felled. The trees are cut into pieces and
remain on the plantations. However, due to their high moisture and sugar content,
fungi and molds cause problems for replanting. The use of the wood for the timber
industry is difficult due to its structural characteristics. Biotechnological
processes use microorganisms to produce relevant industrial products. The basis
for each process is a culture medium that contains all necessary nutrients, especially
carbohydrates. The culture medium makes up a high percentage of the costs, so
alternative, cheaper substrates are preferred. In this review, we show and compare
different analyses of the sap mechanically pressed from the oil palm trunk regarding
its sugar and nutrient content. The total sugar concentration in the palm sap
varies between 16.97–140 g L−1 and it is mainly composed
of glucose, fructose, and sucrose. The comparison with common nutrient media and
the results of fermentation processes already carried out on a laboratory scale
show that palm sap offers great potential as a fermentation medium for biotechnological
conversion into industrially relevant products. '
