Transmission electron and confocal laser scanning (CLSM) microscopies with monoclonal anti-tetrodotoxin antibodies were used to locate tetrodotoxin (TTX) in tissues and gland cells of the ribbon worm Lineus alborostratus. CLSM studies have shown that the toxin is primarily localized in the cutis (special subepidermal layer) of the body wall and in the(More)
The lifecycle of the Bacillus sp. 1839 cultivated during a long period on solid and liquid Youschimizu-Kimura medium was investigated, and then bacteria and spores were studied by light and transmission electron microscopy. Sporulation in this strain is distinguished by engulfment of forespore by mother cell. In the liquid medium, bacteria have the(More)
The marine Bacillus sp. strain 1839 produces tetrodotoxin-like (TTX-like) compounds during sporulation. In this study, the environmental signals that regulate spore formation and the synthesis of TTX-like substances were examined. The main sporulation trigger for Bacillus sp. 1839 was changes in environmental osmolality. Confocal laser scanning (CLSM) and(More)
