The agar composition was also different in algae grown in the two media. The starch content was higher in algae grown in natural seawater than in algae grown in enriched seawater, and in algae in both media it increased with increasing irradiance. Since the starch content in Gracilaria can ...
One hundred sixty-five samples of various foods were collected from 24 different Chinese take-out restaurants for bacteriological examination which included enumeration of by three media, MYP, KG and blood agars. Blood agar was less sele... SCHIEMANN, D. A. - 《Journal of Food Protection®》...
coli grown for 24 h in 20 mL of Luria broth (LB) (tryptone 10 g, yeast extract 5 g, NaCl 10 g, 1 L deionised water) nutrient agar was dropped onto LB nutrient agar media (tryptone 10 g, yeast extract 5 g, NaCl 10 g, 15 g agar, 1 L deionised water), and then spread on ...
(A–F) represents the sample composition and testing conditions: (1) fresh capsules; (2) 1 h in simulated gastric fluids; (3) 1 h in simulated intestinal media; (4) 1 h in simulated gastric fluids and 1 h in simulated gastric media. The stability of the capsule coating in the ...
coli cells were plated onto agar culture dishes with the following composition: YT medium containing 1.5% Bacto agar 50 mM sodium phosphate buffer, pH 7.2 1% glucose 10 μg/ml chloramphenicol in the case of E. coli-K1-cells or 10 μg/ml chloramphenicol and 10 μg/ml ampicillin...
Later, the seeds were dried under laminar airflow and were inoculated into sterile test tubes containing half-strength Murashige and Skoog (MS) media (Phytotechnology laboratories, KS) with 0.6% w/v solidified agar. The test tubes were incubated in a growth chamber maintained at 25 °C with ...
Separation of rat serum proteins by zone electrophoresis in agar and starch-gel media has been compared with that obtained by immunoelectrophoresis. Indivi... OW Neuhaus,R Havez,G Biserte - 《Archives of Biochemistry & Biophysics》 被引量: 10发表: 1964年 Electrophoretic study of proteins of hu...
result was recorded. It may be due to the weak contact between the bioplastic films and reference strain in the agar medium. Therefore, the antimicrobial activity was re-evaluated via suppression percentages of reference strains in liquid broth as mentioned in the “Materials and methods” section...
Freshly prepared Mueller-Hinton agar medium (MHA) was transferred to the plates, and with the help of a swab, lines were sown by the sowing technique. Then, film disks (6 mm) containing PPE at 0.125, 0.25, 1.25 and 2.5% w/v and films without extract (negative control) were placed on...
These films showed high thermal stability and maintained their integrity after immersion in different media. The addition of blueberry waste increased UV protection, which is of great interest when films are used as food packaging in order to protect food from the oxidation caused by light. These...
