Monitoring of the booster biocide dichlofluanid in water and marine sediment of Greek marinas.
Dichlofluanid (N-dichlorofluoromethylthio-N'-dimethyl-N-phenylsulphamide) is used as booster biocide in antifouling paints. The occurrence of dichlofluanid and its metabolite DMSA
Rhizocticin A, an antifungal phosphono-oligopeptide of Bacillus subtilis ATCC 6633: biological properties
Rhizocticin A, the main component of the antifungal, hydrophilic phosphono-oligopeptides of Bacillus subtilis ATCC 6633, was used for sensitivity testing and experiments into the molecular mechanism
Antifungal effects of bacilysin and fengymycin from Bacillus subtilis F-29-3. A comparison with activities of other Bacillus antibiotics
Bacilysin production, formerly known for a few strains only, could be demonstrated for all 12 wild-type cultures of Bacillus subtilis tested during this study, and fengymycin, a complex of closely related lipopeptide components, shows antibiotic activity against filamentous fungi.
3 R&D in material protection: new biocides
Active ingredients are without any doubt the most important factor of success in the material protection business. Basically, the whole business relies on the availability of biocides which combine
Critical Aspects in the Determination of the Antifouling Compound Dichlofluanid and its Metabolite DMSA (N,N-dimethyl-N'-phenylsulfamide) in Seawater and Marine Sediments
A straightforward method based on GC-MS was developed to determine the booster biocide dichlofluanid and its metabolite DMSA in sediment and water. Special attention was paid to conservation of
Rhizocticins — New phosphono-oligopeptides with antifungal activity
The widely used and well-known bacterial strain Bacillus subtilis ATCC 6633 was found to produce two novel, antifungal hydrophilic peptide antibiotics, L-arginyl-L-2-amino-5-phosphono-3-cis-pentenoic
A new bactericidal lead structure for the protection of materials.
The synthesis and biological evaluation as well as a first toxicological assessment of these compounds are described, which show strong bactericidal activity down to levels of below 100 ppm but unfortunately increases the number of mutations in Ames tests.
Combination Dimethyldicarbonate / potassium sorbate / ascorbic acid for sterilizing non-carbonated and carbonated beverages
A preservative is disclosed containing dimethyl dicarbonate, potassium sorbate and/or sodium benzoate, and ascorbic acid.
