Consider the unlimited, continuously reinforce medium whose structure is formed by straightened and equally oriented cylindrical fibers having equal circular cross sections.
Unless otherwise noted, the fermentation was carried out in serum bottles, each containing 40 mL of the medium and inoculated with 1% (v/v) of an overnight culture in reinforced clostridial medium (Difco) at 37°C and 250 rpm.
Clostridium strain BOH3 is able to utilize 10 g/l of xylan in reinforced clostridial medium (RCM) and produce butanol and hydrogen.
The aim of this study was to determine the antimicrobial effect of ethanol extract of propolis (EEP) and intracanal medicaments calcium hydroxide, camphorated paramonochlorophenol, and formocresol by means of the macrodilution method using the reinforced clostridial medium (RCM) and brucella and brain heart infusion media.
C. acetobutylicum were grown anaerobically at 37°C in reinforced clostridial medium (RCM) for routine growth and making competent cells [1], [53].
C. strains were grown in reinforced clostridial medium (RCM) [ 24] anaerobically at 37°C.
The strain was stored in 30% (v/v) glycerol at −80°C and was grown in solid reinforced clostridia medium (RCM) at 37°C in an anaerobic chamber (Bug Box, Ruskinn Technology, Leeds, UK).
Before use, all strains were checked for purity by growth on peptone-yeast-glucose-starch (PYGS) and reinforced clostridial medium with 5% (w/v) skim milk agar plates incubated under aerobic and anaerobic atmospheres (Carter et al. 2009).
After chilling on ice, 1 mL was inoculated into 20 mL of reinforced clostridia medium (RCM) (Difco, Detroit, MI, USA) and incubated anaerobically within a serum bottle at 37°C for 12 h.
After C. tyrobutyricum 25755 was pre-cultured using reinforced clostridial medium at 37°C and pH 6.0 under anaerobic conditions, the grown cells were inoculated (10%, v/v) into CGM containing glucose or pre-treated brown algae substituted for glucose.
Bacteria were operated in a DG250 anaerobic workstation (Don Whitley Scientific Limited, West Yorkshire, UK) and cultured on agar plates made by reinforced clostridial medium (RCM, CM0149, Oxoid; Thermo Fisher Biochemicals (Beijing) Ltd., Beijing, China) in anaerobic jars (10 Plate Polycarbonate Jar, A05077; Don Whitley Scientific Limited, UK) at 55°C for 3 days.
