Dilute Acid Immersion as a Method of Cleaning Shell Eggs

Enrichment of fish eggs with ascorbic acid

Success in aquaculture depends on the mass production and quality of juveniles. However, many fish species suffered high losses during the early stages of development. Therefore, in order to decrease mortality, produce a large number of healthy larvae is a fundamental issue. On the other hand, one of the micronutrients that can be effective in larvae health is ascorbic acid. During the embryoni...

Removal of air ammonia in a spray tower by dilute sulfuric acid solution

Introduction: Workplace air quality is a very important factor in community health and is measured by measuring and evaluating airborne contaminants. One of these airborne pollutants is ammonia gas. Spray towers are important components of air pollution control. The aim of this study was to investigate the effects of using diluted sulfuric acid solution on the efficiency of ammonia removal in a...

Recovery of Salmonella from commercial shell eggs by shell rinse and shell crush methodologies.

Salmonella is the most important human pathogen associated with shell eggs. Salmonella Enteritidis is the serotype most often implicated in outbreaks, although other serotypes have been recovered from eggs and from the commercial shell egg washing environment. Many sample methods are used to recover microorganisms from eggshells and membranes. A shell rinse and modified shell-and-membrane crush...

Dilute Acid Hydrolysis of Papain

Studies on the amino acid sequence of papain by means of the that hydrolysis of endopeptide linkages in dilute acid might peptides from the chymotryptic (l-3) and tryptic digests (4, 5) proceed predominantly by a mechanism, independent of hydrogen of the protein have yielded a considerable number of partial ions, involving un-ionized P-carboxyl groups of aspartyl residue. sequences. Four of the...
