A device (1) and a method are provided for treating a porous filtration medium (37) having a receiving unit (2) with of a receiving part (5) and a base part (6). The porous filtration medium (37) can be lifted by the receiving part (5) from a lower part (33) of a filtration device (32), and the receiving part (5) with the porous filtration medium (37) can be mounted on the base part (6). The receiving part (5) is latchable to the base part (6). The base part (6), towards the filtration medium (37) has an incubation chamber (17) connected to a base part (6) outlet (3) that faces away from the receiving part (5), and the outlet (3) has a projection onto which a receiving vessel (4) containing a solvent (28) for dissolving the porous filtration medium (37) can be detachably pushed on.

The invention relates to the fields of bacterial metabolism and the utilization or consumption of short-chain carboxylic acids to reduced products. Specifically, it relates to syngas fermentations using monocultures of syngas-utilizing homoacetogenic bacteria for the production of alcohols using native alcohol dehydrogenase.

A method of detecting a pathogen in a sample. The pathogen from the sample is captured with at least one recognition element. The sample is introduced to a paper-based microfluidic device having spaced electrodes disposed thereon. An impedance magnitude of the sample is measured across the spaced electrodes to detect a presence of the pathogen in the sample. A related paper-based microfluidic device and system are also disclosed.

An object of the present invention is to provide: an algae water concentration system that efficiently concentrates algae water in a culture pond into algae water containing algae having a desired size, with a simple structure and at low cost; and a method for operating the same. A cultured algae water concentration system 100 comprises: an algae water supply unit 17 that has an algae water supply container 18 that stores algae water sent from the culture pond therein, and a supply container outlet port 19 through which the algae water is taken out from the algae water supply container; and an algae water concentration unit that has a concentration container 1 for receiving and concentrating the algae water from the algae water supply unit, a filter 3 which divides the concentration container into upper and lower spaces and does not pass algae having a predetermined size or larger therethrough, a vibration device 5 that vibrates the filter in an out-of-plane direction, a concentration container algae water inlet port 7 which takes in the algae water to the concentration container and is arranged below the filter of the concentration container, a concentrated algae water outlet port 9 that is arranged below the filter of the concentration container and takes out algae water therethrough that has been concentrated in the concentration container, and a filtered water discharge port 8 that is arranged above the filter of the concentration container and discharges filtered water having passed through the filter.
