The recently isolated bacteria, Lysinibacillus sphaericus facultative anaerobe can digest lignin. objective of this study was to determine if the addition L. and MnSO4 could aid bioconversion OPEFB, enhance methane production during subsequent anaerobic digestion (AD). untreated OPEFB had specific potential 0.099 L/g VS doubled following pre-treatment with sphaericus. In...

Globally, bioenergy development depends on the efficacy and affordability of conversion technologies availability renewable biomass sources. As a tropical country, Indonesia has wide range sources, either from land or marine (i.e. macroalgae). The current estimation macroalgae potential in is estimated at approximately 9.96 million tonnes about 26.86% share world production 2021. Specifically, (wild cultivated) have received attention for their as resources sustainable production, supporting...

Bacterial nanocellulose (BNC), a biopolymer with exceptional physicochemical properties, has transformative potential in sustainable material applications. This study investigated the impact of sugar type (glucose, fructose, sucrose) and concentration (1%, 2%, 3% w/v) on BNC production by Komagataeibacter saccharivorans using sapodilla ( Manilkara zapota ) as substrate. Employing factorial randomized block design, assessed yield, pH variations, residual levels, structural properties Fourier...

Limbah tandan kosong kelapa sawit (TKKS) merupakan biomassa lignoselulosa yang terdiri dari lignin, selulosa, dan hemiselulosa, dapat dimanfaatkan lebih lanjut menjadi produk bernilai tinggi. Namun, diperlukan degradasi karena bersifat rekalsitran. Proses memanfaatkan kinerja jamur pelapuk coklat, dalam hal ini Serpula lacrymans, memiliki kemampuan berdasakan pembentukan radikal oksidatif pada pelapukan kayu. Oleh itu optimasi faktor mendukung proses selama inkubasi oleh lacrymans sawit....

Abstract The efficient utilization of all the key lignocellulosic biomass residues is important for development an integrated biorefineries uassing this as its feedstock. In study, a process involving simultaneous pre-treatement with anaerobic digestion (AD) were implemented processing oil palm empty fruit bunches (OPEFB) in order to produced both vanillin and methane. Before after treatment dry rot fungus ( Serpula lacrymans) was analyzed total reducing sugar (TRS), soluble phenols (TSP),...

Value-added chemicals, including phenolic compounds, can be generated through lignocellulosic biomass conversion via either biological or chemical pretreatment. Currently vanillin is one of the most valuable these products that has been shown to extractable on an industrial scale. This study demonstrates potential using rice straw inoculated with Serpula lacrymans, which produced a mixture high value bio-based compounds vanillin. Key extraction conditions were identified volume solvent used...

Putative iron-reductase (IR) genes from Serpula lacrymans with similarity to the conserved iron-binding domains of cellobiose dehydrogenase (CDH) enzymes have been identified. These were cloned and expressed functionally characterize their activity role in decomposition lignocellulose. The results show that IR1 IR2 recombinant ability depolymerize both lignin cellulose, are capable reduction ferric iron ferrous form, degradation nitrated lignin. Expression these during wheat straw...

Abstract Agro‐industrial residues, such as surplus fruits and vegetables are increasingly recognized valuable sources for isolating bacterial strains capable of efficiently producing nanocellulose (BNC). This study presents a novel approach to BNC production using Komagataeibacter intermedius SB 110 isolated from rotten pineapple, cultivated in sustainable medium coconut water enriched with 5% sucrose 0.5% pineapple peel extract. By leveraging agricultural waste, this method accelerates...

Abstract Fruit and vegetable wastes (FVW) are generated in many traditional markets Indonesia mostly disposed directly to landfill. Various studies highlighted that FVW could be further valorised either as bioenergy resources or other high-value products. In this study, the biochemical methane potential (BMP) its electrical energy from co-digestion of with macro-algae (MA), chicken manure (CM) tofu dregs (TD) were investigated. The research design used was a Completely Randomised Design...

Aims The effects of combinatorial stress on lipid production in Phanerochaete chrysosporium remain understudied. This species white-rot fungi was cultivated solid-state media while under variable levels known abiotic and biotic stressors to establish the effect upon fungal oil profiles. Methods Results Environmental induced fungus included following: temperature, nutrient limitation interspecies competition assess impact Fatty acid type its concentration were determined using analytical...

Abstract Indonesia experiences an increasing demand for energy, triggering the development of renewable particularly from biomass resources. Empty fruit oil palm bunches (EFOB) residue is one potential lignocellulosic highly abundant further application in bioenergy generation such as biogas. This study was aimed to investigate and evaluate EFOB biogas production using anaerobic digestion (AD) route. The AD investigated a batch experiment operated at inoculum substrate ratio (R I/S ) 6:1 30...

Abstract High consumption of fossil fuels in Indonesia needs to be reduced by using renewable energy, such as from biomass. In Indonesia, one the largest maritime countries, macroalgae (i.e. seaweed) are also considered potential biomass feedstocks for substituting any land This study aimed investigate biodegradability and biogas ( Gracilaria sp.) single-or co-digestion feedstock anaerobic digestion technology. The biochemical methane (BMP) test was carried out 28 days at temperature 37 °C...
