    Abstract

    Today, due to the resistance of microorganisms to antibiotics, the use of medicinal plants to obtain new compounds to overcome them is important and necessary. The aim of this study was to investigate the antimicrobial effects of methanolic and blue lime extracts against bacteria and mold.  In this research, lemon peel extract was extracted by two methods, aqueous and methanol. Then concentrations of 6.25, 12.5, 25 and 50% were prepared from the extracted extracts. Finally, the inhibitory effect of both types of extracts on Staphylococcus aureus, Salmonella typhi, Escherichia coli, Bacillus cereus, Streptococcus pyogenes and Aspergillus flavus was investigated. The method used to measure the diameter of the inhibition halo was by disk diffusion method. The results showed that the methanolic extract extracted from lime peel had the highest and lowest inhibitory effect on Staphylococcus aureus and Bacillus cereus bacteria, respectively. In all types of bacteria tested, except for Escherichia coli, the inhibitory effect of the extracted methanolic extract was greater than that of the aqueous extract. In the case of all tested strains, with the increase in the concentration of the extract, the diameter of the inhibition halo also increased significantly.

    Key words:

    Introduction of Blue Sour Lemon Extract

    Background

    Today, food safety is an important public health issue of society. It is estimated that about 30% of people in industrialized countries suffer from foodborne diseases (Barrett, 2004). According to the report of the World Health Organization, 9 million people in the world die every year due to poisoning caused by consuming contaminated food and water (Oslah et al., 2007). Diseases resulting from the consumption of food contaminated with pathogenic bacteria are very important in public health and cause financial and human losses to societies every year. For example, in Canada, the cost of treating diseases caused by consuming meat contaminated with food pathogens is more than 500 million dollars per year (Osala et al., 2005). In 1999, the Centers for Disease Control and Prevention announced that 76 million people in the United States get sick every year from foodborne pathogens. Such diseases lead to 225,000 hospitalizations and 5,000 deaths annually. According to the assessment of the United States Department of Agriculture, the medical expenses and economic losses caused by the disposal of food causing food diseases are in the range of 6.5 to 34.9 billion dollars per year (Vahidi et al., 2002).

    According to these reports and the need to ensure the food security of the society, the production of healthy, safe and quality food is one of the important goals of food producers (Shahnia and Khaksar, 2013). Therefore, new methods are still needed to reduce or eliminate food pathogens as much as possible in combination with existing methods (Barrett, 2004).

    Since consumers are not sure about the safety of food that contains synthetic preservatives, they tend to consume natural foods that use natural products as preservatives instead of chemical preservatives. One of the ways to produce healthy food is to use materials with natural structure. Using essential oils and plant extracts as antibacterial and antifungal additives is one of these methods. About 3000 types of essential oils are known, and about 300 types are commercially important, especially for the purpose of perfume and seasoning trade, so that some of these essential oils have antimicrobial properties. In addition to the antimicrobial properties of essential oils or their compounds, antiviral, antifungal, anti-toxic, anti-parasitic and anti-insect effects have also been identified (Barrett, 2004).

    In fact, medicinal plants are rich reservoirs of secondary metabolites and in fact are the main effective sources of many medicinal substances. that one or some of their organs contain an effective substance. This substance, which makes up less than 1% of the dry weight of the plant, has medicinal properties effective on living organisms.

    It is not known exactly when plants have been used as medicine by humans. Undoubtedly, information about the effects and properties of medicinal plants has been obtained since ancient times and has finally been handed down to contemporary generations. These efforts have continued to this day and are currently progressing with increasing speed (Tajkarim et al., 2010). Toxicity has increased the use of natural and herbal preservatives and antimicrobials such as essential oils and plant extracts. The use of antibacterial compounds in order to reduce the number of microorganisms in food is very important in terms of food industry and quality control, as well as in terms of public health and safety (Kanalik and Murray, 2001). Because spoiled food, in addition to harming the health of the consumer, also harms the producer economically (Tajkarim et al., 2010).

    One of the ways to control the growth of food pathogenic bacteria is the use of preservatives and antimicrobial compounds. Adding chemicals to preserve food is usually based on preventing microbial growth or killing and destroying groups of harmful microorganisms. Due to public concerns about the side effects of chemical preservatives, there is a tendency to consume products that do not contain preservatives or natural preservatives are used in their use. Plant extracts and essential oils and their constituents have known antibacterial effects (Kanalik and Murray, 2001). New techniques such as high pressure, nanotechnology, radiation, etc. are widely used in neutralizing food properties, while new compounds with functional properties help to improve health. Removal of widely used food additives is demanded, while natural additives are approved for both quality and safety. For this reason, researchers are looking for new sources of compounds or additives. These extracts have antimicrobial properties in several foods (Fernandez-L?pez et al., 2005).

    1-2-1- The advantage of using plant extracts and essential oils

    With the increase in the number of bacterial strains resistant to various antibiotics, many efforts have been made to use the potential power of antimicrobial properties of plants. On the other hand, the emergence of resistant strains among gram-negative bacilli and gram-positive cocci, such as Pseudomonas, Klebsiella, Enterobacter, Staphylococcus, and Enterococcus, has caused problems in the treatment of infections caused by these bacteria (Osalah et al., 2007). This problem is clinically important in the treatment of infections caused by resistant microbial strains (Alof, 1999).
