A new plasmid vector is described which can replicate in B. subtilis and which can express and secrete, in the culture medium, human beta interleukin-1 (beta IL-1) without amino acid sequences extraneous to the natural molecule, a strain of B. subtilis transformed by the vector and a method for the expression and secretion of mature human beta interleukin-1. The human beta interleukin-1 thus obtained shows a specific acitvity of 1.times.10.sup.9 U/mg of protein and is particularly suitable as a stimulant for the immune system, as an adjuvant in vaccines for the activation of the repair mechanism in cases of tissue damage, and for the treatment of auto-immune diseases in man.

Expression and secretion of mature human beta interleukin-1 in Bacillus

Process for the inertization of liquid waste, mud and solid waste, containing sulphates and heavy metals, which comprises a neutralization step of the compounds to be treated and an anaerobic reduction step of the sulphate ion to allow the formation of sulphide ions necessary for the process. A consortium of sulphate-reducing bacteria and lactobacilli is used, with whey as a carbon and nitrogen source.

Inertization of liquid waste, mud and solid waste containing heavy

The structural gene encoding isoamylase from Pseudomonas SMP 1 is obtained. Also described are vectors comprising the isoamylase gene and host microorganisms transformed by these vectors. The transformed host microorganisms are capable of expressing and/or secreting mature isoamylase having biological activity.

Cloning of the gene coding the isoamylase enzyme and its use in the
