Strategies to Foster LatinX Inclusion in Microbiology Programs.

Inclusion is an active, powerful, and emotional noun that over the past years has helped me reconcile my main passions in life: microbiology, teaching, research, and mentoring. Although I am now part of an inclusive excellence family, during my graduate school I always felt alone, like an imposter microbiologist. I want to avoid other Latinas feeling the same way; consequently, I share frameworks and strategies here to foster inclusion in Microbiology departments.

Laboratory activity to effectively teach introductory geomicrobiology concepts to non-geology majors.

We have designed a three-week experiment that can complement any microbiology course, to teach main geomicrobiology concepts for non-geology majors. One of the most difficult concepts for non-geology majors to comprehend is how bacteria serve as a platform for different mineralization reactions. In our three-week laboratory practice, students learn the main principles and conditions required for an induced bacterial mineralization.

Exopolymeric substances (EPS) from Bacillus subtilis: polymers and genes encoding their synthesis.

Bacterial exopolymeric substances (EPS) are molecules released in response to the physiological stress encountered in the natural environment. EPS are structural components of the extracellular matrix in which cells are embedded during biofilm development. The chemical nature and functions of these EPS are dependent on the genetic expression of the cells within each biofilm.

Physiological requirements for carbonate precipitation during biofilm development of Bacillus subtilis etfA mutant.

Although the implications of calcium carbonate (CaCO(3)) precipitation by microorganisms in natural environments are quite relevant, the physiology and genetics of this phenomenon are poorly understood. We have chosen Bacillus subtilis 168 as our model to study which physiological aspects are associated with CaCO(3) (calcite) formation during biofilm development when grown on precipitation medium.

Learning geomicrobiology as a team using microbial mats, a multidisciplinary approach.

Microbial mats are one of the best suited laminar organo-sedimentary ecosystems for students from different educational backgrounds to visualize the direct relationship between microbes and minerals. We have used tropical hypersaline microbial mats from Puerto Rico as educational tools to promote active learning of geomicrobiology introductory concepts for undergraduate students organized in multidisciplinary teams with biological and geological backgrounds. Besides field trips and independent research projects focused on microbial mats, four intensive workshops and one capstone activity were designed to expose students to the different geomicrobiology subdisciplines (microbiology, molecular biology, geology, and geochemistry).

Characterization of fungi from hypersaline environments of solar salterns using morphological and molecular techniques.

The Cabo Rojo Solar Salterns located on the southwest coast of Puerto Rico are composed of two main ecosystems (i.e., salt ponds and microbial mats).
