Visit of the Academy Council of the Czech Academy of Sciences at the ALGATECH Centre
On October 29, 2024, we had the honor of welcoming members of the Academy Council of the Czech Academy of Sciences to the ALGATECH Centre. Prof. Ing. Roman Sobotka, Ph.D., together with the heads of individual laboratories, presented the scientific focus of the centre, which covers phototrophic microorganisms, ranging from basic research on photosynthesis in bacteria to genome editing in cyanobacteria, and applied collaboration with companies in the development of downstream processes for valuable compounds from microalgae.
The new project "Photomachines" from the Jan Amos Komenský Operational Program, focused on synthetic biology and metabolic engineering, received significant attention. This research aims to contribute to the production of therapeutic peptides using microalgae.
Successfully completed
ALGATECH Centre - Inst. Microbiol. Czech Acad. Sci. (IMIC) has successfully completed the commercialization process of its unique microalgae strain Parachlorella. The bred strain is yellow, so it can only be grown heterotrophically. What is important, lutein is its only pigment and in quantities that make this alga competitive with plants from which lutein is now commercially extracted.The commercialisation partner is the Dutch company Phycom, which is one of the largest European producers of microalgae under strictly controlled heterotrophic cultivation conditions. The company grows 500 tonnes of microalgae per year, but Phycom plans to increase its production significantly. IMIC and Phycom are also partners in the European MULTI-STR3AM project. Thanks are also given to the Centrum transferu technologií AV ČR (Technology Transfer Centre of the Czech Academy of Sciences) for their assistance in the technology transfer.
Sigma Project Award
We are delighted to announce that our successful PhD student and future new postdoc of the algal bio-refinery group, Miss Daniela Bárcenas Pérez, has been awarded a Sigma project by the Technology Agency of the Czech Republic. The objective of the project "Advanced manufacturing based on countercurrent separation to refine microalgae biomass into marketable bioactive pigments" (PigmenTech) is to develop a new manufacturing process based on countercurrent separation (CCC) for the commercial production of lutein, cantaxanthin and astaxanthin diesters from microalgae. R&D activities start at laboratory scale (TRL3) and will be transferred to a real industrial environment, leading to an efficient commercial manufacturing process for the production of biopigments with direct commercial applications.

New published paper
From Laboratory of Photosynthesis - Photosynthetic conversion of solar energy in cyanobacteria, algae and plants is carried out by two complexes of membrane proteins, chlorophyll and other cofactors. These complexes are referred to as photosystems I and II and their efficient assembly depends on the presence of a number of auxiliary protein factors. In the case of oxygen-evolving photosystem II (PSII), such a factor is a protein called Ycf48, which plays a key role in the initial phase of PSII formation, when the central proteins D1 and D2 together form the first intermediate of PSII. However, the exact mechanism of action of Ycf48 and its localization within the d1/D2 complex remained unknown. In this study, we were able to determine the detailed structure of the isolated complex of D1, D2 and Ycf48 proteins by cryoelectron microscopy. It was found that Ycf48 primarily interacts with the D1 protein at the sites where the cluster of calcium and manganese ions binds and performs the conversion of water to molecular oxygen in functional PSII. Thus, the complex prevents the premature binding of these ions, which could lead to oxidative damage to the D1 protein. Read more

Another piece of the "green puzzle" - the Třeboň scientists revealed an important step in the biosynthesis of the photosynthetic apparatus
The work, which was done in collaboration with scientists from Imperial College London, deals with the detailed structure and function of the Ycf48 protein factor, which is crucial for the biogenesis and function of photosynthetic protein complexes (photosystems) of cyanobacteria. The factor is also present in the other oxygen evolving photosynthetic organisms including plants, in which it is even indispensable for the functional photosynthesis. Ycf48 exhibits a doughnut-like shape and it is needed for an effective incorporation of chlorophyll into the membrane protein complexes responsible for photochemical conversion of light energy and oxygen evolution.
