Ersho is a clear, yellow liquid that accumulates on the surface of fermenting teff-flour batter and is collected to serve as an inoculum for the next fermentation. The pH of ersho samples was about 3.5 and titratable acidity ranged between 3.1% and 5.7%. The mean aerobic mesophilic counts from four households varied between 6.9×106 and 1.3×108 c.f.u./ml and the aerobic bacterial flora consisted of Bacillus spp. Mean yeast counts ranged between 5.2×105 and 1.8×106 c.f.u./ml and comprised, in… 

Isolation and Molecular Identification of Lactic Acid Bacteria Using 16s rRNA Genes from Fermented Teff (Eragrostis tef (Zucc.)) Dough

The presence of different bacterial species in the fermenting teff dough is confirmed and also supports the involvement of various groups of bacterialspecies in the course of the fermentation.

Optimization of teff fermentation by Lactobacillus coryniformis starter culture and investigation of sorghum and buckwheat as substitute components in injera batter

This two-phase study aims first to optimize the fermentation of teff by using Lactobacillus coryniformis as a starter culture and assessed how flour composition influences fermentation kinetic parameters to make recommendations for scaling up the teff fermentation process.

Microbiology of siljo, a traditional Ethiopian fermented legume product

Crude protein, crude fat and ash increased slightly during the fermentation, with final values of around 28%, 25% and 7%, respectively, but there was a marked increase in protein availability and concentration during the fermenting mass.

Molecular Characterization of Fermenting Yeast Species from Fermented Teff Dough during Preparation of Injera Using ITS DNA Sequence

Diversity and distribution of yeasts in indigenous fermented foods and beverages of Ethiopia.

Significant variations were encountered both in yeast cell counts, diversity, and distribution of yeast species among different types of fermentation products and even among different samples of the same types of fermented products.

Review Article: A Review on the Microbiology of Indigenous Fermented Foods and Beverages of Ethiopia

Fermentation is one of the oldest and most economical methods of producing and preserving food and is found to destroy undesirable components, to enhance the nutritive value, flavour and taste of the food, and to make the product safe from pathogenic microorgansisms.
