History of microorganisms

A few milestones in early mycorrhiza research

1842

Karl Nageli was probably the first person to provide a graphical description of mycorrhiza as well as structures inside root cells similar to the arbuscules.

1852

Theodore Hartig, first to publish the description of a mantle and the mycelia in the intercellular spaces of root cortical cells, the later known as Hartig net, in conifers.

1885

Albert B. Frank was the first to give the name mycorrhiza to the association between tree roots and ectomycorrhizal fungi.

1897

Janse named vesicles to observed spheres inside the roots. In 1905 Gallaud described with detail the mycorrhizal arbuscules.

A.B. Hatch, first evidence of positive correlation between mycorrhizal infection and nutrient mobilization.

1939

Burges suggests that the mycorrhiza could provide some nutrients to the host plant.

Atens is founded as a family business founded, born of a passion for research, and with the main objective of producing mycorrhiza for sustainable agriculture.

1996

Isolation of Rhizoglomus irregulare strain BEG72 in citrus trees by doctors Amelia Camprubi and Cinta Calvet.

2001

After 7 years of research, the first product based on mycorrhiza under the brand AEGIS SYM was launched in 2001. It remains today as the highest quality inoculum available in the market.
