## Abstract The effect of several carbon sources on the production of alkaline phosphatase by the thermotolerant __Aspergillus caespitosus__ was analysed. The fungus released high levels of alkaline phosphatases into the medium after being cultured for long periods with xylan or industrial residues
The toxic effects of 2,4-dichlorophenol on two strains of Escherichia coli harbouring plasmids with p-lactamase activity were studied. The toxicant had a significant effect on growth at concentrations of 12 p g mi-' for the JA 221 (pBR322) strain, as well as at 24 pg rnl-' for the 55-3 (RP4) strain.
