Antimicrobial agents play the most important role in the treatment of bacterial infections  and wide spread efforts have been carried out by many scientists in order to screen for novel antibiotic producing microbes [2. Methods: in the present study, 134 different actinomycetes, isolated from the soil samples collected from different localities of punjab and himachal pradesh, were screened for antimicrobial activity. Bacterial strains of pseudomonas chlororaphis are aerobic gram-positive bacteria and many of the strains possess a wide-spectrum antifungal activity against soil-borne plant.

Key words: soil, microbes, microbial activity, antimicrobial resistance introduction it is vital for science today to focus on the isolation and characterisation of an unknown organism expressing interesting properties in relation to antimicrobial activity. Antimicrobial activity refers to the process of killing or inhibiting the disease causing microbesvarious antimicrobial agents are used for this purpose antimicrobial may be anti-bacterial, anti-fungal or antiviral they all have different modes of action by which they act to suppress the infection. Abstract | bacterial infections are prevalent in crops and humans, therefore, the need for novel and effective antibacterial compounds to treat, prevent and resist is highly demanded luckily fungi are potential producer of antibacterial natural products the present study was initiated to investigate the antibacterial activity of trichoderma harzianum against phyto and human pathogenic.
The present study was designed to screen and isolate potent bacteria from the rhizosphere soil samples of medicinal plants of kanjamalai hills, salem, tamilnadu, india for antimicrobial activity against human pathogens. Antimicrobial activity of five essential oils against bacteria and fungi responsible for urinary tract infections valentina virginia ebani 1,2, , simona nardoni 1,2. The extracts of t indica and a mannii did not show antibacterial activity against the majority of the bacteria tested, their inhibitory effect being noted against 6/27 (2222%) and 7/27(2592%) bacterial strains tested respectively. Plant extracts of h perforatum exhibited a remarkable activity against bacterial and fungal pathogens, whereas extracts of z capitata did not exhibit any potential antimicrobial activity matrix-assisted laser desorption ionization (maldi) time-of-flight (tof) mass spectrometry (ms) was used to identify plant associated culturable endophytic.
