The Philippines is known to be the world's best manufacturer of Musa textilis commonly known as abaca, supplying around 87.5% of the world's leading demands. However, in an abaca stalk the farmer could only recover 0.3 - 0.5 kg of fresh fiber and the rest will go to waste. Hence, looking for ways on how to utilize abaca is empirical. The knowledge generated from this research may give us an insight as to how we can use the abaca plants processing wastes as resources, such as its antimicrobial properties. This study was conducted to determine the antimicrobial properties of the different parts of abaca (corm, flower, leaves, pseudostem, and roots) against E. coli, compare the antimicrobial properties of the extract by testing it against the bacterial wilt of tomato, R. solonacearum, using a preventive and curative method, quantify the total phytochemical content of M. textilis extracts in terms of total phenolic and total flavonoid contents and evaluate the toxicity of the extracts using a yeast cell model. The results showed that the different parts of abaca can inhibit the growth of E. coli at concentrations of 5,000ppm, 10,000ppm, and 15,000ppm. Abaca plant extracts were also found effective as a protective coating against R. solonacearum however, it was observed that higher concentrations were needed in order for the seedling to have a more successful survival rate. The different parts of the abaca were also analyzed for phytochemical contents and all parts of the abaca plant contained high amounts of flavonoid and phenols. Lastly, the toxicity test conducted showed that the abaca extracts were found to be non-toxic.
