A multi-wavelength laser diode based optical sensor system capable of monitoring the dynamics and physiological changes of a microorganism culture in real-time. The microorganism culture from a microorganism production chamber is pumped to a flow chamber. Laser diodes emit light at certain wavelengths through the flow chamber, which is sensed by photodiodes. A laser control circuitry is operatively connected to the laser diodes and a signal conditioning circuitry is operatively connected to the photodiodes. A microprocessor reads and records voltage signals corresponding to the wavelengths. A data acquisition system converts said voltage signals into measurements of biological parameters, which are displayed on a graphical user interface and allow a user to monitor the measurements in real time.

One or more light sources may apply stimuli to a colony of organisms. The stimuli may include visible and non-visible light. The stimuli, taken together, may tend to favor survival of organisms that are adapted to perform photosynthesis which involves absorbing energy from infrared or ultraviolet light. In some cases, the set of stimuli may include illuminating the entire colony of organisms with green light, illuminating only a first portion of the colony with pulsed ultraviolet light, and illuminating only a second portion of the colony with pulsed infrared light.

The method comprises an automated removal of cells and/or cell colonies from a cell culture whilst executing a first detection step for selecting cells and/or cell colonies with reference to corporeal and/or physical parameters and detecting position data and storing the detected position data of the selected cells and/or cell colonies in a position database. In order to be able to select special cells and/or cell colonies having special properties from the detected cells and/or cell colonies, at least one second detection step for detecting at least one further parameter of the cells and/or cell colonies is then executed, comparative data from the data of the first and second detection step are created, cells and/or cell colonies are selected with reference to the comparative data and the position data from the position database are transferred to a harvesting unit.
