Anaerobic bacteria, microbial testing

Microbial testing for aerobic and anaerobic bacteria and fungi is typically conducted. Specific species searched for include ... 

To control the microbiological situation, sometimes a full count of microbe species at different locations is required, rather than determination of the presence of certain microbial groups like sHme-forming species, fungi, yeasts, anaerobic bacteria, etc. Conventional methods for identification of microbes include enumeration and screening of individual species isolated from count plates on selective media. Ready-made plates are available for the selection of different types of microbes. Commercial identification systems for industry and medical purposes, based on numerous biochemical tests or other characteristics, are available, including a database that covers practically aU groups of bacteria. 

The study was carried out on fecal material from 5 treated patients (AD, BD, FC, GM, AC) (Table 1) and from 5 healthy subjects (controls) (AF, AG, GB, GV, FB). The bile acids treatment did not induce gastrointestinal side effects in any patients. The feces, within 2 h of collection, were placed in an anaerobic cabinet (N2 H2 C02 atmosphere, 85 10 5), subjected to bacteriological examination and to tests for biochemical activity on CDA and UDA[1]. The microbial groups examined were anaerobic bacteria, Bacteroidaceae, bifidobacteria, Clostridia, anaerobic cocci, lactobacilli, coliform bacteria, aerobic bacteria. Different media were used[2] and the characterization of isolated strains was performed taking into con-... 

Electrokinetically enhanced bioremediation is an in situ process for the treatment of soils and groundwater contaminated with petroleum hydrocarbons and other compounds easily biodegraded under anaerobic conditions. Bench-scale tests have shown that the apphcation of an electric field provides electrokinetic transport of nutrients and biodegrading bacteria to areas of contamination. In addition, microbial growth is enhanced, nitrate transport can be predicted, and beneficial temperature increases can be achieved to areas of contamination.
