Development of an asporogenic Bacillus licheniformis for the production of keratinase [PDF]

Journal of Applied Microbiology, 2005
Bacillus licheniformis PWD-1 is a keratin-degrading, spore-forming bacterium isolated from a poultry waste digester. A sporulation-deficient mutant of B. licheniformis PWD-1, named B. licheniformis WBG, was developed and characterized.The mutation was generated using the splicing by overlap extension PCR method (Gene SOEing) to create 256 bp deletion ...

Climate Change, Natural Disasters, and Cutaneous Fungal Infections

International Journal of Dermatology, Volume 64, Issue 8, Page 1349-1355, August 2025.
ABSTRACT Fungal infections are an important source of morbidity and mortality that can manifest as superficial or invasive diseases. Diagnostic techniques for human fungal pathogens remain problematic, and multi‐drug resistance is emerging. This review addresses the potential emergence of new fungal pathogens in changing environments and reported ...

Bacillus sp. FPF-1 Produced Keratinase with High Potential for Chicken Feather Degradation

Molecules, 2020
Chicken feathers are predominantly composed of keratin; hence, valorizing the wastes becomes an imperative. In view of this, we isolated keratinase-producing bacteria and identified them through the 16S rDNA sequence. The process condition for keratinase

Using the Technique for Order Preference by Similarity to Ideal Solution to Determine the Best Level of Hydrolysed Feather Powder in Broilers Diet

Veterinary Medicine and Science, Volume 11, Issue 4, July 2025.
Determination the Best Level of Hydrolyzed Feather Powder in Broilers Diet by TOPSIS Method. ABSTRACT Background Feathers constitute about 5–7 percent of broilers live body weight, and they are bulky waste in poultry slaughterhouses. These wastes are a serious issue that can cause environmental pollution.

Oncogenic Human Papillomaviruses Drive One‐Third of Sinonasal Squamous Cell Carcinoma and Are Not Mutually Exclusive for Gene Mutations

Head &Neck, Volume 47, Issue 6, Page 1726-1735, June 2025.
ABSTRACT Background The detection rate of oncogenic human papillomaviruses (HPVs) in sinonasal squamous cell carcinomas (SNSCCs) varies among studies. The mutational landscape of SNSCCs remains poorly investigated. Methods We investigated the prevalence and prognostic significance of HPV infections based on p16 protein expression, HPV‐DNA detection ...
