The "Environmental Microbiology" research group evolved in 1998 from the former Department of Microbiology. The origin of the latter is obscure. It is assumed that during the formation of the Center for Biological Research of Baja California Sur in the late 1970s - early 1980s (the predecessor of present day CIB), the Department naturally evolved as a general microbiological department from the few microbiologists who were staff members of that "baby" research center in the desert, far away from Mexico City. At that time, the Department was involved in countless research projects, regardless of the limited number of staff.
In 1990 the Department of Microbiology was re-structured, limiting the number of research areas to just a few, and made "Plant-microbe interactions" the focal point of its research. For the next 15 years, emphasis in projects was shifted from agricultural-microbiology to environmental microbiology (visit our projects section). In January 1998, the entire departmental structure of CIB was dissolved by the new administration, and the researchers were given the freedom either to form a close association among themselves, or to stay as "individual stars" working alone, a possibility most staff preferred.
One of these few voluntarily associations was the "Environmental Microbiology" Group. In 1999, after several staff shifts, the voluntary group of "Environmental Microbiology" was consolidated. Since 2001, the group agreed to work together on the same objectives and share financial resources and equipment but the group did not have an official facility.
