This was followed by es terification reaction with aliphatic ca rbo xylic ac ids with vary ing chain lengths i.e.
Biological StudySix bacterial s trains Staphylococcus aureus,Bacillus subtilis, Micrococcus luteus, Salmonella setubal, Escherichia coli and Pseudomonas aeruginosa were us ed to check the antibacterial activity of s ome of s ynthes ized a zo xy d ies ters (1, 2,8, 9, 14, 15 and 16) f a liphatic ca rbo xylic ac ids byus ing agar we ll d iffus ion method at 1 mg/ mL (1000g mL-1) concentration.
The compounds 1, 2, 8, 9, 14, 15 and 16 (azo xy dies ters of a liphatic carbo xylic acids ) were s ubjected to check antifungal activity agains t s ix fungal s trains (Mucor species, Aspergillus niger, Aspergillus flavus, Alternaria solani, Fusarium solani and Aspergillus fumigatus) by us ing agar tubedilution method [18, 19] Res ults are pres ented in Table-3.
