Characterization of short chain fatty acids in microbial cultures by DART-MS and GC-MS
… disease. Analysis of the results of mono- and co-cultures in in vitro systems has led to the conclusion that diverse microbial organisms may each contribute in part to the complete metabolism to produce SCFA. GC- MS and DART- MS were investigated as analytical tools in the present study to …

Influence of an Irrigation System Utilizing Apical Negative Pressure on Bacterial Elimination during Endodontic Therapy: a prospective randomized clinical study
… 0.5% NaOCl as the primary irrigant. Surface microbial cultures (S1) (obtained prior to access), and 2 intra-canal microbial cultures (S2 and S3) were obtained before and after chemomechanical preparation for each irrigation method. The samples were cultivated in anaerobic conditions for 1 …

pH control in a miniaturized bioreactor
… efficiency of the screening process for various microbial cultures. Unlike larger reactors currently in use, the current miniaturized design lacks a method of pH control. Without pH control, cell growth can be hindered or even stopped altogether when the growing medium becomes too acidic. Using …

The roles and interactions of cations, proteins, and polysaccharides in the settling and dewatering of activated sludge
… acceptable settling and dewatering. Two types of microbial cultures were observed, one required both calcium and magnesium in the feed while the other required either calcium or magnesium, but not both, for optimization of settling and dewatering. Sodium addition to the feed improved the settling …

Controlling dark fermentation of agro-industrial waste for valued organic acids production
… from waste material as feedstock and using mixed microbial cultures (MMC). 2) Critical metal leaching and recovery. Besides PHA production, organic acids produced through DF were used to recover metals from waste from electrical and electronic equipment (WEEE) through leaching process. Electrical …

Rewiring anaerobic digestion: production of biofuel intermediates and high-value chemicals from cellulosic wastes
… the beneficial features of using undefined mixed microbial cultures (also known as microbiomes) for fermentation of heterogeneous organic residues. One of the main identified technological barriers to the carboxylate platform is the inability to control the product spectrum and achieve high …
