“…If these intermediates of CBAs degradation are not enough quickly degraded they can be subject to the auto-oxidation or enzymatic polymerization with formation of brown or black pigment [73,74]. The presence of this pigment inhibits CBAs degradation by affecting the shape of bacterial cells which may consequently lead to their death as in case of strain Pseudomonas fluorescens [75].…”

“…Chlorobenzoic acids are hazardous and show toxicity to living beings. These compounds show toxicity mainly towards the different systems and metabolism of living beings [5][6] . Chlorobenzoic acid and their derivatives show hepatic changes in rats and other rodents 7 , toxic effects on mammalian brain 8 , cytotoxicity in cultured rat hepatocytes 9 , and genetic degradation 10 .…”

Simultaneous photosensitized dechlorination and decarboxylation of isomeric mono- and dichlorobenzoic acids have been studied in the presence of naphthoxide ion in alkaline medium. The effects of the pH, concentration of the sensitizer, concentration of the substrate, the intensity of the light and the temperature on the rate of the dechlorination have been studied. The quantum efficiency of the photodechlorination has been evaluated. The mechanisms of the photodechlorination and decarboxylation have been suggested. The method is simple, economic and effective.

The biodegradation of four kinds of hydroxamic acids with and without the existence of co-metabolism substrates were studied and compared in the paper. The biodegradation rates of benzohydroxamic acid, salicylic hydroxamic acid, N-hydroxy-phthalimide and H 2 O 5 (2-hydroxy-3-naphthalene A hydroxamic acid) respectively were 68.2%, 78.3%, 56.5%, 7.2% after shaking culture at 25 °C for 96 h in the sole substrate condition. The biodegradation rates of the four kinds of hydroxamic acid were increased to 86.3%, 90.1%, 79.5%, 10.8% with the presence of additional carbon source glucose (120 mg / L), and with the coexistence of carbon source (120 mg / L glucose) and nitrogen source ( 80 mg/ L peptone), the biodegradation rates respectively increased to 99.3 %, 99.8%, 95.2%, 23.7%. The experimental results showed that the presence of co-metabolism substrates significantly improved the biodegradability of benzohydroxamic acid, salicylic hydroxamic acid, N-hydroxy-phthalimide, and slightly improved that of H 2 O 5 .
