Article Synopsis
- A two-year study was conducted in Qingdao from November 2018 to January 2020 to analyze trace elements in atmospheric particulate matter (PM) during autumn and winter, focusing on their sources and health risks.
- The research identified four air quality levels and revealed that concentrations of trace elements, particularly vanadium (V), decreased significantly due to the implementation of the Domestic Emission Control Area (DECA) policy aimed at reducing pollution from ships.
- Health risk assessments indicated varying levels of non-carcinogenic and carcinogenic risks associated with elements like manganese (Mn), arsenic (As), and cadmium (Cd), highlighting the need for better pollution management strategies.
Response surface optimization of fermentation conditions for producing xylanase by Aspergillus niger SL-05.
J Ind Microbiol Biotechnol
July 2008
Fermentation conditions were statistically optimized for producing extracellular xylanase by Aspergillus niger SL-05 using apple pomace and cotton seed meal. The primary study shows that culture medium with a 1:1 ratio of apple pomace and cotton seed meal (carbon and nitrogen sources) yielded maximal xylanase activity. Three significant factors influencing xylanase production were identified as urea, KH(2)PO(4), and initial moisture content using Plackett-Burman design study.
