Production of surfactant-stable keratinase from Bacillus cereus YQ15 and its application as detergent additive.

Background: With the growing concern for the environment, there are trends that bio-utilization of keratinous waste by keratinases could ease the heavy burden of keratinous waste from the poultry processing and leather industry. Especially surfactant-stable keratinases are beneficial for the detergent industry. Therefore, the production of keratinase by Bacillus cereus YQ15 was improved; the characterization and use of keratinase in detergent were also studied.

Programmed vaccination may increase the prevalence of asthma and allergic diseases.

Background: The prevalence of asthma and allergic diseases has risen in recent decades. The etiology of asthma and allergic diseases has not been entirely elucidated.

Objective: In this study, we investigated the possibility that programmed vaccination in China may have a potential role in asthma and allergic diseases.
