Abstract
Description
Werkwijze ter verkrijging van cellulose.Method for obtaining cellulose.
De uitvinding heeft betrekking op een nieuwe werkwijze ter verkrijging van cellulose.The invention relates to a new method for obtaining cellulose.
Het doel van de uitvinding is de verkrijging van een andere goede werkwijze voor het produceren van cellulose die gebruik maakt van algen. Het gebruik van algen is vooral aantrekkelijk omdat de algen gekweekt kunnen worden in grote vijvers. Deze vijvers kunnen gebruikt worden voor de verwerking van mest.The object of the invention is to obtain another good method for producing cellulose using algae. The use of algae is especially attractive because the algae can be grown in large ponds. These ponds can be used for manure processing.
Het doel wordt bereikt door gebruikmaking van algen in het bijzonder Crinalium epipsammum. Dit is een cyanobacterie die is geïsoleerd uit een algenkorst uit de binnenduinen van Meyendel bij Den Haag. Deze alg is inmiddels geregistreerd in het soortenregister voor algen te Göttingen onder nummer SAB 22.89..The object is achieved by using algae, in particular Crinalium epipsammum. This is a cyanobacterium isolated from an algae crust from the inner dunes of Meyendel near The Hague. This alga is now registered in the species register for algae in Göttingen under number SAB 22.89.
Crinalium epipsammum vormt korte rechte trichomen welke een afgeplatte vorm hebben. De trichomen versmallen niet naar het einde toe. Vertakkingen zijn niet gevonden. De breedte van de trichomen is 5-7 μ, de dikte 1,5 μ en de celllengte is 1,5-2 μ. De lengte van de trichomen kan variëren afhankelijk van de kultuurcondities. De geïsoleerde stam vertoonde geen celdifferentiatie en hormogoniën worden eveneens niet gevormd. De trichomen zijn niet beweeglijk. De celdeling is volgens het Oscillatoria-type.Crinalium epipsammum forms short straight trichomes that have a flattened shape. The trichomes do not narrow towards the end. Branches were not found. The width of the trichomes is 5-7 μ, the thickness 1.5 μ, and the cell length is 1.5-2 μ. The length of the trichomes can vary depending on the culture conditions. The isolated strain showed no cell differentiation and hormogonias are not formed either. The trichomes are not mobile. The cell division is according to the Oscillatoria type.
Met behulp van transmissie electron mikroscopische opnamen is de ultrastruktuur onderzocht. Hierbij is gebleken dat de celwand opvallend dik is gebleken: ± 100 nm. De dikte en de hoeveelheid N-acetyl-muramine zuur, een component van peptide glycaan, is vergelijkbaar met die van Gram-positieve bacteriën.The ultrastructure was examined with the aid of transmission electron microscopic images. It has been found that the cell wall has turned out to be remarkably thick: ± 100 nm. The thickness and amount of N-acetyl-muramic acid, a component of peptide glycan, is comparable to that of Gram-positive bacteria.
Nieuw is de aanwezigheid van poly-ß-(l-4)glycaan, een type cellulose. Dit is de eerste keer dat bij cyanobacteriën dit polymeer is aangetroffen. Het cellulose komt niet in de kristallijnige vorm voor zoals bij hogere planten, maar kristalliseert uit na milde zuurbehandeling. In de Verenigde Staten is men in een vergevorderd stadium met de ontwikkeling tot verwerking van dit soort cellulose.New is the presence of poly-ß- (1-4) glycan, a type of cellulose. This is the first time that this polymer has been found in cyanobacteria. The cellulose does not exist in the crystalline form as in higher plants, but crystallizes after mild acid treatment. The United States is at an advanced stage of development into the processing of this type of cellulose.
In de figuur is een afbeelding te zien van Crinalium epipsammum gekweekt in continu cultuur waarin A de lengtedoorsnede van de trichoom weergeeft en B de dwarsdoorsnede van de trichoom weergeeft. De schaalstreep representeert 7 μ.The figure shows an image of Crinalium epipsammum grown in continuous culture in which A represents the longitudinal section of the trichome and B represents the cross-section of the trichome. The scale bar represents 7 μ.
