Treatment of a zeolite having a SiO2:Al2O3 ratio of at least about 3 with a source of fluoride ions and a source of silicon under hydrolytic conditions including a pH less than 7 results in increase in the SiO2:Al2O3 ratio of the zeolite.

Determining the presence of particular nucleic acid sequence in a test sample comprises (a) chemically modifying nucleic acids in the test sample to introduce a label or a reactive site that supports their hybridisability. (b) contacting under hybridisation conditions the chemically modified sample nucleic acids (MNA's) with a hybridisable nucleic acid probe (NAP) which either, when the sample nuc...

A method for detecting one or more microorganisms or polynucleotide sequences from eukaryotic sources in a nucleic acid-contg. test sample comprises (a) preparing a test sample comprising labelling the nucleic acids in the test sample, (b) preparing one or more probes by immobilising an oligonucleotide or a single-stranded nucleic acid of one of more known microorganisms or sequences from eucaryot...

The cultivation unit comprises of conical containers. The containers (2) alter their cross-section from hexagonal to circular in their lower parts. Such parts are open downwards and, and immediately above the aperture have a part with much greater conicity than the remainder of their structure. - Each container has a number of longitudinal inner ribs (7). Between adjacent containers in a row are h...
