Methods: A survey was conducted in an enterprise using a self-designed questionnaire to investigate the general information on enterprise, occupational history of each employee, awareness of occupational health knowledge, awareness of general health knowledge, awareness of hypertension, acquired immune deficiency syndrome, etc., lifestyle, and needs for health knowledge.

Identification and characterization of a novel fumarase gene by metagenome expression cloning from marine microorganisms.

Background: Fumarase catalyzes the reversible hydration of fumarate to L-malate and is a key enzyme in the tricarboxylic acid (TCA) cycle and in amino acid metabolism. Fumarase is also used for the industrial production of L-malate from the substrate fumarate. Thermostable and high-activity fumarases from organisms that inhabit extreme environments may have great potential in industry, biotechnology, and basic research.
