Optimization of cellulase production for Bacillus sp. and Pseudomonas sp. soil isolates

This investigation deals with optimizing the cellulase producing bacterial isolates for better enzyme yield. Cellulose degrading bacteria were isolated from garden soil (Aurangabad, MS, India). Amongst 40 different bacterial isolates, two of the bacterial isolates, 2b and 38b, were processed for preliminary identification with morphological, cultural and biochemical characterization. Based on these studies, strain 2b...

Antibiotic resistance of Enterococci isolated from raw camel milk in the South West of Algeria

Little information is available on the diversity and distribution of resistance and virulence factors in Enterococci isolated from camel milk. In this study, 33 samples of camel’s milk collected from the south west region of Algeria were analyzed for the presence of Enterococcus spp. Twenty three (23) enterococcal isolates were recovered. These strains were identified by the API 20 STREP and the sodium dodecyl...

Toxin gene profile and antibiotic resistance of Staphylococcus aureus isolated from clinical and food samples in Egypt

The antimicrobial sensitivity, toxin profiles, and agr genotyping of 70 Staphylococcus aureus isolates were determined. The evaluation of 10 antimicrobials showed that 88.5, 52.8, 40, and 25.7% of isolates were resistant to ampicillin, tetracycline, cefoxitin, and oxacillin, respectively. All isolates were sensitive to gentamicin. The prevalence of staphylococcal enterotoxin (SE) genes (sea, seb, sec, sed, see, seg,...

Morphoagronomic and productive traits of RR® soybean due to inoculation via Azospirillum brasilense groove

In the last decades, the Brazilian soy productive chain has passed through a transformation process in which the yield, efficiency, profitability, economic and environmental sustainability are very important issues. In this context, the introduction of microorganisms has provided an increase in grains yield. The objective of this study was to evaluate the inoculation of Azospirillum brasilense associated with...

Microbiota of freshwater catfish species, Filhote (Brachyplatystoma filamentosum) and Dourada (Brachyplatystoma rousseauxii) from the Amazon Region (Belém-Pará-Brazil)

This paper identified the bacterial flora composition and its influence on the microbiological spoilage process in economically important fish species: Filhote (Brachyplatystoma filamentosum) and Dourada (Brachyplatystoma rousseauxii) in the Amazon region. Microbiological characterization was performed: counts of total mesophilic aerobic bacteria, psychrotrophic bacteria and coliforms at 35 and 45°C, respectively....
