A method for producing parenchymal cell cellulose by using a high consistency alkali treatment and an optional refinement step, as well as an apparatus for its manufacture.

Method for producing parenchymal cell cellulose

Disclosed is a composition for embedded three-dimensional microbial culture, the composition including nanofibrillar cellulose and at least one nutrient source. Also disclosed is a method for the manufacture of a composition for embedded three-dimensional microbial culture, the method including the steps of providing nanofibrillar cellulose, mixing the nanofibrillar cellulose with water and at least one nutrient source and optional additives to obtain a mixture, and optionally drying the mixture.

Composition for embedded microbial culture

A composition for fermentation or microbial culture of gram-positive bacteria, includes fibril cellulose and at least one nutrient source including at least one carbon source, at least one nitrogen source, at least one phosphorus source, at least one mineral source and at least one trace element source.

Matrix and composition for microbial culture of gram-positive bacteria

Separation methods based on electrophoresis or chromatography that use a stationary phase including fibril cellulose.

Use of stationary phase comprising fibril cellulose in separation methods

The invention relates to a method for quantitative monitoring of bacterial endospores in an aqueous environment of a paper or board mill. The method comprises at least the following steps: obtaining at least a first aqueous sample originating from the industrial aqueous environment; destroying bacteria in vegetative form in the first sample by a suitable treatment, preferably by heating the first sample to a desired temperature; adding intercalating agent (such as PMA) to the treated first sample and allowing it to interact (e.g. by cross-linking) with the destroyed bacteria, so that the nucleic acid from the destroyed bacteria are unavailable for PCR; and determining the endospore level in the first sample by using quantitative polymerase chain reaction (qPCR) in which only the DNA from the endospores is available for amplification.

Disclosed is the use of a separation agent including fibril cellulose for phase separation, as well as to a method for the separation of at least one liquid phase from at least one phase selected from a second liquid phase, solid phase and semi-solid phase, where the method includes the steps of incorporating a separation agent including fibril cellulose to a mixture where separation of the phases is desired, followed by formation of phases and removing the phases.
