I am wondering the necessity for this evaluation in different probiotic trials. I appreciate any colleagues who could help me with this question.
Hello, by definition - Antioxidants are compounds that inhibit oxidation. Oxidation is a chemical reaction that can produce free radicals, thereby leading to chain reactions that may damage the bacterial cells also.
Antioxidant activity of probiotics very useful for surviving bacteria in stressful conditions, also antioxidant activity will decrease harmful free radicals in host organism too. So this activity has both effect
1. Increase bacterial survival which is very important parameter for probiotics.
2. Benefit for host organism -decreasing free radicals.
Hope this info will help you.
Good luck!

Thank you so much dear Karen for the perfect explanation. Yes I absolutely got the concept.
So you recommend performing an antioxidant capasity analysis in trials of probiotics, right? @Karen A.Darbinyan
Dear Sepideh,
yes, antioxidant activity is one of important activities of probiotics. If you new in this field I can share with you good review about probiotics.
Thanks Karen, I am familiar with the nutrirional and health-related mechanisms of probiotics.
But quite new in their characteristics and microbiological aspects.
I would appreciate any paper or review in this field.@ Karen A. Darbinyan
Here the nice review about prebiotics and probiotics. If you want papers about biochemistry let me know.
Thank you so much for sharing the file and helping me out with my question Karen A. Darbinyan
The initial screening and selection of probiotics includes testing of the following important criteria: 1.phenotype and genotype stability, including plasmid stability; 2.carbohydrate and protein utilization patterns;
3.survival and growth intestinal epithelial adhesion properties;
4. production of protease resistant bicteriocines;
5. acid tolerance
6. bile tolerance
7. antioxidant activity
also
voluble for industry Inuinase activity, betta calactosidase activity.
And very voluble if you can find sporolactobacillus - sporoforming lactobacilly with any above mentioned activities.
Karen A. Darbinyan Wow! very useful and great information. I have read about some parts of these tests in different papers but none was as complete as your answer. Thanks again for every single worthy answers you made to my question
Your welcome!
If you have any question regarding presented info please let me know.
Good luck!
Metabolites of certain lactobacilli inhibit the formation of reactive oxygen intermediates by suppression of enzymes involved in their formation.
سلام خانم محبوبی
رساله دکترا من دقیقا مرتبط با همین موضوع بوده و نتایج بسیار جالبی به دست آمد این محرک ها باعث تقویت سیستم آر او اس می شوند
برای سنجش آنزیم های آنتی اکسیدانی در چنین مطالعاتی (محرک های ایمنی) روش های زیادی وجود داره که بهترینش سنجش مستقیم از کبد هست
در حال حاضر من ایتالیا هستم و خوشحال میشم بتونم در این زمینه کمکی کنم
موفق باشید
سپاس از پاسخ شما آقای دکتر عاشوری. بسیار عالی. ممنون می شم اگه یک نسخه از مقاله ی پایان نامه ی شما رو داشته باشم. و قطعا از راهنمایی شما بهره مند خواهم شد. با تشکر@ghasem Ashouri
