The multi-fixed-bed bioreactor “Multiferm” provides a downscaled system for the development of fixed-bed processes with immobilized microorganisms or cells. It consists of twelve single fixed-bed units that can be operated independently. Different bacterial strains, carriers used for immobilization, media or flow rates can be studied in one compact experimental set-up. Experiments can be run in...

Lactobacillus delbrueckii subsp. bulgaricus LBB.B5 originates from homemade Bulgarian yogurt and was selected for its ability to form a strong association with Streptococcus thermophilus The genome sequence will facilitate elucidating the genetic background behind the contribution of LBB.B5 to the taste and aroma of yogurt and its exceptional protocooperation with S. thermophilus.

Immune senescence potentially leads to an increased risk of infections. It is desirable to augment the immune system and protect against infections by daily consumption of immunostimulatory food. The present study evaluated whether the intake of yoghurt fermented with Lactobacillus delbrueckii ssp. bulgaricus (L. bulgaricus) OLL1073R-1 has an effect on resistance to the common cold. We conducte...

Abstract Fermentation of quinoa by probiotics provides higher nutritional value and can be considered as a significant source bioactive compounds alive for the human body. Moringa leaves powder (MLP) at levels 0.25 0.50% were used an additional prebiotic to supply fermentation Lactobacillus plantaram ATCC 14917 delbrueckii ssp. Bulgaricus EMCC 11102 produce healthier products. The results indic...

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 ...

Bu çalışmada, Kefir üretiminde farklı Lactobacillus (Lactobacillus delbrueckii ssp. bulgaricus ATCC 11842, helveticus 15009 ve plantarum 14917) ilave kültür kullanımının ACE inhibisyon aktivitesi patojenik bakterilere karşı antimikrobiyal aktivite gibi biyoaktif özellikleri üzerine etkisi araştırılmış proteoliz (HPLC peptit profilleri, HPLC serbest amino asit profilleri) incelenmiştir. Antimikr...

AIM The aim of the study was to assess the impact of the long-term use of the composite probiotics in patients after restorative proctocolectomy. METHOD Forty-three patients (20 females and 23 males, aged 21 to 68 years) after restorative proctocolectomy were included in the study. After randomization patients were divided into placebo group and treatment group with oral intake of probiotic c...

The Lactobacillus acidophilus homology group comprises Gram-positive species that include L. acidophilus, L. helveticus, L. crispatus, L. amylovorus, L. gallinarum, L. delbrueckii subsp. bulgaricus, L. gasseri, and L. johnsonii. While these bacteria are closely related, they have varied ecological lifestyles as dairy and food fermenters, allochthonous probiotics, or autochthonous commensals of ...

In the present work, the effect of milk supplementation on viability of yogurt bacteria (Streptococcus thermophilus and Lactobacillus delbrueckii subsp. bulgaricus) and probiotic bacteria (Lactobacillus acidophilus and Bifidobacteria) was studied during yogurt manufacture and thirty three days storage. Incubation time to reach pH value of 4.5 was greatly affected by the addition of casein fract...
