One way of conserving microorganisms is in liquid nitrogen gas cylinders at 196ºC below zero
Embrapa Agrobiology is seeking partners to produce agrochemical bioremediation micro-organisms. 
The Brazilian Agricultural Research Corporation (Embrapa) invested for over four decades in the conservation of bacteria, viruses, fungi, yeast and others. It is now using this material in soil, where there is a persistence of agrochemicals.
“The most efficient biodegradable strains were already identified, the experiments gave good results and, in the moment, we are looking for partners to put this technology in the market,” said Researcher Maria Laura Mattos of Embrapa Clima Temperado.
The expert believes that the technology will arouse the interest of the productive sector, once it attends also the market for organic food. According to data from the National Council of Organic and Sustainable Production, the Brazilian market of organics grew by 20 per cent in 2016, with an estimated revenue of R$3 billion. And the expectation points to an even bigger growth in 2017 at a minimum rate of 10 per cent.
At the Genetic Resources Unit of Embrapa, there are advanced studies for the use of micro-organisms in the biological control of insect-plague and mosquitoes that transmit diseases. The unit has a bank with over 2,600 strains of Entomopathogenic bacterias. 
Among these are products based on fungi, such as Beauveria bassiana, Nomuraea rileyi and Metarzium anisopliae, and virus. There are also biocontrolling fungi of the diseases of plants, among them are the ones that belong to the Trichoderma genre. “We have today a unit in Brasília DF, of over 1,000 lines of these fungi,” said Embrapa Researcher, Sueli Mello.
“It is necessary to take advantage of this positive scenario to insert the technologies of Embrapa in the Brazilian market,” said Mattos. According to her, the biological products represent a big opportunity for innovation and competitiveness in Brazilian agriculture and attend to the environmental perspectives and sustainable use of ecological services.
