Abstract The conversion of lignocellulosic biomass into bioethanol or biochemical products requires a crucial pretreatment process to breakdown the recalcitrant lignin structure. This research focuses on isolation and characterization lignin-degrading bacterial strain from decaying oil palm empty fruit bunch (OPEFB). isolated strain, identified as S treptomyces sp. S6, grew in minimal medium with Kraft (KL) sole carbon source. Several known ligninolytic enzyme assays were performed,...
The public widely uses Paracetamol (PCT) as an analgesic drug to reduce pain and fever symptoms in the human body. COVID-19 pandemic has led increase PCT consumption, resulting its presence water bodies establishing it a common aquatic environmental pollutant. Conventional methods for removal rely on chemical treatments, which necessitate harsh reaction conditions incur high operational costs. This study aims investigate potential degradation within anode environment of Microbial Fuel Cell...
In this work, a new thermostable and organic solvent-tolerant lipase produced from Rhizopus sp. strain PKC12B2 was characterized to evaluate its activity stability toward pH, temperature, solvents, surfactants. The catalytic efficiency of the enzyme also analyzed through kinetics study. Produced exhibits remarkable at pH 8.0 10.0 shows optimum 9.0, demonstrating alkali properties. Lipase has an temperature 45 oC possesses significant thermal in range between 55 oC. Exceptional demonstrated...
This study investigates the design of a stirred batch reactor with scale-up for degumming crude palm oil (CPO) using phosphoric acid (H3PO4). Laboratory-scale experiments were conducted in triple-neck round vessel, followed by to larger-scale flat-bottom tank reactor. Traditional methods geometric similarity criteria are ineffective reactors different geometries; hence, this work introduces an improved approach efficiency, measured gum concentration, as criterion Computational Fluid Dynamics...
We report the draft genome sequence of Agrobacterium sp. strain S2, isolated from a decaying oil palm empty fruit bunch (OPEFB) in Negeri Sembilan, Malaysia, which yields potential genes encoding lignin degradation enzymes. This 9,722,071 bp exhibited 58.9% GC content, 10,416 coding genes, and 12 RNAs.
Electronic waste has been the fastest increasing generated globally and is predicted to surpass 111 million tons per year by 2050. This trend concerning, not just due growing volume but also its high composition of heavy metal elements, leading potential environmental pollution if managed properly. However, this issue opens a new prospect in material acquisition through concept urban mining via extraction from electronic waste. A conventional method extraction, i.e., chemical leaching,...
<p><strong>Abstract.</strong>The surge in mask consumption during the COVID-19 pandemic led to widespread use of disposable polypropylene masks for protection. However, accumulation used poses environmental challenges due slow degradation polypropylene. Here, we investigate potential <em>Tenebrio molitor</em> larvae degrading masks, exploiting their synthetic polymer-breaking enzymes and associated microflora. In this study, implemented various feeding...
Due to the increased usage of tires, accumulation worn tires has become a significant environmental concern and necessitates environmentally friendly waste management strategies. Conventional methods, such as tire incineration or improper disposal, contribute degradation. It is reported that organisms, Tenebrio molitor larvae, can degrade wide range polymers. This study explores promising potential larvae in addressing this concern. Through series experiments, were fed with cut-worn...
The conversion of lignocellulosic biomass into bioethanol or biochemical products requires a crucial pre-treatment process to break down the recalcitrant lignin structure. Biological depolymerization using microbial enzyme appeared be promising alternative as it offers environmentally friendly treatment with lower energy requirements. In this study, three (3) thermophilic bacterial strains (S2, S11Y, S23) lignin-degrading potential were previously isolated from palm oil wastes and identified...
Streptomyces spp. are bacteria that responsible for the degradation of aromatic compounds and produce secondary metabolites. Here, we present a complete genome sequence sp. strain S6, which was isolated from an oil palm plantation, with 7.8-Mbp liner chromosome, GC content 72%, 4,266 coding sequences.
Biological pretreatment using microbial enzymes appears to be the most promising pre-treatment technology for breakdown of recalcitrant lignin structure. This research focuses on identification and characterization lignin-depolymerizing in Bacillus subtilis strain S11Y, previously isolated from palm oil wastes Malaysia. The draft genome sequences this highly revealed that lacked any well-known dye-decolorizing peroxidase or catalase-peroxidase are commonly reported involved depolymerization...
Nanomaterials have made significant advancements in various applications, particularly the field of catalysis. The limited lifespan nickel-based catalysts due to sintering at high temperatures has presented a challenge that requires innovative solutions.
