  modified mrs
Growth and lactose metabolism of a Leuconostoc mesenteroides strain were studied in batch cultures at pH 6.5 and 30° C in 101 modified MRS medium sparged with different gases: nitrogen, air and pure oxygen.
      
Two systems were used in the study: MRS- (modified MRS - omitting glucose, acetate and Tween 80) and distilled water (H2O).
      
The effects of pH and temperature were studied during batch fermentation in MRS* medium (modified MRS without ammonium citrate or sodium acetate).
      
While GC medium did not allow any detection of the production of antigonococcal activity by the lactobacilli, both modified MRS and DSA media allowed the detection of this activity by the agar overlay technique.
      
The use of modified MRS medium is recommended since it is less selective than DSA medium for the growth of lactobacilli.

Technology for the separation of bifidobactreial cells is an important intermediate step to obtain the preparation of bifidobacterial products lyophilized. This paper describe a correlation between the harvesting or loss rate of live cells and the survival rate of B.bifidum during centrifugation. Nodified MRS medium as centrifugation vehicle was used to study the effects of centrifuglng force, time and pH in medium on the loss and survival rates of B.bifidum. The optimum conditions for harvesting the highest biomass of the bifidobacteria were also deternined throughout centrifugation. It was shown that once when both centrifugation force and time was increased, the ntalers of living cells lost in supernatant were reduced but at the sane time the survival rate of B. bifidium decreased markedly (P<0. 01). Therefore, the optimim conditions for centrifugation were 3438g (4000r/min) for 10min or 6446g (7500r/min) for 5min. In this case) the highest harvestinq rate of livinq cells was 98 .92% or 98.81%. If given the centrifugation with 3438g for 10min, pH value in media had no siqnificant influence on the harvesting rate of living cells (P>0. 05).

菌体细胞的分离技术是制备双歧杆菌冻干制剂重要的中间工艺环节。本文建立了研究离心过程中活菌收得率与损失率、存活率相关性试验方法。选择改良MRS培养基为离心基质,研究了离心力、离心时间、基质PH对两歧双歧杆菌(B.bifidum)离心损失率和存活率的影响,确定了活菌收得率最高的适宜离心条件。结果表明:增大离心力和延长离心时间,离心损失率和存活率均显著降低(P<0.01);影响离心存活率的阈值为4297g(5000r/min)30min或5157g(6000r/min)20min,最适离心条件3438g(4000r/min)10min或6446g(7500r/min)5min,活菌收得率高达98.92%或98.81%;选取3438g(4000r/min10min离心,基质pH对活菌收得率无显著影响(>0.05)。
