Abstract :
Citrus fruits are suggested as antimicrobial agents from ancient times.
Several microorganism derived antibiotics currently in use to treat a
variety of human diseases, but the problem of antibiotic resistance is
upcoming rapidly due to various factors. The demand for novel
antimicrobial agents from natural resources has been increased
worldwide. The present study was carried out to find the antimicrobial
activity of pulp juice, whole fruit juice & the combination of citrus fruits
(lemon, orange, sweet lime). Antibacterial analysis showed that lemon
juice was highly active against all the tested organisms, whereas the
orange and sweet lime showed very less & no activity respectively. The
combinations of the three citrus juices were active against all the tested
organisms but the Gram positive bacteria were more sensitive than
Gram negative. The lemon pulp juice also showed a high antifungal
activity against Candida albicans. Furthermore, Nanoparticles with
antimicrobial property, biosynthesized using different sources are of
significance in therapeutic applications of nanotechnology. We also
synthesized Silver Nano particles were from fruit pulp juices. It was
found that the antibacterial activity of lemon was enhanced whereas
orange and sweet lime silver Nano particles were also active against all
test organisms.
