Biochemical Pathways Regulated by Algae to Mitigate Global Carbon Emissions: A Review

Direct carbon capture for the production of high-performance biodegradable plastics by cyanobacterial cell factories

“…4C and E). In the 13 C NMR spectrum, carbonyl carbon (-OCO-), oxymethylene carbon (-OCH-), and methyl carbon (-CH 3 ) signals typically occur in the region of δ 170, δ 69, and δ 17, respectively, representing the configurational structure of PLA. This result shows that the product is the PLA polymer (Fig.…”

“…The composition of the polymer was determined by NMR on a Bruker AVANCE III HD 600 MHz (Bruker, Rheinstetten, Germany) using tetramethylsilane (TMS) as an internal stan-dard. The polymer was diluted in CDCl 3 and the NMR spectra were recorded at 298 k. The 1 H NMR spectrum was acquired using an excitation flip angle of 30°at the delay time of 10 s. In the 13 C NMR experiment, the 30°pulse width was 3.5 μs at the delay time of 2.5 s. The 2D COSY experiment was performed with 1.3 s delay time, 16 scans and processing data size of 2 k × 1 k.…”

“…Excessive CO 2 emissions aggravate global warming and climate change due to industrial activities and the continuous use of fossil fuels. 13 Meanwhile, CO 2 is also one of the most abundant natural carbon resources and has recently been recognized as the ideal feedstock for third-generation biorefineries. 5 Therefore, it would be wise to produce PLA directly from CO 2 .…”

Under Different Working Conditions Carbon Oxides and Nitrogen Oxides Emission of n-Butanol and LNG in Diesel Engine

“…Carbon dioxide (CO2), being an important greenhouse gas (GHG) significantly present in Earth's atmosphere, has been increasing because of several anthropogenic activities leading to global warming. [12] NOx is a major cause of smog, ground level ozone and also a cause of acid rain. The development of improved NOx reduction technologies is therefore of critical importance to the global environment.…”
