A microalgae culture broth producing system includes a device for culture broth sterilization using a micro bubble generator, an air compression and pressure equalization device for the injection of carbon dioxide and oxygen in the atmosphere into the culture broth. The system also includes an air chilling device to maintain suitable culture broth temperature when water temperature is too high, an automatic carbon dioxide supply device to promote photosynthesis, and a sealed vertical photobioreactor to block out pollutants and increase dissolved carbon dioxide and oxygen concentration. The system further includes a high-efficiency harvesting device using hollow fiber membranes, and a hot air drying device using the waste heat generated by air compression.

Methods and systems for preparing clonal cell populations are described. In some instances the disclosed methods comprise: a) identifying and selecting a cell based on its position on a surface or in a container, where the selection is not based on whether the cell comprises an exogenous label or an expressed reporter; b) photoablating all non-selected cells on the surface or in the container; and c) growing a clonal population of the selected cell.

A drying suppression device including: a main body housing a well plate; and an openable/closable lid provided on the main body, the main body including: a holder section that holds the well plate; a liquid storage tank that stores liquid; and a support section that supports the holder while keeping the holder section away from an inner bottom surface of the liquid storage tank, wherein, with the lid being closed, an inner space surrounded by the liquid storage tank and the lid communicate with an outside space.

Embodiments disclosed herein relate to novel flasks, methods and systems employing said novel flasks, and sensors for use within said flasks and systems. In some embodiments, flasks and systems described herein are used to culture cells and/or detect changes in pH levels or dissolved oxygen and/or carbon dioxide levels in a cell culture sample resulting from the growth of living cells contained within a reaction vessel such as a flask. The devices may be used to detect changes in pH and dissolved oxygen levels in a liquid contained in the reaction vessel due to growth of living cells.

A system for growing algae includes a photobioreactor comprising a tubular structure having inner and outer surfaces, an annular space defined between the inner and outer surfaces, an inlet to allow an algae slurry to enter the annular space, and a mechanism configured to produce radially-directed contractions and expansions in the tubular structure. At least one of the inner and outer surfaces is transparent to at least some wavelengths of light useful for growing algae within the algae slurry.

The present invention is related to an anaerobic photobioreactor and a method for active biomass cultivation, wastewater treatment, nutrients recovery, energy production and high-value products synthesis. Phototrophic bacteria are cultured in the anaerobic photobioreactor lighted with solar or artificial irradiation where certain light wavelengths are selectively discarded with a light selector installed on the top of the photobioreactor. In this light-based process wastewater treatment and resources recovery, like nutrients and high-value bioproducts (fertilizers, polymers and proteins) present in wastewater are performed simultaneously. Cultured biomass is treated by anaerobic digestion for biofuel production, including optative hydrolytic pre-treatment, and/or valuable bioproducts can be obtained in a downstream process.

A method detects the presence or absence of at least one first inhibition zone having a culture of biological particles on a culture medium in the presence of a chemical agent. The method of detection has a first step of seeding the culture medium with the biological particles, a second step in which the culture medium receives the chemical agent, a third step of incubation of the culture medium, and a fourth step of measurement of the first inhibition zone of the culture medium, which includes a first phase of taking an image of the first inhibition zone by ombroscopy.
