BACKGROUND The commensal intestinal microflora has important metabolic and perhaps also immune modulatory functions. Evidence has accumulated that the microflora plays a role in the pathogenesis of inflammatory bowel disease. Therefore, there is a growing interest in the intestinal microflora and its interaction with the host. Presumably, this interaction takes place at the mucus layer. In this...

reaction constants and heat release during thermophilic aerobic digestion of typical secondary and mixed sludges were determined. maximum reaction constant, determined by measuring the amounts of biodegradable volatile suspended solids (bvss) removed, occurred in the temperature range of 55-60 ºc. measurement of heat releases were carried out, at the same range, by the aid of a temperature prog...

results all 90 campylobacter isolates confirmed by m-pcr were successfully typed using flaa-pcr-rflp. eleven different types were defined according to flaa-typing method and the rflp patterns were located at three separate clusters in rflp image analysis dendrogram. conclusions campylobacter jejuni isolates significantly showed more variety than c. coli isolates. a relatively low genetic divers...

The effect of seeding on the thermophilic composting of sewage sludge was examined by measuring the changes in CO2 evolution rates and microbial numbers. Although the succession of thermophilic bacteria and thermophilic actinomycetes clearly reflected the effect of seeding, no clear difference was observed in the overall rate of composting or quality of the composted product.

INTRODUCTION Protein thermostability is an important field for its evolutionary perspective of mesophilic versus thermophilic relationship and for its industrial/ therapeutic applications. METHODS Presently, a total 400 (200 thermophilic and 200 mesophilic homologue) proteins were studied utilizing several software/databases to evaluate their amino acid preferences. Randomly selected 50 homol...

Since genetically engineered animal models of inflammatory bowel disease (IBD) do not develop colitis under germ-free conditions, the intestinal microflora is thought to be one of the most important environmental factors associated with IBD. To understand the involvement of intestinal microflora in the pathogenesis of IBD, we analyzed the constituents of intestinal microflora in IBD. Faecal sam...

The increasing sophistication in instrumentation, the implementation of powerful genetic techniques and the use of ribosomes of halophilic and thermophilic bacteria have resulted in major accomplishments which could not be foreseen earlier. Most of the recent studies are reviewed in three volumes of Biochemie, two of which are dedicated to the late HG Wittmann and one to A Spirin' s retirement,...

The most intensive study of the aerobic sporeforming bacteria (Smith et al., 1952) has revealed the lack of a clear-cut distinction between thermophilic and mesophilic species of the genus Bacius. It was found, however, that of the many cultures studied, only those belonging to the species BaciUlus stearotenwophilus would grow at 65 C. Some cultures of Bacillus coagulans, Bacius subtilie, Bacil...

endophytes are considered as an important source of bioactive natural products because thesemicroorganisms are able to occupy unique biological niches and grow in non-ordinaryenvironments. therefore, endophytic fungi of medicinal plants can be developed for medicinalapplications. on the other hand, medicinal properties of plant can be ascribed to its endophyticfungi. thymus sp. is widely used a...
