The common carp, Cyprinus carpio, is one of the most important cyprinid species and globally accounts for 10% of freshwater aquaculture production. Here we present a draft genome of domesticated C. carpio (strain Songpu), whose current assembly contains 52,610 protein-coding genes and approximately 92.3% coverage of its paleotetraploidized genome (2n = 100). The latest round of whole-genome duplication has been estimated to have occurred approximately 8.2 million years ago. Genome resequencing of 33 representative individuals from worldwide populations demonstrates a single origin for C. carpio in 2 subspecies (C. carpio Haematopterus and C. carpio carpio). Integrative genomic and transcriptomic analyses were used to identify loci potentially associated with traits including scaling patterns and skin color. In combination with the high-resolution genetic map, the draft genome paves the way for better molecular studies and improved genome-assisted breeding of C. carpio and other closely related species.

Upgrading of bio-oil over metal/zeolite bi-functional catalysts, is of high necessity and popularity in converting biomass to high-quality hydrocarbons (transportation fuels and petrochemicals) to reduce the overall CO2 emissions of fossil based materials.

Electrochemical methods are potentially an energy-saving way to capture CO 2 from flue gas. Unlike the regeneration of amine through high-temperature thermal distillation in commercial CO 2 absorption processes, the CO 2 absorption solution is regenerated by electrolysis at a low temperature. In this work, tiron (disodium 4,5-dihydroxy-1,3benzenedisulfonate, QH 2 ) was employed as a pH mediator because its redox reactions can change the pH of the solution. Na 2 Q, which was prepared by QH 2 and NaOH in a molar ratio of 1:2, was used to capture CO 2 because of its alkalinity. Then, CO 2 was desorbed by the oxidation of QH − and QH 2 formed in the CO 2 -rich aqueous solution to quinone (Q) to release protons, and the alkalinity was recovered by the reduction of Q to the quinone dianion (Q 2− ). The redox performance of Na 2 Q in aqueous solution was investigated using cyclic voltammetry, and the CO 2 capacity of Na 2 Q solutions at different concentrations (0.1−0.7 M) was measured. The results show that the redox behavior of Na 2 Q was reversible in the neutral or weakly alkaline solutions. However, the reduction of Q to Q 2− by electrolysis was difficult in a high pH solution. During adsorption, the Na 2 Q solution absorbed CO 2 at a molar ratio of about 1:1 (CO 2 /Q 2− ≈ 1). The CO 2 -saturated Na 2 Q solution was electrolyzed in the anode zone under a constant current. The CO 2 desorption rate reached 100%, and Q 2− , QH − , and QH 2 were oxidized to give Q. In the cathode zone, Q was reduced to Q 2− , which could be used to adsorb CO 2 from flue gas. On the basis of the potential difference between the cathode and anode, the regeneration energy consumption was estimated to be about 2.4 GJ/tonne of CO 2 .

Different biobased chemicals are produced during the conversion of biomass into fuels through various feasible technologies (e.g., hydrolysis, hydrothermal liquefaction, and pyrolysis). The challenge of transforming these biobased chemicals with high hydrophilicity is ascribed to the high water content of the feedstock and the inevitable formation of water. Therefore, aqueous-phase processing is an interesting technology for the heterogeneous catalytic conversion of biobased chemicals. Different reactions, such as dehydration, isomerization, aldol condensation, ketonization, and hydrogenation, are applied for the conversion of sugars, furfural/hydroxymethylfurfural, acids, phenolics, and so on over heterogeneous catalysts. The activity, stability, and reusability of the heterogeneous catalysts in water are summarized, and deactivation processes and several strategies are introduced to improve the stability of heterogeneous catalysts in the aqueous phase.

Amine-based CO 2 postcombustion capture is a commercialized technology for recovery CO 2 from flue gas, and the energy consumption is concentrated in the regenerative stage. The phase-change solvent system, monoethanolamine (MEA, absorbent) + solvent A (SA, solvent) + water (solvent), was investigated on the performances of CO 2 absorption and desorption. CO 2 -rich solvent can be continuously separated for the feeding flow of the regeneration tower; thereby, it significantly reduces the energy of regeneration. The results show that the solvent with suitable composition can easily separate the CO 2 -rich phase from the solvent, and the CO 2 -rich phase accounts for more than 98% of the total CO 2 . At 293−333 K, the temperature has no significant effect on the absorption rate and phase equilibrium. The estimation of energy consumption shows that the reboiler work can be reduced by 43.6% compared with that using 20 wt % MEA aqueous solution.

In this paper, Euglena sp. microalgae with low lipid and high ash contents were successfully converted into bio-oil with/without catalysts through hydrothermal liquefaction (HTL) at 280 °C and a reaction time of 30 min.

N 6 -methyladenosine (m 6 A) is considered as a reversible RNA modification occurring more frequently on the GAC than AAC context in vivo, which regulates post-transcriptional gene expression in mammalian cells. m 6 A 'writers' METTL3 and METTL14 demonstrate a strong preference for binding AC-containing motifs in living cells. However, this evidence is currently lacking for m 6 A erasers, leaving the dynamics of the internal m 6 A modification under debate recently. We analysed three recently published FTO CLIP-seq data sets and two generated in this study, one of the two known m 6 A 'erasers'. FTO binding peaks from all cell lines contain RRACH motifs. Only those from K562, 3T3-L1and HeLa cells were enriched in AC-containing motifs, while those from HEK293 were not. The exogenously overexpressed FTO effectively binds to m 6 A motif-containing RNA sites. FTO overexpression specifically removed m 6 A modification from GGACU and RRACU motifs in a concentration-dependent manner. These findings underline the dynamics of FTO in target selection, which is predicted to contribute to both the m 6 A dynamics and the FTO plasticity in biological functions and diseases.
