Results obtained from this study tumeric samples containing bacteria with a total range of 23 x 105  cells / ml - 155 x 105  cells / ml. Highest total bacteria recovered in tumeric sold at Gaung market in sample 1 while the lowest total bacteria recovered in tumeric Siteba sold in markets in the sample 1. Tumeric samples from five traditional market in Padang city has coliform bacteria MPN value range from 2.0 to 240.0 ml sel/100 and bacteria E. coli from 4.0 to 240.0 ml sel/100. This proves that tumeric being sold from a number of traditional markets in the city of Padanggenerally not eligible consumed because they contain bacteria E. coli > 3 colonies / g and coliform bacteria >100 colonies / g.

Abstract

 Abstract Tomato (Lycopersicum esculentum Mill) is one of the horticultural plants was found around Peru, Ecuador, Bolivia and quickly spread in to all of world. Tomatoes consist of several nutrients such as vitamins A and C. Tomatoes havealso high content of water and soft texture, therefore tomatoes can not be saved for a long time, they are easy to be damage after harvesting caused by handling and transporting. They are also easy to be contaminated by microorganism such as fungus and bacteria. It will make the tomato decomposed and decayed. The purpose of this research is to inventarisation of fungus found on tomatoes were sold in some markets in Padang.  This  research  has  done  in  laboratory  of Microbiology of the Department  o f Biology,  faculty of Mathematics and Natural Sciences Faculty, Andalas University since February until March 2014. The research used descriptive survey method, and the samples were collected by purposive sampling. The fungi isolated in medium PDA and  characterised  macros- and  microscopicaly for the identification. The result  found three species of fungus, they are Aspergillus niger, Aspergillus parasiticus, Penicillium italicum and Mucor sp
