Minced red chili sample from five traditional market in Padang city have coliform bacteria MPN values range from 12.0 to 240.0 ml sample, and E. Coli bacteria from 7.5 to 240.0 cells / 100 ml sample. Concluded that minced red chili that sold in some traditional market in Padang city is generally not suitable for consumption because it contains E. coli > 3 colonies / g and coliform bacteria > 100 colonies / g.

Researcher was performed in microbiology laboratory of match and science faculty of Andalas Univercity Padang from March from to April in 2013. The researcher used descriptive metode by growing the fungal isolates on rice flour medium (ATB) that aims to identify fungal amylase enzyme which is characterized by the formation of clears areas surrounding the fungal colony.
