Introduction

The use of natural products, particularly plant extracts, as antimicrobial agents has gained substantial interest in recent years due to the growing concerns associated with antibiotic resistance and the harmful side effects of synthetic antimicrobial compounds (Rios & Recio, 2005). Various fruits are rich in bioactive compounds such as phenolics, flavonoids, and essential oils, which are known for their antioxidant and antimicrobial properties (Bacchetta et al., 2019). This study aims to investigate the antimicrobial effects of different fruit extracts on bacterial growth, providing insights into the potential application of these natural products as alternative antimicrobial agents.

Antimicrobial resistance (AMR) is a significant global health challenge. The World Health Organization (WHO) has classified AMR as one of the top ten global public health threats facing humanity (WHO, 2021). Consequently, there is an urgent need for innovative strategies to combat bacterial infections, particularly those caused by multidrug-resistant strains. Natural fruit extracts present a promising avenue for developing new antimicrobial agents, with many studies identifying antibacterial activity against a range of pathogenic bacteria (Karou et al., 2012).

Fruits such as pomegranate, berries, and citrus fruits have demonstrated notable antibacterial effects. For instance, extracts from pomegranate have shown significant inhibition of the growth of various bacteria including Escherichia coli and Staphylococcus aureus (Hosseini et al., 2015). Similarly, berry extracts, rich in anthocyanins, have been reported to possess antibacterial properties against common foodborne pathogens (McDougall et al., 2011). Citrus fruits, known for their high vitamin C content, also exhibit antimicrobial activity, suggesting that the active compounds within these fruits can be harnessed for therapeutic use (Chang et al., 2009).

This research will focus on the analysis of various fruit extracts and their effects on bacterial growth, using standard microbiological methods such as the disk diffusion assay and minimum inhibitory concentration (MIC) determination. By highlighting the antimicrobial properties of fruit extracts, this study aims to contribute to the identification of potential natural alternatives for combating bacterial infections, thereby addressing the pressing issue of AMR.

Background

The rise of antibiotic-resistant bacteria has prompted researchers to explore alternative sources for antimicrobial agents, and the utilization of plant-derived compounds has emerged as a viable option. Plant materials, particularly fruits, contain a wide array of phytochemicals that can exhibit antibacterial properties. These compounds can disrupt bacterial cell membranes, inhibit enzyme activity, and interfere with nucleic acid synthesis, leading to cell death or growth inhibition (Friedman et al., 2005).

Research has demonstrated that fruit extracts can contain various concentrations of bioactive compounds that vary based on the fruit species, extraction methods, and environmental conditions (Sasikumar et al., 2018). For example, the extraction techniques—such as cold pressing, solvent extraction, or supercritical fluid extraction—can significantly affect the yield and potency of the bioactive compounds (Zhou et al., 2017). Furthermore, the diversity of bacteria in clinical and environmental settings necessitates a comprehensive study of the antimicrobial efficacy of different fruit extracts to determine their potential as therapeutic agents.

In conclusion, understanding the antimicrobial potential of fruit extracts is crucial not only in addressing AMR but also in promoting the usage of sustainable and natural alternatives in the pharmaceutical and food industries. This study aims to provide valuable insights into the effectiveness of various fruit extracts against bacterial pathogens, thus contributing to the ongoing efforts in the discovery of new antimicrobial agents from natural sources.
