Introduction. Responses to weak acids, alkalinisation, biocides, UV irradiation, and toxic metal ions.
December 22, 2003... Polluting bacteria can be faced by a wide range of stressing agents and conditions in the aquatic environment, and the ability to resist these and survive depends on several factors (1). First, survival can be significantly affected by the...

Weak organic acids: a panoply of effects on bacteria.
December 22, 2003... Weak organic acids have been used for centuries to preserve foods, but only recently has the possible mechanism for bacterial growth inhibition been investigated. Although the lowering of internal pH was favored as the cause of growth...

Bacterial responses to alkaline stress.
December 22, 2003... Studies of bacterial adaptation to alkaline pH have been less extensive to date compared with those of acidic pH. Recent development of novel methods for global analysis of gene expression under various conditions revealed that many genes were...

Bacterial outer membrane and cell wall penetration and cell destruction by polluting chemical agents and physical conditions.
December 22, 2003... In the environment, bacteria and other microorganisms are subjected to a variety of constantly changing chemical and physical agencies. Chemical ones include antimicrobial compounds (both biocides and antibiotics), pollutants, drugs, cosmetic...

UV radiation-induced enterobacterial responses, other processes that influence UV tolerance and likely environmental significance.
December 22, 2003... The ability of enterobacteria to become UV-tolerant is important because such tolerance may enable organisms to resist irradiation in the environment, in water treatment, in shell-fish, in stages of food processing, and at locations in the...
