Bacillus subtilis BML5 Isolated from Soil Contaminated with Poultry Waste has Keratinolytic Activity
Aqsa Imtiaz and Abdul Rehman*
...study aim was to isolate keratinolytic bacteria from the soil contaminated with poultry waste. From amongst nine bacterial keratinase producing isolates were found. The BML5 isolate was identified as Bacillus subtilis based on biochemical characterization and 16S rRNA Ribotyping. B. subtilis BML5 showed maximal keratinase activity at 37°C and at pH 8. An increase i...

SEM observations of surface of the radix linguae revealed conical papillae and tongue caudally directed lingual papillae. Thus, in this study, the anatomy and histology of the tongue of the guinea fowl tongue were examined in detail using light and scanning electron microscopy, and the similarities and differe...

The lamina propria didn’t penetrate completely into the filiform papillae of the lateral margin. Numerous forms of lingual salivary glands with seromucous secrations were intermingled with the lingual muscles in the lingual root.
