Maximizing Collagen Yield from Underutilized Lumpfish () Skins by Optimizing Pre-Cleaning and Extraction Methods.

Female lumpfish () are a primary target of commercial fishery for their roe, a substitute for caviar. The remaining carcasses are underutilized rest raw material. The pre-treatment and acid extraction conditions of collagen from lumpfish skins were optimized.

Whole-Genome Sequences of Streptococcus alactolyticus Strain An1F4 and Escherichia coli Strains Ae3A3 and Ae3B3, Isolated from Feces of Domestic Pigs.

Here, we present the genome sequences of a strain of Streptococcus alactolyticus and two strains of Escherichia coli that were isolated from feces samples from domestic pigs in Denmark. The genome sequences contribute to a better understanding of the microbiological processes in the feces and manure of domestic pigs.

Inhibition of urease activity by different compounds provides insight into the modulation and association of bacterial nickel import and ureolysis.

The nickel-dependent urease enzyme is responsible for the hydrolysis of urea to ammonia and carbon dioxide. A number of bacteria produce urease (ureolytic bacteria) and are associated with various infectious diseases and ammonia emissions from agriculture. We report the first comprehensive comparison of the inhibition of urease activity by compounds analysed under the same conditions.

Synergistic Tannic Acid-Fluoride Inhibition of Ammonia Emissions and Simultaneous Reduction of Methane and Odor Emissions from Livestock Waste.

Gaseous emissions from livestock production are complex mixtures including ammonia, methane, volatile organic compounds (VOC), and HS. These contribute to eutrophication, reduced air quality, global warming, and odor nuisance. It is imperative that these gases are mitigated in an environmentally sustainable manner.

Development of a M9-based urea medium (M9U) for sensitive and real-time monitoring of ureolytic activity of bacteria and cell-free urease.

The enzyme urease is widespread in nature and catalyzes the hydrolysis of urea to form ammonia and carbonic acid. The high proficiency of the enzyme is associated with a wide range of societal challenges. In agriculture, bacterial urease activity leads to loss of fertilizer through NH emission, which has a negative impact on the environment and human health.
