PESTAB (17 references) (French) jThe metabolism of benzamide and its mono- and dichlorinated derivatives by cultures of Aspergillus flavus, A. niger, A. fumigatus, and A. nidulans was studied. Non-substituted benzamide proved to be a good source of nitrogen for all Aspergillus species although it was a source of nitrogen and carbon for A. flavus only. A. flavus utilized 3-chlorobenzamide, 4-chlorobenzamide, and 3,5-dichlorobenzamide as a source of nitrogen; 3-chlorobenzamide and 4-chlorobenzamide served as nitrogen sources for A. fumigatus. A. niger utilized 2-chlorobenzamide, 3-chlorobenzamide, and 2,5-dichlorobenzamide as a nitrogen source. A. flavus metabolized benzamide into protocatechuic acid, 4-chlorobenzamide into 4-chlorobenzoic acid, and 3,5-dichlorobenzamide into 3,5-dichlorobenzoic acid. A. niger metabolized 2-chlorobenzamide into 2-chlorobenzoic acid, and 2,5-dichlorobenzamide into 2,5-dichlorobenzoic acid. The 3-chlorobenzamide was metabolized into 4-hydroxy-3-chlorobenzoic acid by both A. flavus and A. niger, in the presence of other sources of carbon and nitrogen. s,
