Five types of pyocins were found in Pseudomonas aeruginosa strain 112. Production of these types was induced by UV irradiation. The pyocin activity was found to be resistant to trypsin treatment. Their molar mass was found to be 282, 251, 112, 89.1 and 54.9 kg/mol, respectively. The pyocins obtained were different from any known type (such as R, S, F) in their chemical and physical properties.
Three types of pyocins were found in Pseudomonas aeruginosa strain 986 and named pyocin type P25, P50, and P70. Production of these types was inducible by UV irradiation. Their molar mass was estimated. The pyocins obtained were different from the known pyocins R, S, and F in their chemical and physical properties. No immunological cross reaction was observed among these pyocins.
Molasses and debis (slurry of dates) can be used as a medium for the growth of yeast. Optimum conditions for the growth of baker's yeast, grown in a medium of molasses and debis have been examined. A temperature of 25 OC. a pH of 4.5, a concentration of 5% (W/V) solution of niolasses or debis and culture shaking are the optimum conditions for the growth of yeast.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
