Stability evaluation of lyophilized probiotic bacteria

Probiotic Properties of Lyophilized Cell Free Extract of Lactobacillus casei

BACKGROUND In recent years there have been considerable interests in the use of probiotic live cells for nutritional and therapeutic purposes. This strategy can be concomitant with some limitations such as survival of live cell during the GI-transit and their effective delivery to target tissues upon ingestion. Several attempts have been made to overcome these limitations such as their microenc...

Microencapsulation of Probiotic Bacteria:

In the recent past, there has been an explosion of probiotic health-based products. Many reports indicated that there is poor survival of probiotic bacteria in these products. Further, the survival of these bacteria in the human gastro-intestinal system is questionable. Providing probiotic living cells with a physical barrier against adverse environmental conditions is therefore an approach cur...

Survival of bacteria in lyophilized plasma.

Although lyophilization reduces the bacterial population in plasma, some species survive for several months. Sensitivity or resistance to lyophilization in plasma is a characteristic of each morphological type, with gram-negative species being more sensitive to destruction than cocci or sporulating gram-positive species. Reconstituted preparations of lyophilized plasma must be incubated for 24 ...

Pili in Probiotic Bacteria

The ability to adhere to intestinal epithelial tissue and mucosal surfaces is a key criterion in selecting probiotics. Adhesion is considered to be a prerequisite for successful colonization and survival in the gastrointestinal tract to provide persistent beneficial effects to the host. Bacteria express a multitude of surface components that mediate adherence. Pili or fimbriae are surface adhes...
