Identification of deep-sea-sediment bacteria which produce tetrodotoxin.
Forty-nine bacterial strains were isolated from deep-sea sediments. Among them, 22 strains were shown by the tissue culture assay method to produce sodium channel blockers. For some strains, high-performance liquid chromatography analysis confirmed that the blocker was tetrodotoxin. Tetrodotoxin-producing bacteria seem to be widespread in marine sediment.
متن کاملNo ability to produce tetrodotoxin in bacteria.
Bacterial production of tetrodotoxin (TTX) was first reported by Yasumoto et al. (8). Detection of bacterially produced TTX has been primarily by high-performance liquid chromatography (HPLC) and gas chromatography-mass spectrometry (GC-MS). In September 1995, Applied and Environmental Microbiology published a paper indicating that both the HPLC and GC-MS methods lacked specificity for TTX (3)....
متن کاملPresence of tetrodotoxin and tetrodotoxin-producing bacteria in freshwater sediments.
The occurrence of tetrodotoxin (TTX) in sediment from Lake Suwa, Japan, was confirmed by a tissue culture assay, high-performance liquid chromatography, and gas chromatography-mass spectrometry. Altogether, 17 TTX-producing bacteria belonging to five genera were isolated from Lake Suwa and Pond Inokasira. Our results indicate that TTX and TTX-producing bacteria occur even in freshwater environm...
متن کاملGram-negative bacteria produce membrane vesicles which are capable of killing other bacteria.
Naturally produced membrane vesicles (MVs), isolated from 15 strains of gram-negative bacteria (Citrobacter, Enterobacter, Escherichia, Klebsiella, Morganella, Proteus, Salmonella, and Shigella strains), lysed many gram-positive (including Mycobacterium) and gram-negative cultures. Peptidoglycan zymograms suggested that MVs contained peptidoglycan hydrolases, and electron microscopy revealed th...
متن کاملA marine sponge associated strain of Bacillus subtilis and other marine bacteria can produce anticholinesterase compounds
BACKGROUND Acetylcholinesterase (AChE) inhibitors or anticholinesterases reduce the activity of enzyme acetylcholinesterase that degrades the neurotransmitter acetylcholine in the brain. The inhibitors have a significant pharmacological role in neurodegenerative diseases like Alzheimer's and Parkinson's etc. Although plants have been a significant source of these compounds, there are very few s...
