Phsysical Methods of Microbial Control: Moist Heat: Kills microorganisms by coagulating their proteins. In general, moist heat is much more effective than dry heat. u Boiling: Heat to 100 oC or more at sea level.

Once infants ingest Clostridium botulinum spores the spores escape being killed in the stomach due to the fact that they produce lower levels of acid in their stomach. The intestines of the infants also lack the proper number of normal bacterial flora to prevent the growth of the vegetative Clostridium botulinum cells. Define vegetative cell.

Ø The endospore core has a normal cell structure as that of a vegetative cell. Ø The core contains ribosomes and centrally placed nucleoid (genetic material). Ø Unlike the vegetative cells, the core protoplast is metabolically inactive.

all were phase‐bright spores ( Russel 1990 ). After irradiation of the spores, no growth was observed by plate‐count tests, whereas NaBr‐purified spores that were not irradiated grew well on TSA and colony morphologies were as expected. Vegetative microorganisms can generally be killed at temperatures from 50°C to 70°C with moist heat. Bacterial endospores , however, are very resistant to heat and extended exposure to much higher temperature is necessary for their destruction.

High concentrations of sugars or salts decreases the water content of the medium and thus, increases the exposure time. Most vegetative cells are killed almost instantaneously at 100 °C and their D values are measured and expressed at temperatures appropriate to pasteurization. Bacterial spores are usually far more heat resistant than vegetative cells; thermophiles produce the most heat resistant spores while those of psychrotrophs and psychrophiles are most Whereas the vegetative cells could be inactivated much more efficiently at increased temperature and altered index of pH, the production of 1O2 remained essentially the same under these alterations. Additionally, the relations among the sensitivities of different cell types to be killed by our photodynamic treatments (PDT) were opposite to This works by killing vegetative cells, allowing germination of surviving spores, and killing the resulting vegetative cells before they have time to form further spores. Any surviving spores from the first treatment, or incidentally formed spores during the first incubation period, are killed in a third steaming cycle. A stained preparation of the cell Bacillus subtilis showing endospores as green and the vegetative cell as red Phase-bright endospores of Paenibacillus alvei imaged with phase-contrast microscopy An endospore is a dormant , tough, and non-reproductive structure produced by some bacteria in the phylum Firmicutes . Several investigators showed that ≥2% aqueous solutions of glutaraldehyde, buffered to pH 7.5–8.5 with sodium bicarbonate effectively killed vegetative bacteria in <2 minutes; M. tuberculosis, fungi, and viruses in <10 minutes; and spores of Bacillus and Clostridium species in 3 hours 542, 592-597.
