Special Issue Information

Dear Colleagues,

The increasing global demand for sustainable and renewable resources has catalyzed significant advancements in the field of biorefineries, with microalgae emerging as a potent source of bio-based products. Microalgae, known for their rapid growth rates and high biochemical productivity, offer a versatile platform for producing biofuels, pharmaceuticals, nutraceuticals, and other valuable biochemicals. This exploration encompasses the latest technological breakthroughs in cultivation, harvesting, and bioprocessing techniques, highlighting their roles in enhancing yield, efficiency, and economic viability. From advanced photobioreactors and genetic engineering to novel extraction methods and bioconversion processes, this Special Issue on "Advanced Technologies for the Production, Processing, and Extraction of Biorefinery Products from Microalgae" provides a comprehensive understanding of the state-of-the-art strategies employed to harness the full potential of microalgae in biorefineries. As we navigate the complexities of scaling these technologies for industrial applications, this Special Issue underscores the pivotal role of microalgae in the transition towards a sustainable bioeconomy.

Topics include, but are not limited to, the following:

  • Innovative Cultivation Techniques for Microalgae;
  • Advanced microalgae harvesting and Dewatering Methods;
  • Extraction of Biorefinery Products from Microalgae;
    Optimization of Microalgae Growth Conditions and Nutrient Supply;
  • Regulatory and Market Challenges in Algal Biorefinery Products;
  • Applications of Machine Learning and AI in Algal Biotechnology.

Commiphora gileadensis is a medicinal plant with a wide range of biological characteristics. Many medical diseases can be treated using the leaves of C. gileadensis, including bacterial infections, inflammatory illnesses, and wounds. As a result, the Soxhlet extraction method was used to extract the phenolic components and measure the recovery yields from C. gileadensis leaf. The impacts of the Soxhlet extraction parameters (extraction time 30–150 min, sample/solvent ratio 1:20–1:40 g/mL, and concentration of ethanol solvent 20–100% v/v) on the total flavonoid content (TFC), total phenolic content (TPC), and extraction yield were investigated using the one-factor-at-a-time (OFAT) technique. Fourier transform infrared spectroscopy (FTIR) and gas chromatography–mass spectroscopy (GC–MS) analyses have been employed to evaluate the extracts for the presence of various phytochemicals. According to the results, the C. gileadensis leafs ethanolic extract extracted via the Soxhlet process achieved the maximum yields at 90 min of extraction time, a feed/solvent ratio of 1:30 g/mL, and a 40% v/v ethanol concentration. These yields were: extraction yield = 23.20 ± 0.10% w/w, TPC = 59.93 ± 1.33 mg GAE/g d.w., and TFC = 19.65 ± 1.77 mg QE/g d.w.. Further, a total of 20 phenolic components with excellent antioxidant characteristics were found in the leaf extract of C. gileadensis extracted via the Soxhlet method. Full article
