“…As hypothesized Bubble Farming© technique would grow microalgae without requirement of any post nutrient feeding in a totally sealed bubble (Gordon et al, 2019b). To check if this works, at rst it was necessary to select bubble wrap/s which allowed e cient exchange of gases, especially CO 2 and O 2 .…”

“…On the other hand, if diatoms are cultured in open systems the chances of contamination with spores, bacteria, fungi and other microalgae are very high (Xiang et al, 2017). As a solution, the possibilty of Bubble Farming© (Gordon et al, 2019a) stemmed out of earlier research on diatom solar panels for biofuel production (Gautam et al, 2016;Ghobara et al, 2019;Gupta et al, 2018;Kumar et al, 2016;Kumar et al, 2018;Vinayak et al, 2014).…”

“…However, these techniques have not succeeded at the commercial level due to the expensive cost of production of lipids which includes the nancial expenses in photobioreactors being $3.36/liter for PBR and $8. 35/liter for open ponds (Gordon et al, 2019a;Richardson et al, 2012;Singh et al, 2016). Offsetting these costs, increasing demand for crude oil has attracted biofuel from algae as one of the major alternative sources for liquid fuel (Ho et al, 2014;Leite et al, 2013).…”

The idea of culturing algae in closed systems by sealing the reactor rim tightly with plastic bubble wraps material is being used here to harvest DiafuelTM (Biofuel from diatoms). In this manuscript, microalgae such as diatoms are grown in flask PBR sealed with bubble wrap material of low density, high density and normal polyethylenes and compared to control flask PBR which is kept open. It was observed that low density polyethylenes (LDPE) bubble wrap sealed PBR harvested maximum Diafuel TM (37%), lipid (35 µgmL -1 ), had highest cell count (1152 x 10 2 cells mL -1), 0% water loss, 0% nutrient uptake and maximum CO2 absorbance (0.084) due to its permeability to gases until the 40th day compared to other plastic bubble wraps. The LDPE bubble wrap was therefore tested on green microalgae Haematococcus which showed coherent results and can be upscaled for astaxanthin production.

“…The single-celled photoautotrophic microorganisms—diatoms (Bacillariophyceae)—have an astonishing variety of intricately ornamented siliceous exoskeletons, called frustules or valves, with a unique three-dimensional structure ( Figure 1 [ 4 ]) in more than 100,000 known species [ 5 ]. Such a variety of unique, precise siliceous structures with orderly pore (areola) systems makes them a desirable material for modern technologies [ 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 ].…”

“Outsourcing” Diatoms in Fabrication of Metal-Doped 3D Biosilica

Diatoms have an ability that is unique among the unicellular photoautotrophic organisms to synthesize an intricately ornamented siliceous (biosilica) exoskeleton with an ordered, hierarchical, three-dimensional structure on a micro- to nanoscale. The unique morphological, structural, mechanical, transport, photonic, and optoelectronic properties of diatomaceous biosilica make it a desirable material for modern technologies. This review presents a summary and discussion of published research on the metabolic insertion of chemical elements with specific functional activity into diatomaceous biosilica. Included in the review is research on innovation in methods of synthesis of a new generation of functional siliceous materials, where the synthesis process is “outsourced” to intelligent microorganisms, referred to here as microtechnologists, by providing them with appropriate conditions and reagents.
