This study aims to determine suitable start-up conditions and inoculum sources for thermophilic anaerobic digestion. Within days of incubation MSW at 55°C, methane was produced at a high rate. In an attempt to narrow down which components of typical MSW contained the thermophilic methanogens, vacuum cleaner dust, banana peel, kitchen waste, and garden waste were tested as inoculum for thermophi...

Microbial diversity in a thermopilic UASB reactor producing biogas from palm oil mill effluent (POME) was investigated. The PCR-based DGGE analysis showed that the microbial population profiles changed with the temperature transition from mesophilic to thermophilic conditions. Acetotrophic and hydrogenotrophic methanogens were found in all three phases: the seed sludge, transition from mesophil...

Thermophilic fungal cellulases are promising enzymes in protein engineering efforts aimed at optimizing industrial processes, such as biomass degradation and biofuel production. The cloning and expression in recent years of new cellulase genes from thermophilic fungi have led to a better understanding of cellulose degradation in these species. Moreover, crystal structures of thermophilic fungal...

Airborne contamination by thermophilic actinomycetes, micromycetes and Gram negative bacteria was determined on 34 dairy farms and related to fodder drying and storage methods. Eighteen farms had a barn drying system, eight with additional heating; the remaining 16 had traditional fodder storage methods. Three air samples were obtained for each farm with a six stage Andersen sampler. The thermo...

In general, the meat contains nutrients of high biological value and susceptible to contamination by enteropathogens. One way minimizing/eliminating this is use food additives, in case meat, usually sodium sulphite. This technological resource used inhibit growth pathogenic bacteria such as Salmonella spp. thermotolerant coliforms, mandatory parameters foreseen sanitary legislation. Therefore, ...

California’s beach water quality monitoring programs are the most comprehensive in the nation. State Health Services regulations implemented in response to California Assembly Bill 411 require measurement of three indicator bacteria (total coliforms, fecal coliforms and enterococci) on at least a weekly basis at high use beaches. Regulations further require that the public be warned of possible...

Rectal swabs were taken from healthy household dogs that, insofar as could be determined, had not received antimicrobial drugs. Tetracycline-resistant coliforms comprised 80 to 100% of the total number of coliforms in 61 (65%) of the 94 dogs sampled. The median number of other resistance determinants possessed by these tetracycline-resistant coliforms was 5.1. Of the tetracycline-resistant stra...

The bacteriostatic activities of monoacyl sugar alcohols with different acyl chains and hydrophilic heads were examined against some thermophilic sporeformers. Monomyristoyl erythritol and xylitol efficaciously suppressed their spore development. The number and orientation of the hydroxyl groups also played important roles in this activity, and monomyristoyl xylitol exhibited the highest activi...

The primary objective of this study was to assess the antibacterial sensitivity pattern of Coliforms isolates from clinical and sub-clinical mastitis to quinolones. Forty coliforms isolates from bovine clinical and subclinical mastitis were tested for antimicrobial susceptibility by measuring MIC by Resazurin dye broth microdilution method. Of the 27 E. coli isolates tested, only 7.4% of the is...
