College, Jaunpur (India) Herbicides Propachlor, basalin, propanil atrazine, monuron and Saturn belonging to different chemical groups were tested for their genetic effect on the N2 – fixing cyanobacterium N. linckia for Kanamycin resistant (KnmR) and their mutagenic potentials were evaluated in comparison to MNNG, a known mutagen to cyanobacteria, over spontaneous frequency. Propachlor, basalin and atrazine like MNNG were found to be more potent mutagen to induce forward mutation (resistant mutant) for Kanamycin (KnmR ) with more frequency than MNNG while propanil, Monuron and saturn were not able to increase the frequency above spontaneous level. https://www.biotech-asia.org/vol4no1/screening-of-herbicides-for-posssible-mutagenicity-in-the-cyanobacterium-nostoc-linckia-and-isolation-of-antibiotic-resistant-strains/ Herbicides; Antibiotics; Mutagen; Genetic effect; MNNG; Nostoc linckia; Kanamycin
