Botryococcus braunii has garnered significant attention in recent years due to its ability produce high amounts of renewable hydrocarbons through photosynthesis. As the world shifts towards a greener future and seeks alternative sources energy, cultivation B. extraction can potentially provide viable solution. However, development sustainable cost-effective process for cultivating is not without challenges. Compared other microalgae, grows very slowly, making it time-consuming expensive biomass. In response these challenges, several efforts have been put into optimizing systems increase biomass growth hydrocarbon production efficiency. This review presents comparative analysis different systems, factors affecting productivity are critically discussed. Attached offers advantages, including higher less water requirement compared liquid culture. These advantages hold potential enhancing economic viability microalgal fuels. Here, we propose that employing attached cultivation, coupled with milking technique extraction, represents an efficient approach generating fuels from braunii. Nevertheless, further research needed ascertain large-scale implementation.

Coal, petroleum and natural gas have remained the premium energy sources driving economy sustaining population growth for years. Global human has shown a 7-fold increase in last two centuries and, consequently, an astronomical global demand. Interestingly, rising warming, climate change destruction of environment are trends parallel with world profile continual dependence on fossil fuels. Actions to mitigate these challenges ignited interest autotrophic production hydrocarbons from microalgae as alternative fossil-based The microalgal strain, Botryococcus braunii, offers excellent platform renewable production. B. braunii unusual fascinating attributes, by producing liquid extracellularly, classical non-invasive, non-destructive extraction technique known milking can be applied. In process, extracellular matrix algae repetitively extracted without need cell harvesting, dewatering, disruption, purification metabolites, thereby reducing downstream processing costs. this way, do not grow cellular biomass but act only light-driven catalysts convert CO2 into that accumulate externally medium. work, different lipid techniques discussed depth, taking critical analysis effect each process hydrocarbon recovery purity well their economic viability. Moreover, composition factors influencing is comprehensively reviewed. critically discussed, cultivation protocols suitable strategies improve highlighted. We indicate switchable solvent-based exceptional potential biofilm-based holds great promise reduce However, more research needed large-scale implementation feasibility.

Membrane fouling is a major challenge which limits the sustainable application of membrane filtration-based microalgal harvesting at industrial level. leads to increased operational and maintenance costs represents obstacle downstream processing. Nano-clays are promising naturally occurring nanoparticles in fabrication due their low-cost, facile preparation, superior properties terms surface hydrophilicity, mechanical stability, resistance against chemicals. The modification using nano-clays approach improve membranes resistance. However, positive effects nano-clay particles on often limited by aggregation poor adhesion base polymeric matrix. This review surveys recent efforts achieve anti-fouling behavior with fillers. Further, strategies better incorporation polymer matrix summarised, factors that govern fouling, adhesion, agglomeration leaching discussed depth.

Anaerobic digestion of organic waste produces effluent (ADE) that requires further treatment. Biofilm-based microalgal cultivation is a favoured approach to ADE This study compared Chlorella sp. MUR 268 and Scenedesmus 269 in biofilm suspension cultures treat anaerobic digestate food (ADFE). had significantly higher biomass (50.38 g m−2) than (9.39 m−2). Conversely, yielded 1.5 times more (1.2 L−1) suspension. 49.3 % areal productivity suspension, while showed 87.3 growth removed nutrients ADFE. In COD, ammoniacal nitrogen, phosphate were reduced 94.9, 5.2, 5.98 mg L−1 for 268, 245, 2.89, 3.22 269, respectively. biofilm, achieved reductions 149.9, 1.16, 3.57 L−1, 100.2, 6.9 2.07 L−1. Most these values are below the recommended discharge standard, highlighting efficacy this system ADFE Biofilm fixed 68–81 nitrogen was biomass, only 55–71 ended biomass. 88 phosphorus, phosphorus (55 %) counterpart (34 %). design offers advantages like simplified, cost-effective operation, easy recovery, water usage.
