Citrus is an important fruit crop in the world and grown almost every state of India and in North East India, Assam lemon is considered as an indigenous principal lemon cultivar of Assam. This research study aimed to analyzed the antibacterial activity of microencapsulated spray dried Citrus limon burm powder by using disk diffusion method against gram-positive Staphylococcus aureus-ATCC 25923 as well as gram- negative Escherichia coli-ATCC 10536 taking gentamicin as positive control and dimethyl sulfoxide (DMSO) as negative control. The inhibition zone was measured using HiAntibiotic Zone Scale-C and results were categorized as resistant, sensitive and in intermediate zone respectively. The end of this exploration study is to assay antibacterial activity of spray dried Citrus limon juice powder as heat can degrade many metabolic compounds and emphasized the antibacterial wealth of spray dried Citrus limon juice powder in exploration of natural sources in storage and transportation for the development of pharmaceutical lead in near future.

Key words : indigenous, antibacterial, microencapsulated, resistant, dimethyl sulfoxide.
