This a study aimed to evaluate the effects of different fermentation conditions; including temperature (30; 42 °C); salt concentrations (2; 4 and 6%); pH (4.5; 5 and 6); and their interaction effects on the production of short-chain fatty acids (acetic acid; propionic acid; isobutyric acid; butyric acid; isovaleric acid; valeric acid) by Lactobacillus fermentum ATCC 9338; Lactobacillus fermentum 19SH and Lactobacillus acidophilus ATCC 4356. Once grown under different fermentation conditions; supernatants and pellets of fermentation media were separated; and then SCFAs were measured using Gas chromatography/mass spectrometry (GC-MS). Results revealed that fatty acid content was altered in each fermentation condition; and the highest amount after lactic acid belonged to propionic acid. Accordingly; Lb. Fermentum 19sh; Lb. Fermentum ATCC9938; and Lb. Acidophilus ATCC4356 produced the highest levels of isovaleric acid; acetic acid; propionic acid; isobutyric acid; butyric acid; and valeric acids; respectively. The results indicated a relationship between the production of short-chain fatty acids and the growth of bacterial strains and cell membrane characteristics.},
