Abstract: A method of producing a nutritional supplement from microbial cells. The method includes cultivating microbial cells to obtain a biomass; incubating the biomass with a heat treatment at temperature from 55° C. up to 80° C. for an incubation time from 10 minutes up to 60 minutes; concentrating the biomass by separating and removing a liquid phase from a solid phase to obtain a dry matter content from 2% up to 40% of total weight of the nutritional supplement. Disclosed also is a system of producing a nutritional supplement from microbial cells using the aforementioned method. The system includes a bioreactor; a heat-exchanger and a separator for carrying out the respective steps of the aforementioned method. Reference is made to the Identification of the Microorganism, with the identification reference given by the Depositor SoF1, having the Accession number given by the INTERNATIONAL DEPOSITORY AUTHORITY, VTT E-193585, received on Jun.

Abstract: A power converter for a bioelectrochemical system includes first converters each including a direct current terminal for supplying electric current via electrodes of the bioelectrochemical system, and a second converter for supplying energy to the first converters from an external electric power grid. Each first converter includes an electric element for receiving energy from the second converter and a circuitry for converting voltage of the electric element into electrolysis voltage suitable for the bioelectrochemical system. The electric element can be a secondary winding of a transformer or a direct voltage energy storage. Each first converter is galvanically isolated from the other first converters at least when the first mentioned first converter supplies energy to the bioelectrochemical system. Thus, each first converter drives its own electrode pair without disturbing the other first converters.

Abstract: A bioreactor for growing micro-organisms in a reaction mixture including a reaction medium and micro-organisms. The bioreactor includes a first reaction chamber, a second reaction chamber and means for connecting the first reaction chamber to the second reaction chamber. The first reaction chamber has first volume for containing first number of micro-organisms, a first input for providing reaction mixture thereto, and a first output for removing excess gases therefrom. The second reaction chamber, arranged downstream from first reaction chamber, has a second volume for containing a second number of micro-organisms, a second input for providing gases thereto, and a second output for removing reaction mixture therefrom. The means for connecting is the sole input for allowing the reaction mixture to flow from the first reaction chamber to the second reaction chamber and for gases to flow from the second reaction chamber to the first reaction chamber.

Abstract: A bioreactor for growing micro-organisms, has a reaction chamber containing a reaction mixture with a reaction medium and micro-organisms. A draft tube is arranged inside the reaction chamber, which has a gas inlet, an inlet for the reaction mixture at its first end, and an outlet for the reaction mixture at its second end. The bioreactor includes means for generating flow of the reaction mixture within the reaction chamber and a first blade structure arranged inside the reaction chamber, surrounding the draft tube. The first blade structure has blades arranged at, at least one of an angle ?1 with respect to a direction defined by the height of the reaction chamber, or an angle ?2 with respect to a direction defined by the height of the reaction chamber. The bioreactor also includes an inlet for reaction medium and an outlet for withdrawing medium with grown micro-organisms.

Abstract: A sample port includes a body equipped with an internal cavity and two plungers arranged moveably in the internal cavity, whereby the plungers can be pressed against each other in the internal cavity, in order to compress a sample. At least one of the plungers can be moved into a reactor in order to collect a sample. The sample port also includes a sample chamber, which is formed by a space remaining between the internal cavity and the plungers. At least one sample-container connection is connected in connection with the internal cavity in order to collect the sample from sample chamber. In addition, the sample port has a filter which is provided to at least either plunger for separating a liquid component of the sample from a solid component and means for leading the liquid component of the sample out of the sample chamber.
