Production of Nigerian Yoghurt Using Lactic Acid Bacteria as Starter Cultures

Antibiotics and Lactic Acid Starter Cultures " 2

The problem of antibiotics in milk was brought to light in 1948 by Kastli (1948), who was the first to report specifically that milk from a quarter of an udder treated with penicillin would impair the manufacture of butter and cheese. He found that from 0.1 to 1.0 unit of penicillin per ml of milk was sufficient to inhibit the growth of the widely used starter cultures, Streptococcus cremoris a...

Lactic Acid Bacteria as Starter-Cultures for Cheese Processing: Past, Present and Future Developments

Validation of ground-and-formed beef jerky processes using commercial lactic acid bacteria starter cultures as pathogen surrogates.

Beef jerky has been linked to multiple outbreaks of salmonellosis and Escherichia coli O157:H7 infection over the past 40 years. With increasing government scrutiny of jerky-making process lethality, a simple method by which processors can easily validate the lethality of their ground-and-formed beef jerky process against Salmonella' and E. coli O157:H7 is greatly needed. Previous research with...

Preparation of lactic acid bacteria fermented wheat-yoghurt mixtures.

BACKGROUND Tarhana, a wheat-yoghurt fermented mixture, is considered as a good source of saccharides, proteins, some vitamins and minerals. Moreover, their preparation is inexpensive and lactic acid fermentation offers benefits like product preservation, enhancement of nutritive value and sensory properties improvement. The aim of this work was to evaluate changes of some chemical parameters du...

Suitability of MRS-bile Agar for the Selective Enumeration of Mixed Probiotic Bacteria in Presence of Mesophilic Lactic Acid Cultures and Yoghurt Bacteria

Measuring the viability of probiotic microorganisms in food products using plate count methodology is a common practice due to the simplicity (ease of performance), inexpensive and routine testing characters ofthis method. In present study, the suitability of de man rogosa and sharpe agar (MRS) bile agar medium forthe selective enumeration of mixed probiotic bacteria (Lactobacillus ...
