Since Morocco has the world’s largest reserve of phosphate mines, its phosphate rocks (PR) can be examined for their agronomic effectiveness in Malaysian soil. This study investigated the effects of various types of Moroccan phosphate rocks (MPR) as well as Egyptian phosphate rocks (EPR) on the growth performance of different oil palm genotype seedlings. Five different rates of MPR Type B was used to assess the effect of different rate of PR on oil palm seedlings’ performance; 0 mg P kg –1 (control), 50 mg P kg –1 , 100 mg P kg –1 , 200 mg P kg –1 and 400 mg P kg –1 . Meanwhile, four different types of PR were used to assess the effect of different types of PR on oil palm seedlings’ performance: MPR Type A, MPR Type B, MPR Type C, EPR and control (no PR application). The results showed that the rates and types of PR application had significant effects on the P concentration and P uptake of oil palm seedlings. MPR Type B at 100 mg P kg –1 was found to produce the optimum rate of P concentration and P uptake in the oil palm seedlings. In terms of different sources of PR, MPR Type B was found to provide oil palm seedlings with a higher concentration of P than EPR.","PeriodicalId":16613,"journal":{"name":"Journal of Oil Palm Research","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135634633","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A one-pot glass wool-pyrolysis method was developed and utilised to convert palm kernel meal into activated carbon from palm kernel meal (AC-PKM) over process temperatures 750°C for 5 hr as an adsorbent for antibiotic residues. Physicochemical properties, semi-quantitative specific surface area, surface functional group profiles, and scanning electron microscopy (SEM) were evaluated. The physicochemical properties of AC-PKM meet the standards set by SNI 06-3730-1995 with a semi-quantitative specific surface area of 751 m 2 /g. Fourier transform infrared (FTIR) analysis shows that the active functional groups are scattered on the surface of AC-PKM. The maximum adsorption capacity is 82.64 mg/g adsorbent and can be explained by the Langmuir isotherm and pseudo-second-order type I kinetic model. The thermodynamic investigation showed that the adsorption process is a spontaneous endothermic reaction. The AC-PKM can remove 26% ceftriaxone (as a model residue antibiotic) for 2 hr of contact at a neutral pH at room temperature. The results show great promise of the one-pot glass wool-pyrolysis method to produce desirable activated carbon for removing ceftriaxone (CFT) application and an alternative treatment for the reuse of palm kernel meal waste.","PeriodicalId":16613,"journal":{"name":"Journal of Oil Palm Research","volume":"271 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135273982","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The oil palm frond (OPF) juice was utilised as a low-cost raw material for BC production. The AgNPs were incorporated in the BC composite by thermal reduction of 1 mM silver nitrate for their antibacterial agent. The BC-AgNPs composite had dense nanofibrils with an average diameter of 61.5 ± 1.0 nm as shown in the field emission scanning electron microscope (FESEM) images. The composite had a crystallinity index of 86.5% and the nanoparticles had a face-centred cubic geometry with a crystal size of 26.5 nm as determined by X-ray diffraction analysis (XRD). The Ag content was 1.463 mg/100 cm 2 in the composite analysed by atomic absorption spectrophotometry (AAS). 10.4% of the total Ag content was released from AgNPs in 72 hr as measured by inductively coupled plasma mass spectrometry (ICP-MS). The composite also demonstrated excellent antibacterial action against Staphylococcus aureus, giving a 29 ± 0.8 mm inhibition zone by the disk diffusion assay. Pure BC composite exhibited no cytotoxicity effect on the HSF1184 fibroblast cells and 10%-40% BC-AgNPs composite extracts were compatible with the cell growth. The study suggests the BC-AgNPs composite is a good material for antibacterial wound dressing.","PeriodicalId":16613,"journal":{"name":"Journal of Oil Palm Research","volume":"274 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135274162","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While most studies concentrate on the organic removal from POME, the recovery of valuable resources from the effluent is infrequently described. The rising awareness of sustainability has motivated palm oil millers and academics to enhance waste management while also placing cognizance need for the resource’s recovery. POME possesses a substantial amount of oil and grease (O&G), which can be valorised into value-added products such as biofuels or phytonutrients via oil recovery. Recovering oil loss through POME not only prevents income loss but also improves downstream treatment effectiveness. In this article, the perspective of oil recovery from POME, focusing on technologies like physical separation, chemical extraction, and ultrasonic irradiation as a pre-treatment will be discussed, along with their effectiveness and limitations. Additionally, future opportunities as well as the economic viewpoint will be looked upon to provide a comprehensive outlook. Overall, this article will provide the readers with an understanding of the significance of recovering oil from POME and its potential as a sustainable resource, contributing to effective waste management and supporting a circular economy.","PeriodicalId":16613,"journal":{"name":"Journal of Oil Palm Research","volume":"25 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135320457","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Combined peracetic acid (PAA) and ultrasonication were used for OPEFB pretreatment. PAA solutions of varying strengths and duration of ultrasonication at a frequency of 37 kHz at 60°C were examined for OPEFB pretreatment. At 10% PAA for 60 min, the highest levels of cellulose (52.0 ± 0.2%), hemicellulose (39.5 ± 0.2%), and decreased lignin (11.3 ± 0.4%) were achieved. In the ideal pretreatment condition, the highest glucose levels (28 mg/g) and xylose (19 mg/g) was observed. Under a scanning electron microscope (SEM), a significant structural change in OPEFB before and after pretreatment was discovered. FTIR of OPEFB fibre had an absorption peak at 1727 cm –1 , which relates to the hemicellulose’s C=O stretching. From the XRD studies, both crystalline and semi-crystalline zones may be seen in the diffractogram curves of OPEFB cellulose. Neosartorya sp. BCC 18065 produced more xylanase (92 ± 0.03 IU/g) on pretreated OPEFB compared to untreated OPEFB (61 ± 0.01 IU/g). With more xylanase enzymes present during fermentation, xylose production was enhanced. The results demonstrate that structural changes in OPEFB can be changed by PAA-assisted ultrasonication pretreatment, which also improves enzymatic hydrolysis and saccharification.","PeriodicalId":16613,"journal":{"name":"Journal of Oil Palm Research","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135804930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
