The Purpose

Watch your thoughts, for they become words.
Watch your words, for they become actions.
Watch your actions, for they become habits.
Watch your habits, for they become character.
Watch your character, for it becomes your destiny.

— Frank Outlaw

Every blog has a purpose. For some it is to share one's personal life. For others it is to spread a political ideology. I have been blessed with the opportunity to listen to many different minds in science and talked to many whose conviction is that the path forwards in humanity requires us to rethink everything we have done up to this point in order to make sure that future generations survive.

I have decided to dedicate my life to the service of this cause. I know I am not all-knowing nor claim to be. In all humility, keeping in mind the above quote, the purpose of this blog shall be to summarize and share information related to science, biotechnology, and the environment that I find interesting, and engage in an informed, reasoned discussion with anyone willing to learn. I look at this blog as a starting point to change my destiny.

Focus on Algae - Part I: Bioremediation

After spending the last few blog posts on different aspects of dissimilatory bacteria, I want to switch the focus to a different class of organisms I have been interested in for a long time now. These are the algae. Algae comprise a large diversity of "sea weeds" and an even larger variety of single-celled organisms that mostly are capable of doing photosynthesis. They include the ordinary sea-weed, and make up a portion of the green slime found around the edges and the bottom of a pond. More exotic types of algae can live symbiotically - that is together with another organism in a mutually beneficial way. Lichens are an example of symbiotic relationship between algae and fungi. More information about the evolution and lineage of algae can be found in this wiki article.

Typically, these organisms are either not mentioned at all or only in conjunction with toxic algal blooms. But lately, algae, of course, have been in the news recently because of the promi…

Journal Club:”Direct Exchange of Electrons Within Aggregates of an Evolved Syntrophic Coculture of Anaerobic Bacteria” - OR: How Bacteria Hook up to Share Energy

Another curious observation made the science rounds the past week: wired, electric bacteria. Reading this article reminded me of a review article on dissimilatory bacteria I read before, and one of the most interesting talks I ever attended in my life titled "Eavesdropping on Bacterial Conversations".

What did they do?


Summers, who is Microbiologist working in the Lovley lab at the University of Massachusetts, was studying Fe(III) reducing bacteria in the soil. They wondered what would happen when Fe(III) reducing bacteria would deplete Fe(III) available in the soil. In order to study this question, the research group co-cultured two strains of geobacter bacteria: Geobacter metallireducens and Geobacter sulfurreducens. The research team thought that combining the former bacteria that can oxidize ethanol in order to obtain energy, but normally must pass obtained electrons onto Fe(III) which was not present in the solution, with the latter strain which cannot metabolize, but c…
