The Spring 2016 Biology Seminar Series continues with Dr. Gargi Kulkarni's talk: Bacterial hopanoids and their role in plant symbiosis
Symbiosis means "living together”, i.e. when two organisms live in close association to benefit each other. For instance, soil bacteria called rhizobia, like Bradyrhizobium diazoefficiens, can enter into symbiosis with leguminous plants, like soybean. In this relationship, the plants provide the bacteria with a food source and the bacteria provide the plant with the essential nutrient nitrogen. Our recent research suggests that hopanoids or cholesterol-like lipids produced by rhizobia are required for proper growth of bacteria in both free-living soil and symbiotic plant states. More research into how hopanoids help bacteria to survive may aid in engineering of more robust agricultural strains that are resistant to harsher climates.Read More

Participate in the BioBlitz@Oxy event on April 2, 2016
The Bioblitz@Oxy is a citizen science event to document the biodiversity of Occidental College. During this one day event, we will identify as many species as possible on the Occidental College campus. These data will provide baseline knowledge about local biodiversity so we can measure how these species respond to future environmental changes.
To sign up and view more information, please visit the BioBlitz website: http://biodiversity.oxycreates.org/

The 2016 Spring Biology Seminar Series continues with Dr. Michael Wagner's talk: Nitrification 2.0: The discovery of Comammox bacteria in terrestrial and freshwater habitats
We love to study the hidden world of microbes and are particularly excited to investigate microbes directly in their natural environment. My team is interested in many aspects of the nitrogen cycle. Bioavailable nitrogen is essential for all organisms and is the main limiting nutrient for life on our planet. The process of nitrification — the oxidation of ammonia to nitrate by way of nitrite — links the gain and loss of bioavailable nitrogen and thus plays a central part in the nitrogen cycle. Since the first description of nitrifying microbes more than 100 years ago by Sergei Winogradsky nitrification was thought to be conducted by the joint activity of two groups of microorganisms. We recently discovered that complete nitrifiers exist that can oxidize as single...Read More
