Over the last decades, microalgal biomass has gained a significant role in the development of different high-end (nutraceuticals, colorants, food supplements, and pharmaceuticals) and lowend products (biodiesel, bioethanol, and biogas) due to its rapid growth and high carbon-fixing efficiency. Therefore, microalgae are considered a useful and sustainable resource to attain energy security while reducing our current reliance on fossil fuels. From the technologies available for obtaining biofuels using microalgae biomass, thermochemical processes (pyrolysis, Hydrothermal Liquefaction (HTL), gasification) have proven to be processed with higher viability, because they use all biomass. However, due to the complex structure of the biomass (lipids, carbohydrates, and proteins), the obtained biofuels from direct thermochemical conversion have large amounts of heteroatoms (oxygen, nitrogen, and sulfur). As a solution, catalyst-based processes have emerged as a sustainable solution for the increase in biocrude production. This paper’s objective is to present a comprehensive review of recent developments on the catalyst-mediated conversion of algal biomass. Special attention will be given to operating conditions, strains evaluated, and challenges for the optimal yield of algal-based biofuels through pyrolysis and HTL.

Polyphenols are molecules with antioxidant potential for several diseases. In this research, an analysis of polyphenols production costs from Theobroma cacao L suspension cell culture was evaluated. The latter proposing different scenarios based on a large-scale plant production using the SuperPro Designer software. Two strategies for bioprocess improvement were proposed based on information from a traditional suspension cell culture (Strategy I). These improvements are firstly based on adding elicitors (Strategy II) for increasing polyphenol production and secondly, energetic use of cane bagasse and rice bran (Strategy III) by adding a gasifier. Results showed that the percentage of losses decreases from 19 % to only 5.8 % applying a recirculation system in losses lines product regarding Strategy II. Also, adding Methyl Jasmonate (MJ) elicitor increased the Y p / s yield up to 0.08 kg polyphenols/kg glucose. Gasification proposed in Strategy III achieved supplying 37 % of energy requirements using only 1.14 % of bagasse. One essential finding refers to the decreased cost of producing a 100 mg tablet formulated at 50 % of the active substance. Therefore, the latter resulted in 0.23 USD / tablet: promising data compared to 1.0-2.0 USD / tablet corresponding to the average value in the market. Thus, this research demonstrates that the increase of polyphenols by adding elicitors positively influences the operating costs.
