“…The Table (7 Depending on the practically validate Box-Behnken model, the synthesis of lipids from the F. oxysporum NRC 2017 wild type and mutants have been optimized. The model was validated under different variables for predicted lipid production maximum in comparison to the actual value, chosen value with a lower nitrogen source, and synthetic medium, as shown in the data in Figure (3). For F. oxysporum NRC 2017-1, the lipid-increasing rate was 28.09%.…”

“…It was predicted that growing markets and developing economies would account for over 70% of the projected world energy demand, which would result in a growth in GHG emissions [2]. Therefore, it is essential to evaluate the ability of these growth economies to create bioenergy that can sustainably replace fossil fuels as well as the effects of these activities on the environment [3]. A substitute for fossil fuel, users might use biodiesel in place of or combined with fossil diesel but has improved cetane number, lower sulfur, non-toxicity, biodegradability, low aromatic compounds, and other characteristics that reduce GHG emissions [4,5].…”

Background: Climate change is still a problem we face that has an impact on us every day even as our world develops technologically. Energy has been and will continue to be a key engine of economic growth. The greenhouse gas emissions (GHG) from biodiesel are less than those of fossil fuels. The objective was to improve biodiesel production from a fungus called Fusarium oxysporum NRC 2017 using the bagasse hydrolysate of Bacillus cereus 3SME as a cheap carbon source. Results: To enhance lipid accumulation in F. oxysporum NRC 2017, four mutagenic agents were used: gamma radiation (Ɣ ray); ethidium bromide (Et Br); ethyl methane sulfonate (EMS); and sodium azide (NaN3). Using the Inter-Simple Sequence Repeats (ISSR) as a molecular biomarker, the findings demonstrated a significant difference between the F. oxysporum NRC 2017 wild type and induced mutants examined. The culture conditions were optimized for F. oxysporum NRC 2017 and F. oxysporum NRC 2017-1, F. oxysporum NRC 2017-2, and F. oxysporum NRC 2017-3 using the response surface methodology (RSM) and the maximum lipid content (g/l) was 2.40, 3.47, 3.81, and 2.63, respectively. According to gas chromatography (GC) analysis, the biodiesel compositions produced from the F. oxysporum NRC 2017 wild type and its mutants exhibited generally C16-C18 and were suitable for biodiesel synthesis. F. oxysporum NRC 2017 and mutant biodiesels indicated physical features that were close to those of standard biodiesel. Conclusion: The biodiesels produced from the F. oxysporum NRC 2017 and its mutants could be used for large scale as eco-friendly products from a cheap carbon source.

“…Therefore, there is capacity for further production and utilization in Brazil. Argentina also holds a prominent position in biodiesel production within Latin America (Canabarro et al, 2023), producing approximately 2.2 million m 3 of biodiesel from soybean in 2022. Around 48% of this biodiesel was exported to Europe.…”

This Opinion highlights several successful cases of biofuel technologies recently described by the IEA Bioenergy Intertask Report on Lessons Learned. The report discussed the potential of biofuels to contribute to a significant market supply, thus replacing fossil fuels and mitigating global warming, and it underscores the challenges in expanding biofuel production and replicating successful models between countries and regions. Based on the lessons learned from conventional, established technologies, the authors analyzed policies, feedstocks, products, technologies, economics, environmental concerns, social aspects, scalability, and ease of implementation and replication in different countries or regions. There are blending mandates in place around the world to foster the use of biofuels. Dependence on the availability and price fluctuations of crop feedstocks may limit biofuel production in certain circumstances. Legal restrictions on using food crops as feedstocks present obstacles to scaling up production. Temporary constraints related to feedstock costs and availability, as evidenced by changes and postponements of biofuel blending mandates in various countries (particularly during the COVID‐19 pandemic) also pose challenges. Technological hurdles exist for advanced biofuels that implicate premium pricing. Still, 2G ethanol from sugarcane meets very strict feedstock requirements with a carbon footprint so low that only electric vehicles charged in Norway could have life‐cycle GHG emissions at the same level as a 2G ethanol‐fueled combustion engine car. The authors evaluate whether and how much electrification could contribute to advance the decarbonization efforts in different countries. Drawing from these observations, the authors express their viewpoints to assist researchers and policymakers in the energy sector in formulating viable approaches to combat the climate crisis.

“…Reduction in fuel reserves and rising environmental issues have increased the attention of researchers toward alternative fuels in place of conventional fuels. , To protect the environment, the search for green fuels to replace fossil fuels is necessary. , Biodiesel (the most attractive biofuel type) is the most potential alternative fuel for conventional diesel engines . Biodiesel can be used as a green fuel in engines in pure form or mixed with diesel in different ratios in compression combustion engines. , Transesterification of pure triglycerides, which are mainly found in expensive feedstocks such as vegetable oils, has been one of the most useful and widely used methods to produce biodiesel based on free fatty acids. − In recent years, many countries have emphasized and encouraged the use of alternative green fuels such as biodiesel fuel by governmental pathways by means of both incentives and prescriptive volumetric necessities .…”

Herein, we reported an efficient and novel metal−organic framework (MOF) that was designed and fabricated via hydrothermal reaction of chromium(III) nitrate nonahydrate salt with EDTA as an organic ligand. The prepared MOF was investigated by PXRD, BET, SEM, EDS, FT-IR, and X-ray mapping techniques. N 2 adsorption−desorption isotherms indicated excellent BET surface area for Cr-EDTA-MOF, which is 234.55 m 2 /g. The prepared Cr-EDTA-MOF exhibits efficient and potential performance for the esterification of oleic and palmitic acids under gentle reaction conditions. Furthermore, this nanostructure material afforded several benefits, including excellent product yields, stability, easy methodology, easy workup, and greener situations. Furthermore, this heterogeneous nanocatalyst (Cr-EDTA-MOF) could be easily recovered from the reaction mixture by centrifugation and reused for four consecutive runs with a minimum loss of catalytic activity.
