“…The pH of control was 3.9 whereas, with the increased treatment time and intensity, the pH of E. tereticornis wood slightly decreased. When wood becomes acidic, wood durability is improved against biodegradable agencies such as insects, pests and fungi (Bahmani et al 2016, Kaur et al 2016. The results showed insignificant differences between T-1A (3.7), T-2A (3.7) and T-3A (3.6) treatments.…”

“…The comparison for the composition of starting biomass and the composition of pyrolysis distillates on molecular level is considered out of the scope of this study. Simple distillate constituents, such as acetic acid, have also been found to delay wood decay (Bahmani et al, 2016). Acetic anhydride and furfural alcohol used for creating acetylated and furfuralated wood of high decay resistance also embody the benefits of acetic acid, furfural, and HMF in distillates (Mantanis, 2017).…”

“…Propionic acid has been tested against moulds by Kiesel as early as in 1913. A study by Bahmani et al (2016) showed recently that propionic acid acts against several molds and decay by Pleurotus ostreatus and C. puteana in date palm (Phoenix dactylifera) and oil palm (Elaeis guineensis). Our analysis agree with these results and highlights that the fungal inhibition caused by propionic acid alone is statistically the same as the inhibition caused by the copper reference, as they do not differ significantly.…”

The quest for cleaner wood preservatives is one of the major foci of contemporary wood science. Pyrolysis distillates are potential intermediates to extract large volumes of bioactive chemicals. The aim of this study was to characterize pyrolysis distillates from spruce and birch bark and hemp and test different fractions as potential antifungals to prevent wood decay. In all the fungi tested, distillates of spruce caused over 40% inhibition at 0.1% concentration; 19 significant inhibition could be observed when the concentration of the distillates in growth 20 media was 1%. The results indicate that inhibition was caused by the synergetic action of 21 different chemicals in the pyrolysis distillates. When the individual components were 22 considered, propionic acid exhibited a very high inhibitory effect against the wood decay fungi. 23 2 The high inhibition of the pyrolysis distillates at 1% and lower concentrations demonstrate that pyrolysis liquids could be a source for formulations of sustainable wood preservatives.

“…Eighteen months after felling, 28% of the dry mass of the trunk is still preserved 15 . High sugar and moisture content makes oil palm trunks susceptible to fungi and insect infestation, especially in the outer parts of the trunk, while the inner part of the trunk is rather susceptible to blue‐stain fungi 16,17 . Basal stem rot disease caused by Ganoderma boninense is a major problem in the oil palm industry.…”

“…The oil palm trunks display high moisture content, up to 80%, especially in the inner parts, and high sugar content, as well as different material properties in comparison to normal wood. They are therefore not particularly suitable for wood products 16,19,20 . Only a small amount of the trunk is exploited to manufacture veneer plywood or furniture.…”

In 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. © 2021 The Authors Biofuels, Bioproducts and Biorefining published by Society of Chemical Industry and John Wiley & Sons, Ltd
