NºPublicación: US2018195032A1 12/07/2018

Solicitante:
NELSON MANDELA UNIV [ZA]

Resumen de: US2018195032A1

Microalgae cultivation equipment for the cultivation of microalgae is provided in which a raceway is modified so as to contain multiple generally upright photobioreactor columns spaced apart along its length so as to increase the total surface area of liquid growth medium directly exposed to light and to improve the transfer of CO2 from the gas-phase to the liquid-phase by providing adequate height inside the vertical photobioreactor columns. The lowermost ends of the photobioreactor columns are immersed inside the liquid growth medium in the raceway component and are fed with liquid growth medium by a circulation promoting facility circulating the liquid growth medium from the raceway through the photobioreactor columns to become discharged back into the raceway. Gas inlets provide CO2 containing gas bubbles passing upwards in each of the photobioreactor columns. One or more paddle wheels or jet pumps induce a flow of liquid growth medium within the raceway.

Productivity and Bioproduct Formation in Phototropin Knock/Out Mutants in Microalgae

NºPublicación: US2018187170A1 05/07/2018

Solicitante:
NMC INC [US]
LOS ALAMOS NAT SECURITY LLC [US]

Resumen de: US2018187170A1

Phototropin is a blue light receptor, which mediates a variety of blue-light elicited physiological processes in plants and algae. In higher plants these processes include phototropism, chloroplast movement and stomatal opening. In the green alga Chlamydomonas reinhardtii, phototropin plays a vital role in progression of the sexual life cycle and in the control of the eye spot size and light sensitivity Phototropin is also involved in blue-light mediated changes in the synthesis of chlorophylls, carotenoids, chlorophyll binding proteins. We compared the transcriptome of phototropin knock out (PHOT KO) mutant and wild-type parent to analyze differences in gene expression in high light grown cultures (500 μmol photons m−2 s−1). Our results indicate the up-regulation of genes involved in photosynthetic electron transport chain, carbon fixation pathway, starch, lipid, and cell cycle control genes. With respect to photosynthetic electron transport genes, genes encoding proteins of the cytochrome b6f and ATP synthase complex were up regulated potentially facilitating proton-coupled electron transfer. In addition genes involved in limiting steps in the Calvin cycle Ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO), Sidoheptulose 1,7 bisphosphatase (SBPase), Glyceraldehyde-3-phosphate dehydrogenase (3PGDH) and that mediate cell-cycle control (CDK) were also up regulated along with starch synthase and fatty acid biosynthesis genes involved in starch and lipid synthesis.
