O-Alkylated derivatives of macrolide antibiotics which exhibit improved antibiotic activity can be prepared from parent macrolides having a plurality of reactive hydroxyl groups via a two-step process involving, first, protective esterification of the hydroxy-amino sugar moiety, followed by alkylation at one or more of the remaining hydroxyl groups.

Hirudin can be obtained using a specific DNA sequence in a genetic engineering process. The gene is advantageously synthesised in the form of several fragments which are enzymatically ligated to give two larger part-sequences which are incorporated into hybrid plasmids and amplified in host organisms. The part-sequences are reisolated and then combined to form the complete gene which is incorporat...

A cloudy liquid to be clarified is inserted, after twice receiving flocculation additive, into the bottom of a belt of sludge (4a) in a clarification chamber (4) via a plurality of injectors (22) distributed over the area of said chamber. Uniform distribution of overall flow between these injectors is ensured by internal head loss. The clarified liquid is removed via an upper overflow (4b). Each i...
