Enhancing awareness of personal cleanliness and antibacterial resistance has intensified the substance request on consumable products. Antibacterial agents that have been commercialized nowadays are produced from inorganic non-renewable substances. This provides several drawbacks, particularly against health environmental issues. Therefore, many scientists work substituting fossil-fuel-based with natural ones such as biomass. Biomass derivatives, abundances biopolymers in world, amount to...
The efficient isolation process and understanding of lignin properties are essential to determine key features insights for more effective valorization as a renewable feedstock the production bio-based chemicals including wood adhesives. This study successfully used dilute acid precipitation recover from black liquor (BL) through single-step ethanol-fractionated-step, with recovery ~35% ~16%, respectively. physical characteristics lignin, i.e., its morphological structure, were evaluated by...
Extensive sample preparation procedures are required to analyze natural organic matter (NOM) in soil and sediment samples due the mineral matrix. The procedure not only requires a large amount of (typically more than 50 mg), but NOM extraction is frequently incomplete. In this study, 2–5 μg solid or 500 unprocessed were fixed on metal plate using double-sided adhesive tape analyzed directly laser desorption ionization (LDI) ultrahigh resolution mass spectrometry (UHR-MS). Most peaks reported...
Developing an effective pretreatment for the conversion of lignocellulosic biomass to ethanol is important effort in reducing cost this process. Microwave-assisted considered a green technology that can effectively break down structures. The objective study was investigate most temperature microwave-assisted oxalic acid regarding structural characteristic changes oil palm empty fruit bunches (OPEFB) fibers. fibers were subjected at 160""200 °C with 2.5 minutes heating time and liquid solid...
Black liquor is obtained as a by-product of the pulping process, which used to convert biomass into pulp by removing lignin, hemicelluloses and other extractives from wood free cellulose fibers. Lignin represents major constituent in black liquor, with quantities varying 20% 30%, very low share for manufacturing value-added products, while rest mainly burned energy purposes, thus underestimating its great potential raw material. Therefore, it essential establish new isolation extraction...
Lignin and tannins are polyphenolic materials that have the potential as natural antibacterial agents in many applications. The properties of lignin vary depending on their chemical structure, such source plant, type solvent used, bacteria. To date, no one has reported effect plant tannin. This study aimed to determine from Acacia mangium crassicarpa different solvents Each tannin dissolved five solvents: DMSO, NaOH, ethanol, water, ammonia. Antimicrobial analysis was done by agar well...
The pseudostem of banana (Musa sp.) has a high value for fiber. In this study, we characterized two wild Musa acuminata, i.e., ssp. malaccensis (LIPI-030) (M1) and var. breviformis (LIPI-218) (M3), an accession diploid M. acuminata cultivar "Pisang Rejang" (LIPI-048) (M2) one balbisiana Klutuk" (LIPI-054) (M4) its chemical (including Syringyl (S) Guaiacyl (G) ratio) physical mechanical properties, fiber analysis, morphological functional groups, crystallinity, thermal analysis. As result,...
Abstract The halal food industries are rapidly expanding to fulfill global demands. Non-halal substances such as porcine proteins often added intentionally or unintentionally products. development of highly selective and sensitive analytical tools is necessary, liquid chromatography–mass spectrometry a powerful tool that can cope with the challenge. LC–MS method has great potential for authentication, because it high sensitivity low detection limit detects several species markers different...
Kraft pulping of sweet sorghum bagasse (SSB) has been used for effective delignification method cellulose production. This study was conducted to evaluate the performance pulp kraft SSB reducing sugar The intended investigate effect active alkali and sulfidity loading variation on yield per biomass. prepared after using three variations (17, 19, 22%) (20, 22, 24%) at 170°C 4 h with liquor wood ratio 10. A total 9 pulps were obtained from these pretreatments. Delignification pretreatment...
