CSOM is mostly caused by bacteria, but fungi and virus can also be a cause of CSOM. The aerobic microorganisms most frequently isolated in CSOM are Pseudomonas aeruginosa, Staphylococcus aureus, Gram-negative organisms such as Proteus spp., Klebsiella spp., and Escherichia spp., Citrobacter species, Haemophilus influenzae, and Moraxella catarrhalis (Gül et al., 2006; Verhoeff et al., 2006; de M...

The nitrogen cycle describes the processes through which nitrogen is converted between its various chemical forms. These transformations involve both biological and abiotic redox processes. The principal processes involved in the nitrogen cycle are nitrogen fixation, nitrification, nitrate assimilation, respiratory reduction of nitrate to ammonia, anaerobic ammonia oxidation (anammox) and denit...

Burns are one of the most harmful physical and psychological traumas. Infection is the major cause of morbidity and mortality in burns. Infections acquired from hospital or from the patient's own endogenous flora have a significant prevalence after burns. Pseudomonas aeruginosa and Staphylococcus aureus are the most frequent colonizing agents whereas group A beta-haemolytic streptococci are the...

Proteolytic, aminopeptidase, endopeptidase and carboxypeptidase activities of seven strains of rumen anaerobic fungi, selected to represent the fungal population commonly found in the rumen, were investigated in vitro. Whatever the nitrogen source included in the culture medium, a proteolytic activity against the 14C-labelled casein was detected in only one fungal strain. This strain belonged t...

Oligonucleotide primers were designed for the 18S rRNA genes of members of the Neocallimastigales and used in a nested PCR protocol to amplify 787-bp fragments of DNA from landfill site samples. The specificities of the primers were confirmed by phylogenetic analysis of the environmental clone sequences, and this method can therefore now be used to investigate the ecology of the obligately anae...

PURPOSE Root caries is emerging as a significant problem in the middle aged and elderly subjects because of the improving general health conditions, and medical and technological advances. The purpose of this investigation was to assess the prevalence of aerobic and anaerobic bacteria as well as yeasts of Candida genus in root carious lesions in middle-aged and older adults. MATERIAL AND METH...

• -Baker's yeast wastewater is among the severe environmental threat with 29000 mg/L COD. - M. indicus , hiemalis N. intermedia and A. oryzae were grown on wastewater. Fungi reduced total COD of by 36.3%. Fungal biomass has valuable amino acids minerals for aquaculture feed. The effluent remained was anaerobically digested to biogas further remove Baker's production industry generates large qua...

The anaerobic fungus Neocallimastix sp. strain R1 was grown for up to 5 days on a medium containing autoclaved Italian ryegrass hay as the carbon source. Culture supernatants and digested cell walls were harvested at 12-h intervals. Supernatants were analyzed for the fermentation products formate and acetate, and residual cell walls were analyzed for dry-matter and neutral-sugar losses. Fungal ...
