Investigating the molecular basis of vitamin B12 uptake in Chlamydomonas reinhardtii
… is Cobalamin Acquisition Protein 1 (CBA1) - identified in the diatoms Phaeodactylum tricornutum and Thalassiosira pseudonana - which was found to increase the B12 uptake rate when overexpressed. However, no proteins required for B12 uptake have been identified in green algae. In this …

Insights into vitamin B₁₂ production, acquisition, and use by marine microbes
… to identify a novel B₁₂ acquisition protein, CBA1, in diatoms. This represents the first identification of a B₁₂ acquisition protein in eukaryotic phytoplankton. Transcripts encoding CBA 1 were detected in natural phytoplankton communities, confirming that B₁₂ acquisition is an important part …

Molecular biology of B vitamin metabolism genes and their regulation in Phaeodactylum tricornutum
… and the Cobalamin Acquisition Protein 1 (CBA1) knock-out confirmed it is necessary for cobalamin uptake. Taken together, the results in this thesis provide new insights into thiamine and cobalamin metabolism, transport and genetic regulation in diatoms. Unexpected results such as the …

Investigating the provision of vitamin B₁₂ in the Micro-Ecological Life Support System Alternative (MELiSSA) loop for long-distance space exploration using algal-bacterial cocultures.
… to show that Cobalamin Acquisition Protein 1 (CBA1) is necessary for the uptake of pseudocobalamin by *C. reinhardtii*. In addition, two species of edible microalgae, *Chlorella vulgaris* and *Haematococcus pluvialis* can accumulate both cobalamin and pseudocobalamin. Using *Lobomonas …

Effects of Fused Filament Fabrication Process Variables on Microstructural Alignment and Intra-layer Properties in PLLA
Extrusion-based 3D printing is commonly used to produce complex structures from thermoplastics. Conventional fused filament fabrication (FFF) is used widely and forms objects through layer-by-layer deposition. However, there is often a need for thin support structures based on single print layers, …
