There was a slight difference between the supernatant and cell fractions so that the supernatant specimens produced weak gelatinolytic bands in zymography while hardly anything was seen in the cell fraction series. [ncbi.nlm.nih.gov]

After a weak stirring, the preparation is disposed in cans and incubated for 4h20 at 40 C. until a pH of 4.62. The yoghurt obtained presents a good texture and a very interesting taste for this type of product. [google.com]

Most bacterial proteinases, however, have weak degrading activity against collagen ( Okamoto et al., 2004 ). [academic.oup.com]

The acidification of the cytoplasm induced by the nondissociated form of the weak organic acid leads to the collapse of the proton motive force ( 13 ). [aem.asm.org]

Test strains of S. thermophilus produced 1.5 to 7.7ppm formic acid after the incubation of 16 hours at 37 C (Table 1). [jstage.jst.go.jp]

At an OD 600 of 0.7, [ 35 S]Met was added to the cultures, and samples were withdrawn at different time intervals. Samples equivalent to 0.2 OD 600 units were analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and autoradiography. [aem.asm.org]

The samples were withdrawn at desired intervals and frozen for further analysis. Three cultures of Lactobacillus bulgaricus were used: in MRS broth, in date syrup at concentration 20% and in carob pods syrup medium at concentration 20%. [ejbio.imedpub.com]

Agitation is of 300 turns per minute. The biomass evolution, sugar consumption and lactic acid production are followed at regular time intervals. Analytical methods Sugars were given according to the method of Dubois et al. [ 14 ]. [omicsonline.org]

The agitation speed was set at 300 rpm to insure complete mixing of the fermentation medium. The inocula were incubated at 45 C for 12 h at 300 rpm before their transfer to the fermenter in a 10%. [ejbio.imedpub.com]

It is a gram-positive rod that may appear long and filamentous. It is non-motile and does not form spores. It is regarded as aciduric or acidophilic, since it requires a low pH (around 5.4–4.6) to grow effectively. [en.wikipedia.org]

Introduction Lactobacillus delbrueckii subsp. bulgaricus, a Gram-positive, rod-shaped, non-motile and non-spore-forming lactic acid bacterium (LAB), is one of the most common starter bacterial species in industrial fermentation of dairy products. [nature.com]
