A method for detecting a lytic activity of one or more types of phages or of the activity of one or more antibiotics with respect to a bacterial strain, the method including using a first multiwell plate, each well receiving a sample containing phages or antibiotics, making at least one deposit on a transparent area of a support, the deposit containing bacteria of the bacterial strain, applying the first plate against the support so that each sample in each well comes into contact with the deposit, for each well, determining, using the detection means, the activity or absence of activity of the phage or antibiotic with respect to the bacterial strain, taking into account the intensity of light signals transmitted through each well and/or the variation thereof over time.

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 system and method for enhancing the wastewater treatment capacity and treatment performance of a biological wastewater treatment or biological culturing process by integrating an illuminated biofilm system with the biological process increasing the inventory of biomass and enhancing the capacity for oxygenation and/or biomass production, as well as improving nutrient removal. Photo-selection or photo-deselection of organisms by actively controlling biofilm erosion, induction of photogranulation and illumination is also presented.

A photobioreactor system includes a frame, a reflective wall coupled to the frame such that the reflective wall defines and circumferentially surrounds an interior chamber, and multiple light sources coupled to the reflective wall such that the multiple light sources circumferentially surround the interior chamber. The interior chamber is configured to receive a container that holds and supports growth of a desired organism.

The present invention relates to a modular system of closed photobioreactors, intended for indoor operation with LED lighting, in an uninterrupted and completely automated manner, with continuous monitoring of process variables, and feedback control of the CO.sub.2 and nutrients, of water temperature along the entire route of the photobioreactor, allowing maximum use of the indoor space where the system is arranged.

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.

A method of determining invasion potential of a tumor cell includes exposing a tumor cell to an activity sensor; after exposing the tumor cell to the activity sensor, stimulating the tumor cell to cause a response in the cell that is reported by the activity sensor; detecting the level of response after stimulation of the tumor cell; and determining the invasion potential of the tumor cell based on the response. A system for determining the invasion potential of a tumor cell includes a sample stage that supports the tumor cell; a stimulator that focuses energy on the tumor cell to stimulate the tumor cell; and an imaging apparatus that observes an effect of the beam on the tumor cell.

Embodiments disclose a device for testing biological specimen. The device includes a sample carrier and a detachable cover. The sample carrier includes a specimen holding area. The detachable cover is placed on top of the specimen holding area. The detachable cover includes a magnifying component configured to align with the specimen holding area. The focal length of the magnifying component is from 0.1 mm to 8.5 mm. The magnifying component has a linear magnification ratio of at least 1. Some embodiments further include a multi-camera configuration. These embodiments include a first camera module and a second camera module arranged to capture one or more images of the first holding area and the second holding area, respectively. The processor may perform different analytic processes on the captured images of different holding areas to determine an outcome with regard to the biological specimen.

The invention relates to a bioreactor comprising a tank containing a culture medium in which a cell culture composed of algae cells is dispersed. The cell culture of algae has a concentration greater than 0.1 g/L in the culture medium, and each algal cell has a minimum absorption in a specific range of wavelengths of light. The bioreactor comprises a light source that is capable of emitting incident light in the direction of the tank, 60% of the photons of the incident light having a wavelength which is included in said specific range of wavelengths of light. The invention also relates to the use of the bioreactor for the production of biomass.
