Metal oxides are extracted from coal fly ash by a bio-leading process. The ash is suspended in an aqueous saline solution having a pH within the range of from 5 to 8 and the suspension is incubated with a microorganism strain capable of growing in aqueous saline solution and binding to metal oxide, and the resulting agglomerates are separated. A new gram-positive bacterial strain designated GIN-1 and being a member of the genus Rhodococcus is described. It has been deposited under No. 40340 at the National Collections of Industrial and Marine Bacterial Ltd. (NCIMB) at Aberdeen, Scotland. GIN-1 is particularly suitable for the bioteching of metal oxides from coal fly ash.

Extraction of metal oxides from coal fly ash by microorganisms and a new

A single-step procedure for the immobilization of antibodies, comprising reacting a purified antibody with buffered periodate in an amount sufficient to produce aldehyde groups in the presence of a polymer carrier material which has been modified with adipic acid dihydrazide is disclosed. The present invention provides dramatic improvements in activity. and yield of immobilized antibody over the prior multi-step procedure employing separate oxidation and immobilization steps.

Process for the production of immobilized antibodies

Antibodies which are immobilized and covalently bound to a matrix polymer by means of a modification in a carbohydrate region of the antibodies; wherein the binding of the antibodies is effected by condensing at least one aldehyde group in an oxidized carbohydrate region and at least one epoxide function of an epoxy-group-containing matrix polymer, said condensation being conducted in the presence of a bifunctional reagent which has, on one end position of a spacer unit having at least three members, an amino group capable of condensing with the aldehyde group, and which has on the other end position a group which reacts covalently with the epoxide function.
