“…This was comparable with the chemical components reported by other researchers [3,5,[7][8], except for the hemicellulose content which was higher than that in the three reports [3,5,7], but almost the same as that reported by Goh et al [8]. The change of these chemical components in OPF after pretreatment using P. chrysosporium and T. versicolor is presented in Table 1.…”

“…The OPF contains sugar, such as fructose, glucose and sucrose [5]. Some of these sugar types, which might be counted as ethanol-benzene extract, were removed when the OPF was washed after fungal pretreatment.…”

“…Analysis of cold-water extract of the original OPF shows that the OPF fiber contains 9.36% cold water extract. The fresh OPF also contains some simple sugars, such as glucose, sucrose and fructose [5]. These reducing sugars in the original samples of OPF fiber might also contribute to the reducing sugar content of the saccharified original OPF fiber samples (Control 1).…”

“…Another potential use of OPF is for production of bioethanol. The fresh OPF can be directly pressed, and the juice obtained contains sugar; therefore, it can be directly fermented to ethanol [5]. Besides that, the frond fiber can be used as cellulose feedstock for bioethanol.…”

“…Besides that, the frond fiber can be used as cellulose feedstock for bioethanol. The OPF fiber contains 15.5% lignin, 41.7% cellulose, and 16.4% hemicellulose [5], while oil palm empty fruit bunch (OP EFB) fiber contains more lignin (27.6-32.5%) and comparable amount of cellulose (41.3-46.5%) [6]. Thus, based on the main chemical components of the fiber, OPF fiber is more potential than OP EFB fiber as bioethanol feedstock.…”

Oil palm frond is one type of lignocellulosic biomass abundantly and daily available in Indonesia. It contains cellulose which can be converted to glucose, and further processed to produce different kinds of value -added products. The aim of this research is to study the effects of biological pretreatment of oil palm frond (OPF) fiber using Phanerochaete chrysosporium and Trametes versicolor on the enzymatic saccharification of the biomass. The OPF fiber (40-60 mesh sizes) was inoculated with cultures of the two fungi and incubated at 27 °C for 4 weeks. The samples were taken after 1, 2, 3, and 4 weeks of incubation. Chemical components of the biomass after pretreatment were analyzed. The saccharification of the pretreated samples using cellulase and β-glucosidase was performed in a water bath shaker at 50 °C for 48 hours. The concentration of reducing sugar increased with increasing of incubation time, either in those pretreated with culture of P. chrysosporium or with T. versicolor. Pretreatment of OPF fiber using single culture of T. versicolor for 4 weeks gave the highest reducing sugar yield (12.61% of dry biomass). AbstrakPretreatment Biologis Serat Pelepah Kelapa Sawit Menggunakan Jamur Pelapuk Putih untuk Sakarifikasi Enzimatis. Pelepah kelapa sawit (PKS) merupakan salah satu biomassa lignoselulosa yang tersedia cukup melimpah di Indonesia. Serat PKS mengandung selulosa yang dapat dikonversi menjadi glukosa, dan selanjutnya dapat diproses lebih lanjut untuk menghasilkan berbagai produk yang mempunyai nilai tambah. Tujuan penelitian ini adalah untuk mempelajari pengaruh pretreatment biologis pada serat PKS menggunakan Phanerochaete chrysosporium dan Trametes versicolor terhadap hasil sakarifikasinya. Serat PKS (40-60 mesh) diinokulasi dengan kedua kultur jamur dan diinkubasi pada suhu 27 °C selama 4 minggu. Contoh diambil setelah masa inkubasi selama 1, 2, 3, dan 4 minggu dan dianalisis kandungan komponen kimianya. Sakarifikasi PKS yang telah diberi pretreatment menggunakan selulase 20 FPU/g substrat dan β-glukosidase 14 CBU/g substrat dilakukan dalam water bath shaker pada suhu 50 °C selama 48 jam. Konsentrasi gula pereduksi meningkat dengan semakin lamanya waktu inkubasi, baik pada contoh dengan perlakuan P. chrysosporium maupun dengan T. versicolor. Pretreatment serat PKS menggunakan kultur tunggal T. versicolor selama 4 minggu menghasilkan rendemen gula pereduksi tertinggi (12,61% dari berat kering biomassa).

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
