Antibacterial activity of several Malaysian leaves extracts on the spoilage bacteria of yellow alkaline noodles
Yellow alkaline noodle (YAN) is very susceptible to spoilage and has a short shelf life due to the high moisture content. This study was conducted to isolate and identify spoilage bacteria of YAN in an attempt to apply local plant extracts that possess antibacterial activity in extending the shelf l...
