Abstract
In the present study, mushrooms, Pleurotus ostreatus and Pleurotus florida, were cultivated on different agricultural wastes namely coffee straw (CS), pea straw (PS), Sorghum Grain Residue (SGR), and Wheat Grain (WG) for the evaluation of antibacterial activity. Antimicrobial activity evaluation was carried out against human pathogenic microorganisms, namely, Escherichia coli, Bacillus subtilis, Streptococcus faecalis, Pseudomonas aeruginosa, and Salmonella typhi by using the disc diffusion method. Methanolic extracts of P. ostreatus cultivated on a Sorghum grain residue substrate were recorded for the highest antibacterial activity against E. coli (19.8 mm) and P. aeruginosa (16.4 mm), and methanolic extracts of P. florida cultivated on a wheat grain substrate were recorded for the highest antibacterial activity against E. coli (18.6 mm) and S. faecalis (14.8 mm). Therefore, results suggested that P. ostreatus and P. florida cultivated on the coffee straw and Sorghum grain substrate were found with the highest antimicrobial activity in comparison to other substrates. The results supported that the methanolic extracts of P. ostreatus and P. florida might indeed be potential sources of antibacterial agents.
Highlights
It should be pointed out that the majority of the extracts present an antimicrobial activity against the tested bacterial species, which is in agreement with the results previously reported by our research group concerning E. coli, K. pneumonia, and P. aeruginosa [20], even when higher extract concentrations were used [21]
Is result is in accordance with the fact that the methanolic extracts of fruiting bodies from both Pleurotus ostreatus and Pleurotus florida contained antibacterial compounds against certain fungal and bacterial pathogens [29]
E result obtained from the study is expected to show the antibacterial activity of Pleurotus species and which Pleurotus species has a high content of antibacterial activity so that they can be used to treat several bacterial diseases
Summary
Mushrooms are a nutritious food source, being rich in protein, vitamins, and minerals. Ey are known to contain substances that enhance the immune system, fight infectious diseases, and lower blood pressure and cholesterol levels. Mushroom is being used as a valuable food source and traditional medicine around the world since ancient times, especially in China and Japan. Mushrooms are rich sources of bioactive compounds such as ß-glucan, proteoglucan, lectin, phenolic compounds, flavonoids, polysaccharides, triterpenoids, diatery fibre, lentinan, schizophyllan, lovastatin, pleuran, steroids, glycopeptides, terpenes, saponins, xanthones, coumarins, alkaloid, purin, purimidin, kinon, fenil propanoid, kalvasin, volvotoksin, flammutoksin, porisin, AHCC, maitake D-fraction, ribonucleas, and eryngeolysin. Pharmacological and nutritional aspects make mushroom as an important tool for the ailment of severe diseases such as microbial and viral infections, cancer, tumor, inflammation, cardiovascular diseases, and immunomodulating diseases [1]
