The invention relates to a microbial composition used in the organic
agriculture practice and to a process for preparing the mentioned
composition. According to the invention, the product is represented
by a microbial composition based on antagonistic viable microorganisms
immobilized in bio-polymeric matrices, consisting of
10...15 parts of pre-jellified bio-polymeric matrix, 0.5...3 parts of
concentrated aqueous suspension of viable microbial cells, 1...5 parts
of emulsifier, 0.1...0.5 parts of milk powder as stabilizer, nutritive
and antioxidant supplement, the parts being expressed by weight.
According to the invention, the process consists of three main stages
of processing the bio-materials, namely: hydrothermal prejellification
of bio-polymers, at temperatures ranging between
80...100°C, the emulsification of the useful aqueous micro-organism
suspension and the determination of the suspension-emulsion by jellimmobilization,
with the maintenance of the comfort parameters of
the viable cell: the temperature ranging between 25...60°C, pH
ranging between 6.8...7.5. The product of the invention can be
formulated as a gel, paste, wetable powder, granules, pellets or can
be used as inoculum on lignocellulosic absorbent substrates for the
manufacture of repressive mulch needed for nutrition and protection
crops in conservation farming system. This invention has the
advantage of achieving a bioactive microbial composition intended
as controlled release system of active ingredients antagonistic
microbial for crop diseases and pests, using non-toxic, biodegradable,
accessible and inexpensive raw biomaterials from renewable natural
resources.
