Inhibition of germination of Bacillus cereus T spores by phenylglyoxal. 1979

B P Ram, and R S Rana, and K G Gollakota

Phenylgloxal at a concentration of 0.6 mM inhibited germination of Bacillus cereus T spores as characterized by a decrease in absorbance, dipicolinic acid and loss in heat resistance in a chemically defined growth and sporulation medium. In a germination medium containing L-alanine and adenosine, phenylglyoxal inhibited decrease in absorbance and affected partial loss of viability. It is postulated that phenylglyoxal interacts with free amino groups of various enzymes or amino compounds present in the spore structure thereby causing the inhibition of germination.

UI	MeSH Term	Description	Entries
D010848	Picolinic Acids	Compounds with general formula C5H4N(CO2H) derived from PYRIDINE, having a carboxylic acid substituent at the 2-position.	Acids, Picolinic
D003470	Culture Media	Any liquid or solid preparation made specifically for the growth, storage, or transport of microorganisms or other types of cells. The variety of media that exist allow for the culturing of specific microorganisms and cell types, such as differential media, selective media, test media, and defined media. Solid media consist of liquid media that have been solidified with an agent such as AGAR or GELATIN.	Media, Culture
D006037	Glyoxal	A 2-carbon aldehyde with carbonyl groups on both carbons.	Ethanedial,Ethanedione
D000241	Adenosine	A nucleoside that is composed of ADENINE and D-RIBOSE. Adenosine or adenosine derivatives play many important biological roles in addition to being components of DNA and RNA. Adenosine itself is a neurotransmitter.	Adenocard,Adenoscan
D000409	Alanine	A non-essential amino acid that occurs in high levels in its free state in plasma. It is produced from pyruvate by transamination. It is involved in sugar and acid metabolism, increases IMMUNITY, and provides energy for muscle tissue, BRAIN, and the CENTRAL NERVOUS SYSTEM.
