“…It is of major interest due to its renewable and sustainable nature as a feedstock to replace fossil fuels for the production of biofuels and chemicals [2]. The use of agricultural residues including rice straw, nut shell, maize stover and oil palm empty fruit bunch (EFB) as feedstocks are favourable as they are not used for food and are not compromising food security [3][4][5]. Palm oil is the most widely used edible oil and the waste generated at palm oil mills is currently creating a major disposal problem particularly EFB, shells, and fruit palm kernel, in addition to waste produced in the plantations, such as palm trunks and fronds.…”

“…Palm oil is the most widely used edible oil and the waste generated at palm oil mills is currently creating a major disposal problem particularly EFB, shells, and fruit palm kernel, in addition to waste produced in the plantations, such as palm trunks and fronds. The generation of large amounts of lignocellulosic waste are mainly in the form of EFB [5]. The valorization of this abundant waste is highly encouraged in countries like Malaysia and Indonesia.…”

Genomic analysis of a lignocellulose degrading strain from the underexplored genus Meridianimaribacter

et al. 2020

The genus Meridianimaribacter is one of the least-studied genera within Cytophaga-Flavobacteria. To date, no genomic analysis of Meridianimaribacter has been reported. In this study, Meridianimar ibacter sp. strain CL38, a lignocellulose degrading halophile was isolated from mangrove soil. The genome of strain CL38 was sequenced and analyzed. The assembled genome contains 17 contigs with 3.33 Mbp, a GC content of 33.13% and a total of 2982 genes predicted. Lignocellulose degrading enzymes such as cellulases (GH3, 5, 9, 16, 74 and 144), xylanases (GH43 and CE4) and mannanases (GH5, 26, 27 and 130) are encoded in the genome. Furthermore, strain CL38 demonstrated its ability to decompose empty fruit bunch, a lignocellulosic waste residue arising from palm oil industry. The genome information coupled with experimental studies confirmed the ability of strain CL38 to degrade lignocellulosic biomass. Therefore, Meridianimar ibacter sp. strain CL38, with its halotolerance, could be useful for seawater based lignocellulosic biorefining.

“…In the present work, the maximum temperatures measured during the treatments were within the mesophile range (29-38°C). Thus, the pathogen reduction in the present work could be explained as the result of a series of factors other than thermophile temperatures, such as competition for nutrients, oxygen, and space with suppressor microorganisms; the excretion of secondary metabolites by fungi (More et al 2010;Shafawati and Siddiquee 2013); and the presence of ammonia (Méndez et al 2008). To determine whether there were suppressor fungi in the treatments, isolation and identification of the fungi present were performed, and fungi of the genera Penicillium, Rhizopus, Paecilomyces, and Fusariella were found.…”

The goal of the present research work was to assess the management of sewage sludge (SS) by composting using fermented water hyacinth (WHferm) as an amendment. The water hyacinth was fermented, and a higher production of volatile fatty acids (VFAs) (782.67 mg L(-1)) and soluble organic carbon (CSOL) (4788.34 mg L(-1)) was obtained using a particle size of 7 mm compared to 50 mm. For composting, four treatments (10 kg fresh weight each) were evaluated: treatment A (100 % SS + 0 % WHferm), treatment B (75 % SS + 25 % WHferm), treatment C (50 % SS + 50 % WHferm), and treatment D (25 % SS + 75 % WHferm). The WHferm added to SS, especially in treatments C (50 %) and D (75 %), increased the initial contents of organic matter (OM), organic carbon (CORG), CSOL, the C/N ratio, and the germination index (GI). The heavy metal content (HMC) (As, Cd, Cr, Cu, Hg, Ni, Pb, and Zn) at the beginning was below the maximum allowed by USEPA regulations. All of the samples were free of Salmonella sp. from the beginning. The reduction of the CORG, CSOL, total Kjeldahl nitrogen (TKN), and C/N ratio indicated the degradation of the OM by day 198. The treatments with WHferm (B, C, and D) yielded higher values of electrical conductivity, cation exchange capacity, and GI than SS at day 198. No significant differences were observed in GI among the treatments with WHferm. The fecal coliforms were eliminated (<3 MPN g(-1)) and the helminths were reduced to ≤5 eggs/2 g during the process. The competition for nutrients and the presence of suppressive fungi of the genera Penicillium, Rhizopus, Paecilomyces (penicillin producers), and Fusariella isolated from the compost may have promoted the elimination of pathogens since no thermophile temperatures were obtained. WHferm as an amendment in the composting of SS improved the characteristics of the final product, especially when it was used in proportions of 25 and 50 %. An excellent product was obtained in terms of HMC, and the product was B class in terms of pathogens.

Sustainable land use has been identified as one way of tackling challenges related to climate change, population expansion, food crisis and environmental pollution. Disposal of oil palm fresh fruit bunch (FFB) solid wastes is becoming a challenge with an increased demand and production of palm oil. Whilst this poses a challenge, it could be turned into an opportunity by utilising it as a resource and fully valorise it to meet soil and crop demands. This review presents the potentials of FFB solid wastes, which include empty fruit bunch (EFB), mesocarp fibre (MF), palm kernel shell (PKS), as soil ameliorants. The major findings are the following: 1) pyrolysis, gasification, combustion, and composting are processes that can enhance the value of FFB solid wastes.
