Today we have an article by one of the Aquaculturists' favourite International Aquafeed writers, Elisabeth Mayer, MSc of Biomin. Well-written and informative, this article on improving water and soil in aquaculture ponds quality using enzymes is well worth a read. Full text here.

| English: Pond near Round Wood There are 12,500 ponds in the Sussex part of the Weald alone, many formed through the need for extracting something from the soil, whether marl to fertilise the fields or stones to build the houses or lanes. (Photo credit: Wikipedia) |
Enzymes are biological molecules that catalyze chemical reactions.A living system controls its activity through enzymes. An enzyme is a protein molecule that is a biological catalyst with three characteristics. First, the basic function of an enzyme is to increase the rate of a reaction. Most cellular reactions occur about a million times faster than they would in the absence of an enzyme. Second, most enzymes act specifically with only one reactant to produce products. In enzymatic reactions, the molecules at the beginning of the process, called substrates, are converted into different molecules, called products. Almost all chemical reactions in a biological cell need enzymes in order to occur at rates sufficient for life. Since enzymes are selective for their substrates and speed up only a few reactions from among many possibilities, the set of enzymes made in a cell determines which metabolic pathways occur in that cell.
