The usage of some of the plants which have antimicrobial activities in the protection of food tins

In this study, the effect of the plants which have antimicrobial activities on the healthy preservation of the tomato pastes by taking in to consideration basically their antimicrobial reactions on common microorganisms, is researched.In our research, to start with, the antimicrobial effects of the extracts of some plants (Mentha piperita, Salvia pomifera, Salvia officinalis L., Salvia tomentosa , Sideritis perfoliata, Sideritis sipylea , Sideritis athoa, Micromeria myrtıfolia , Mentha piperita ,Thymus zygoides, Origanum onites,Origanum vulgare, Laurus nobilis , Rosmarinus officinalis , Ocimum basilicum) are tested on microorganisms (Staphylococcus aureus ATCC 50520, Esherichia coli ATCC 707, Pseudomonas aeruginosa ATCC 4615 cultural collections and on Escherichia coli, coagulate Staphylococ, Staphylococcus aureus, Klebsiella pneumoniae 26 clinical isolates )It is confirmed that Mentha piperita, Salvia pomifera, Salvia officinalis L., Salvia tomentosa , Thymus zygoides, Origanum onites, Allium sativum species have antimicrobial effects. Further on the antimicrobial effects of those plants together with some other plants (Raphanus raphanistrum, Origanum majorana, Allium sativum , Zingiber officinale, Salvia fruticosa, Olea europaea) known by their antimicrobial activities, examined on the microorganisms developed in tomato pastes.At the final stage of this study, it is confirmed that the fresh garlic extract has strong antimicrobial effect on the Penicillium griseofulvum, Fusarium flocco , Fusarium oxysporium, Fusarium moniliforme molds developed in tomato paste but has no effect on bacteria. According to our observations, garlic prevents strongly the development of microorganisms. Fresh olive leaf and radish also prevents the microorganism developments in the cultures they are added in ,but the applied doses of mint has no antibacterial noteworthy effect on the microorganisms whose improvement have been studied though it has an antifungal effect.During the laboratory experiments for determination of antimicrobial activities, bacteria are observed in MHA(Müler Hinton Agar) and funguses in PDA(Pateto Dextrose Agar) by traditional pouring and spreading plague methods.
