Six oligosporogenic (Spo−) mutant strains of Bacillus thuringiensis were selected from survivors of treatment with N-methyl-N′-nitro-N-nitrosoguanidine. Each strain was blocked at or before stage II of spore development, but all produced typical bipyramidal-shaped crystalline inclusion bodies. Toxicity of the parasporal endotoxin isolated from the mutant strains was assayed by an in vitro technique using cultured insect cells, and was comparable with that of normal wild-type parasporal protein. Multiple parasporal inclusion bodies per cell were often produced, and smaller embedded particles were numerous and distinct.

A dye-decolorizing peroxidase (DyP) from Irpex lacteus was cloned and heterologously expressed as inclusion bodies in Escherichia coli. The protein was purified in one chromatographic step after its in vitro activation. It was active on ABTS, 2,6-dimethoxyphenol (DMP), and anthraquinoid and azo dyes as reported for other fungal DyPs, but it was also able to oxidize Mn2+ (as manganese peroxidases and versatile peroxidases) and veratryl alcohol (VA) (as lignin peroxidases and versatile peroxidases). This corroborated that I. lacteus DyPs are the only enzymes able to oxidize high redox potential dyes, VA and Mn+2. Phylogenetic analysis grouped this enzyme with other type D-DyPs from basidiomycetes. In addition to its interest for dye decolorization, the results of the transformation of softwood and hardwood lignosulfonates suggest a putative biological role of this enzyme in the degradation of phenolic lignin.

We report the isolation and characterization of a new bacteriocin, thuricin S, produced by the Bacillus thuringiensis subsp. entomocidus HD198 strain. This antibacterial activity is sensitive to proteinase K, is heat-stable, and is stable at a variety of pH values (3–10.5). The monoisotopic mass of thuricin S purified by high perfomance liquid chromatography, as determined with mass spectrometry ESI-TOF-MS, is 3137.61 Da. Edman sequencing and NanoESI-MS/MS experiments provided the sequence of the 18 N-terminal amino acids. Interestingly, thuricin S has the same N-terminal sequence (DWTXWSXL) as bacthuricin F4 and thuricin 17, produced by B. thuringiensis strains BUPM4 and NEB17, respectively, and could therefore be classified as a new subclass IId bacteriocin.
