Case Study

Study on the Degradation of Hexadecane by Pseudomonas Aeruginosa

Solyanikova, I. P., et al. Microbiology, 2019, 88, 15-26.

Environmental pollution caused by refined products and petroleum components is one of the most challenging problems. Since hexadecane is one of the components of petroleum, the study of hexadecane degradation is crucial. In this study, hexadecane was used as a model compound to study the interaction between microbial cells and hydrophobic compounds.
The diagram illustrates the hexadecane degradation pathway of Pseudomonas aeruginosa strain IASST201, which shows the highest bioflocculant-synthesis activity among 34 tested growth substrates when cultivated on hexadecane.
The bioflocculant produced by P. aeruginosa strain IASST201 from hexadecane was evaluated for its heavy metal extraction capabilities. Composed of hydrocarbon monomers and protein in a ratio of 89.4% to 6.2%, this bioflocculant successfully removed heavy metal ions (Ni2+, Zn2+, Cd2+, Cu2+, and Pb2+) from aqueous solutions with concentrations ranging from 1 to 50 mg/L. The maximum removal efficiency of the bioflocculant, measured at 79.29 ± 0.12%, was achieved for Ni2+.

Study on Subcooling in Hexadecane Phase Change Material Emulsion

Günther, E., et al. International journal of refrigeration, 2010, 33(8), 1605-1611.

In this work, hexadecane (a simple linear alkane that is generally considered an "easy PCM") was selected as the phase change material (PCM) and emulsions with different droplet size distributions were prepared to study the supercooling behavior of PCM.
· Hexadecane Emulsion Sample Preparation
This study utilized hexadecane-water emulsions as a sample system. The size of the Phase Change Material (PCM) was altered, with droplet sizes ranging from 200 μm to 20 mm when examined in a non-emulsified state. To stabilize the emulsions, two different surfactants were employed to investigate any surfactant-related effects alongside the anticipated impact of droplet size.
· Key Findings
Experimental results showed a connection between droplet size and subcooling in hexadecane which resulted in emulsion subcooling levels ranging from 5 K to 15 K together with evidence that surfactants significantly change thermal properties through surface effects that affect solidification. This research highlighted that an increased surface-to-volume ratio, which enhances heat transfer, can lead to unexpected and sometimes undesirable consequences, even in simple materials like hexadecane.
