✦ Synopsis

We constructed a plasmid pR4C1 in which a DNA fragment containing the cohesive ends of an actinophage, R4 was inserted into the ClaI site of plasmid pIJ365. The plasmid pR4C1 was packaged efficiently into R4 phage particles in vivo and therefore transferred by transduction. Southern hybridization analysis of DNA from pR4C1transducing R4 phage particles indicated that the plasmid DNA was encapsidated as head-to-tail concatemers with the cohesive ends in the termini. We designated the pR4CI plasmid a cosmid, following the termination of Collins and Hohn (1978).

Plasmid pIF132 containing two direct repeats of the mel (melanin) sequence was used to monitor intraplasmid recombination. Five mutants of Streptomyces lividans TK64 deficient in intraplasmid recombination were isolated. Four contained additional defects in aerial mycelium formation, pigmentation, a

Pulsed-field gel electrophoresis (PFGE) was used to show that insertions of transposon Tn4560 in Streptomyces lividans 66 and the avermectin-producer S. avermitilis are randomly distributed. DNA from the latter strain suffered degradation during electrophoresis that could be avoided by modification

The growth of Streptomyces lividans in defined media was modeled using a simple structured growth model. Conventional unstructured models like Monod kinetics, substrate inhibition kinetics, and the logistic equation were also used in an attempt to fit the data, but the results were all unsatisfactor

## Abstract 17 spontaneous Gal^−^ mutants of __S. coelicolor__ were studied using Southern blottings, but no insertion or deletion mutations were found. 10 mutants of __S. lividans__ included three deletion mutations. The reasons for the lack of insertion mutants are discussed.
