Abstract: A transformant selection system has been developed, particularly for a .beta.-lactam producing strain, more particularly for P. chrysogenum, by the complementation of a mutation of said .beta.-lactam producing strain by a homologous selection marker without interfering with .beta.-lactam biosynthesis. Particularly, in applying said transformant selection system a positive selection agent, for instance fluoroacetate is used for the isolation of fac mutants of said strain, particularly of said .beta.-lactam producing strain. Furthermore, a gene entitled facA has been isolated from P. chrysogenum.

Abstract: An enzymatic process for the conversion of glucose into gluconic acid, uses concentrated glucose solutions. The process employs a combination of glucose oxidase and catalase enzymes which may be obtained from an Aspergilltus niger strain and has a high ratio of catalase;glucose oxidase activity. The enzymatic process requires less time than conventional fermentation processes, the yield of the conversion is close to 100% and the obtained gluconic acid/gluconate solutions do not contain impurities.
Abstract: Novel methods and compositions are provided for the enhanced production of .beta.-lactam antibiotics. The process is exemplified by the production of penicillin. In addition, the P. chrysogenum and A. chrysogenum .delta.-(L-.alpha.-aminoadipyl)-L-cysteinyl-D-valine synthetase genes have been isolated and sequenced. Also methods are provided for the production of .delta.-(L-.alpha.-aminoadipyl)-L-cysteinyl-D-valine synthetase using recombined DNA techniques.

Abstract: The present invention discloses a selection marker free system which can be used to introduce genetic modifications in bacteria, yeasts and fungi. The system can be employed to introduce or delete desired genes or DNA fragments in the genome of the indicated host species without leaving any undesired DNA i.e. the selection marker used for selection of transformants or other DNA used for cloning. In this way strains have been developed containing only desired genes introduced at desired chromosomal sites. Similarly, desired DNA fragments have been deleted or replaced at desired sites.

Abstract: A nucleotide sequence encoding phytase has been isolated and cloned. The coding sequence has been inserted into an expression construct which in turn has been inserted into a vector capable of transforming a microbial expression host. The transformed microbial hosts may be used to economically produce phytase on an industrial scale. The phytase produced via the present invention may be used in a variety of processes requiring the conversion of phytate to inositol and inorganic phosphate.
