Temporal changes in carboxylate content of ryegrass with stepwise change in nutrition [PDF]
A detailed scheme of carboxylate formation and retention by plant tissues as a result of ion uptake and utilization is given. By means of discontinuities in the supply with nutrient ions, carboxylate retention by the tissues of perennial ryegrass was ...

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...

Hydrodeoxygenation of fatty acid methyl ester in gas oil blend–NiMoS/alumina catalyst
Green Processing and Synthesis, 2018 Hydrotreating of 10% fatty acid methyl ester (FAME) blended in gas oil was carried out by an NiMo-S/alumina catalyst and performed at an elevated temperature (300–400°C), a space velocity of 0.7–1.5 1/h and pressure 5 MPa.

Pd-catalyzed decarboxylative Heck vinylation of 2-nitrobenzoates in the presence of CuF2
Beilstein Journal of Organic Chemistry, 2010 A new protocol for the decarboxylative Heck vinylation of benzoic acids is disclosed. In the presence of a catalyst system generated in situ from Pd(OAc)2 (2 mol %), CuF2 (2 equiv), and benzoquinone (0.5 equiv) in NMP, a wide range of olefins were ...

Biofuels, Bioproducts and Biorefining, EarlyView.Abstract Post‐harvest agricultural residues in Latin America are commonly underutilized, leading to greenhouse gas emissions and lost opportunities for bio‐based value creation. This study tests the hypothesis that decentralized, farmer‐scale pyrolysis technologies can deliver comparable agronomic benefits while exhibiting distinct techno‐economic and ...

Genetically Programmed Control of Overflow Metabolism
Biotechnology and Bioengineering, EarlyView.ABSTRACT Overflow metabolism is a highly undesirable phenomenon that occurs in virtually all cell factories. Although several schemes have been applied to avoid overflow metabolism, this problem remains far from being solved. In this study, a genetic sensor for detecting overflow metabolism was designed, and its substrate specificity and reversibility ...
