Photobiomodulation (PBM), commonly known as red-light therapy, involves theexposure of light onto tissues for increased cellular activity. Examples of PBM include light-induced stimulation of damaged tissue, reduced inflammation, and increased metabolic activity(De Freitas, F.L, Hamblin, R.M. 2017). Past research proposes that light stimulation ofmitochondria yields increased ATP production when supplemented with photosynthetic pigmentsand light. Other studies have suggested the uptake of photosynthetic pigments into mammaliantissues as a mechanism for increased light harvesting. While PBM therapy is still underinvestigation, similarities between energy harvesting in photobiomodulation and photosynthesisare proposed explanations for increased metabolic activity. Photosynthetic bacteria andeukaryotic mitochondria potentially have similar energy-harvesting mechanisms (Alberts, B. et.al. 2002.), thus supplementing a eukaryotic organism, such as yeast, with bacterial pigmentscould provide insights to improved cell repair in humans. This project focuses on isolatingbacterial pigments under various wavelengths and intensities of light to enhance yeast growth.Bacterial pigments were grown under white light and subsequently implemented into a culture ofyeast. The yeast were grown in front of a supercontinuum light source to observe light absorptionas a function of wavelength. The overarching hypothesis of this work is that supplementation ofyeast with bacterial pigments could expedite yeast growth rate through stimulation of theelectron transport chain and increased ATP production. The results could offer a greaterunderstanding of PBM therapy for possible noninvasive medical applications, improvements inhealing, and supplementation of photobiomodulation with bacterial pigments as a promisingavenue of medical research.
