“…The main peak temperatures in the DTG curves (330 °C and 274 °C for Sp and Sp.N.W, respectively) suggest protein decomposition, which is the main nutrient of the Spirulina biomass, and also the thermal degradation of lipids and carbohydrates, as reported by Jamilatun et al [57]. Residual char levels of 27.95 ± 2.27% and 40.45 ± 0.51% were obtained for Sp and Sp.N.W, respectively.…”

“…In the case of the washed Spirulina biomass, the curves obtained did not present a clean base line as happened with Sp.N.W, so some small thermal transitions could have occurred; the main peak took place in this case at 158.6 ± 4.7 °C. In contrast, Zeller et al obtained a peak denaturation for Spirulina quite earlier, with a maximum at about 100 °C and ending at The main peak temperatures in the DTG curves (330 • C and 274 • C for Sp and Sp.N.W, respectively) suggest protein decomposition, which is the main nutrient of the Spirulina biomass, and also the thermal degradation of lipids and carbohydrates, as reported by Jamilatun et al [57].

The wide range of applications and the numerous advantages of plastics have led to their excessive use, with subsequent damage to ecosystems. As an environmentally friendly alternative, biocomposites have gained much attention, and microalgae have become a potential source for their production. In this study, the use of washed and unwashed Spirulina in polyethylene-based composites has been evaluated as a way to prevent the thermooxidation of polyethylene, while at the same time, reducing the amount of virgin plastic used. Biocomposites were produced by rotomolding, testing different biomass contents and determining their mechanical and thermal performances as well as their water uptake level. Composites with up to 15% of biomass (by weight), a particularly high ratio for rotomolding, were satisfactorily produced. Using 5% of both biomasses did not significantly modify the behavior when compared with the neat PE samples’ properties. For higher loadings, the use of non-washed biomass allowed us to obtain better properties, with added benefits related to using an unwashed biomass (less water consumption, lower costs and fewer environmental impacts). On the other hand, this study showed a promising beneficial effect on the thermooxidative resistance of composites, as the oxidation induction times were notably increased with biomass addition.

“…Likewise, bio-oil quality can be evaluated based on the functional groups in bio-oil and the content of oxygenated and aromatic compounds before and after the pyrolysis process. The lower the range of oxygenate compounds and the higher the content of aromatic compounds, the better the quality of the bio-oil [66]. Compared to commercial fuels (diesel and gasoline), oil palm shell bio-oil has a higher O/C content.…”

“…Arthrospira platensis is a prokaryotic photoautotrophic cyanobacterium characterized by high levels of lipids that are currently being used as a fuel source (Jamilatun et al, 2019;Sukarni et al, 2019;Jamilatun et al, 2020). Its biomass also contains protein and other valuable substances, so A. platensis is now also cultivated to market it as complete biomass.…”

The objective of this research was to develop a mathematical model for batch photoautotrophic cultivation of Arthrospira platensis and to validate it against data obtained in experiments. All trials were carried at 30°C, under a light intensity of 60 or 120 µmol m -2 s -1 . The purpose of the model was to determine the optimal concentration of carbon dioxide, as well as to investigate the formation of phycocyanin. For the experimental conditions in this study, the optimal concentration carbon dioxide (0.8% CO2, v/v) was predicted using the model according to the initial bicarbonate level, the carbon uptake by the microalga, the pH, and the mass transfer process. The use of this optimal value in the gas inlet seems to be a suitable option for maintaining the optimal pH (9.5), thereby eliminating the need for a pH controller in the bioreactor system. According to the simulations, the mass fraction of the phycocyanin formation rate seems to depend on the internal light level. The percentage of adjustment obtained (R 2 ) was ≥75%. The velocity of phycocyanin formation was enhanced at intensities up to 120 µmol m -2 s -1 . However, the actual internal irradiance values were lower than the light compensation point (4.5 µmol m -2 s -1 ), so phycocyanin formation ceased. The mathematical model may facilitate the examination of optimal carbon delivery, as well as the light input, in several A. platensis culture conditions aimed at phycocyanin production.
