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

NºPublicación: US2020208125A1 02/07/2020

Solicitante:

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

Resumen de: US2020208125A1

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−2s−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.

NEW EXTERNAL LOOP "AIR-LIFT" BIOREACTOR FOR TREATING LIQUID EFFLUENT

NºPublicación: WO2020139067A1 02/07/2020

Solicitante:

UNIV SULTAN MOULAY SLIMANE BENI MELLAL [MA]

Resumen de: WO2020139067A1

An innovative method for biological treatment has proven to be very effective and less expensive for treating various soluble and colloidal pollutants in agricultural, industrial and urban liquid waste. The present invention relates to an industrial device that allows degradation of the organic pollutant load of effluent by biological processing. The technique has been successfully tested in the case of liquid waste with a high biological load. The treatment was carried out in the presence of microalgae. The depollution of the waste in the external loop air-lift bioreactor that has been developed occurs with a continuous supply of the waste that is to be treated and through the contribution of oxygenation, for the first time using ventilation in this type of apparatus. The invention is focused on administering a significant amount of ambient air containing the oxygen and carbon dioxide that is required for biological treatment in the presence of microalgae. This contribution is provided, for the first time in this type of reactor, through ventilation that allows a pressure differential to be created between the outside and the inside of the reactor, which allows a considerable air flow to be routed towards the inside of the apparatus. Compared to the other treatment techniques that are applied in similar reactors, the present method has proven to be highly advantageous in terms of the effectiveness of the treatment and of energy consumption.

Resumen de: WO2020130772A1

The invention relates to an inducible nuclear promoter isolated from the freshwater green microalgae Chlamydomonas reinhardtii (CrGPDH3 promoter), which was originally used to promote the expression of the CrGPDH3 gene which codes for the enzyme glycerol 3-phosphate dehydrogenase. The invention comprises a core promoter, a region of inducibility and chimeric promoters including said core promoter and the region of inducibility. The advantages of the present invention include the fact that it is a nuclear promoter, regulated by inducers which are easy to obtain and to apply, with low toxicity and low cost, such as NaCl. This promoter represents an alternative for the regulation of gene expression in photosynthetic organisms and it is useful for heterologous gene expression for the purpose of basic research or for biotechnological purposes, such as the production of recombinant proteins.
