Antibacterial activity of Chrysanthemum indicum, Centella asiatica and Andrographis paniculata on Bacillus cereus and Listeria monocytogenes under Low pH Stress (2012)
Classic food preservation methods do not guarantee to inhibit Bacillus cereus and Listeria monocytogenes growth. The application of natural antibacterial agent is an alternative way to control their growth. Asia herbs, Chrysanthemum indicum, Centella asiatica, and Andrographis paniculata were used in this experiment to test their antibacterial activity under low pH stress. Their antibacterial activities of 95% ethanolic crude extracts were tested on B. cereus and L. monocytogenes 10403S under different low pH stress by agar disc diffusion ...
Effect of extraction and shaking time on antibacterial activity of dry centella asiatica againts food pathogenic microorganisms (School of Biotechnology, Assumption University of Thailand, 2014-07)
The outbreaks caused by pathogenic bacteria still being a major human health and food industry problem. Since time immemorial, people used plant material as medicine and nowadays, it widely used as tea preparation. Centella asiatica is a potential herbs related to its antibacterial activity. Therefore, this study aimed to investigate the antibacterial activity of dry C. asiatica crude 95% ethanolic extract under different extraction time (1, 3, 5, and 7 days) and shaking action (120 ...
Effect of solvent and time extraction on antibacterial activity of Acacia concinna's pod against Bacillus cereus (2015-09)
Herb extract becomes the great interesting functional ingredient. Acacia concinna -poi pod) is a potential herb as the functional ingredient. Therefore, this study aimed to investigate the effect of extraction solvent and time on antibacterial activity of dry A. concinna Bacillus cereus. The agar disc diffusion method was used to evaluate the antibacterial activity of A. concinna ts using Muller Hinton Agar media (MHA). The 20 g dry A. concinna solvents; water, 95% ethanol and ...
