Abstract
Introduction. Environmental pollution produced by the disposal of the serum that results from
dairy industries activities is a motivation for keeping on searching for effective technologies
that allow the use of this sub product. The use of efficient micro organisms usually used to
transform the soil, recovery of agricultural and farming resources and water treatments, can
be an alternative for a company located in the North of Antioquia, Colombia, which produces
great quantities of serum per year and does not have an effective treatment for it, causing
environmental problems.
Objective. To transform mil serum obtained from a dairy company located in the North
of Antioquia by the use of efficient micro organisms, aiming to reduce the contamination
produced by this process remain.
Materials and methods. Efficient micro organisms of the lactobacillus type were applied
to the salty serum produced in a company from the Northern Antioquia region. The serum
was treated at 94°C and the phases formed were separated with a filtration. The initial
and precipitated serums were characterized by the application of physical, chemical and
bromatological analysis procedures.
Result analysis. Efficient micro organisms help to separate two stages: An inferior stage
or precipitation represented by the 7.10%, in which a protein increase is observed (from 0.86±0.04% to 6.58±0.05% after the treatment) due to the hydrogen fixation and concentration
capacity of the micro organisms. The second stage, which takes place at a liquid state, was
characterized in order to determine the reduction of the value corresponding to the chemical
oxygen demand (COD). A 98% measure was achieved.
Conclusion. The use of efficient micro organisms is an alternative for the treatment of serum,
as an organic waste from dairy industries, because it allows the recovery of a phase (7.10%)
which represents a protein increase that can be used for obtaining other products for human
an animal consumption. Besides, an approximately 98% COD removal rate is achieved in the
liquid stage, avoiding an environmental risk.
