Enzymatic Hydrolysis of Lignocellulose for Bioethanol Production
2017
Abstract The effect of temperature, time and amount of enzyme on hydrolysis of wheat straw lignocellulose remaining after furfural production was studied. The residual substrate was subjected to enzymatic hydrolysis at different temperatures — 45 °C, 50 °C and 55 °C. Hydrolysis time was 72 hours, and samples were taken every 24 hours. The maximum glucose yield (76.5% of the theoretically possible) was reached when hydrolysis temperature 50 °C was used. The production rate of glucose increased with a hydrolysis period of time. The yield of glucose significantly depended on the ratio of enzyme to substrate.
Kinerja Sapi Bali Jantan yang diberikan pakan Rumput Gajah (Punnisetum purpureum) subtitusi fermentasi Jerami Padi
2018
The research was aimed to study Bali bulls fed with Pennisetum purpureum with fermented rice straws substitution in Manokwari Regency, West Papua was conducted experimentally with 12 Bali bulls that have average weight of 176.02±38.35 kg with 2 – 2,5 years old for 5 months duration. The study was designed using complete randomized design of nested pattern with 3 (three) treatments, 4 (four) replications and 4 (four) times weighing, with an assumption that Bali bulls are nested during weighing time. The results of this study showed that Penicetum purpureum substitution with fermented straws did not significant on Bali bulls body weight. The duration of fermented rice straws feeding that subs…
Highly sensitive monoclonal antibody-based immunoassays for boscalid analysis in strawberries
2018
Boscalid is an agrochemical recently developed for crop protection and the most significant member of the succinate dehydrogenase inhibitor group of fungicides. In this study, a collection of high-affinity monoclonal antibodies was generated to boscalid. By using a series of haptens with a linker at alternative tethering sites of the boscalid framework, specific antibodies were isolated as well as antibodies that also recognized the main boscalid metabolite. Two immunoassays were developed using different ELISA formats. Optimized assays displayed very high sensitivities (limits of detection were near 0.01 µg/L). Trueness and precision for the determination of the target analyte in strawberr…
The COMPASS experiment at CERN
2007
The COMPASS experiment makes use of the CERN SPS high-intensitymuon and hadron beams for the investigation of the nucleon spin structure and the spectroscopy of hadrons. One or more outgoing particles are detected in coincidence with the incoming muon or hadron. A large polarized target inside a superconducting solenoid is used for the measurements with the muon beam. Outgoing particles are detected by a two-stage, large angle and large momentum range spectrometer. The setup is built using several types of tracking detectors, according to the expected incident rate, required space resolution and the solid angle to be covered. Particle identification is achieved using a RICH counter and both…

STUDI ADSORPSI ION Pb2+ MENGGUNAKAN JERAMI PADI OLAHAN ASAL MANOKWARI
2008
<p><em>The waste material of agriculture such as the straw of rice was not yet used maximal as the kind of the materials for solution of environment pollution problem. Until this moment, there was any kind of ways that was done for separated the heavy metal from waste water, include the physical, chemistry and biology methods. Study of ion Pb<sup>2+</sup> absorption using treated rice straw was carried out to determine the absorption of heavy metal from water. The result shows absorption of heavy Cr<sup>3+</sup> &gt; Pb<sup>2+</sup> &gt; Cu<sup>2+</sup>. The absorption interaction between Pb2+ ion and treated straw shows La…
Reduction of Nitrates in Waste Water through the Valorization of Rice Straw: LIFE LIBERNITRATE Project
2018
An improved and more sustainable waste management system is required for successful development of technologies based on renewable sources. Rice straw is submitted to controlled combustion reactions and the produced ashes are chemically treated to produce silica. After a chemical activation step, the activated silica shows potential as an adsorbent agent and will be used to remove the excess of nitrates in groundwater and wells in the area of Alginet (Valencia, Spain), selected as a vulnerable zone within the Nitrates Directive. The demonstration activity aims to have a local impact on municipalities of 200 inhabitants or fewer, decreasing from current nitrate concentrations close to 50 mg/…
Microbial production of biopolymers from the renewable resource wheat straw.
2014
Aims Production of poly-s-hydroxybutyrate (PHB) and the chemical basic compound lactate from the agricultural crop ‘wheat straw’ as a renewable carbon resource. Methods and Results A thermal pressure hydrolysis procedure for the breakdown of wheat straw was applied. By this means, the wheat straw was converted into a partially solubilized hemicellulosic fraction, consisting of sugar monomers, and an insoluble cellulosic fraction, containing cellulose, lignin and a small portion of hemicellulose. The insoluble cellulosic fraction was further hydrolysed by commercial enzymes in monomers. The production of PHB from the sugar monomers originating from hemicellulose or cellulose was achieved by …
