Center for Advanced Microbial Processing (CAMP)
The Center for Advanced Microbial Processing's mission is to identify and isolate the genetic components responsible for the generation of the target molecules in non-model organisms and to engineer them for insertion into model bacterial hosts with the ultimate goal being the efficient and cost-effective production of the target molecule.
At the Center for Advanced Microbial Processing we will work toward our goals through interactions between three state-of-the-art facilities:
- A next-generation sequencing center (led by Dr. Garth Ehrlich) which will allow for mining of microbial genomes, metagenomes and hologenomes that we identify as producers of target molecules
- A biochemistry and proteomics analysis laboratory (led by Dr. Joris Beld), which will allow for screening, identification, analysis and purification of target molecules
- A microbial engineering lab for the cloning of genes of interest and the efficient production of target molecules
Antibiotic pipelines in industry are drying up, and more and more pathogens are emerging with resistance to our current treatments. The goal of the Center for Advanced Microbial Processing (CAMP) is to tackle this problem by using microbes as both a source and a tool for the discovery and production of therapeutic agents and novel biologicals.
Nature is extremely efficient at producing complex molecules from very simple starting materials. For example, plants and algae turn sunlight and CO2 into many diverse molecules, including DNA, RNA, proteins, sugars and lipids. Other microbes like many bacteria utilize simple sugars (e.g., glucose) as their food source. Humans have also learned how to make many of these complex molecules synthetically in the laboratory, however the costs and effort can be staggering. Allowing microbes make these molecules for us is the founding principle of biotechnology. This process only requires food for the microbe (e.g., sugar for bacteria), which provides us the product relatively inexpensively. On top of that, bacteria can be fermented at high densities and growth rates, making this biotechnological process fast and efficient.
This approach has only been commercialized in a few cases, often because the underlying biochemistry and microbiology of the microbe is not well understood. For example, in some cases the product itself can be food for the bacteria and thus will be eaten before we can isolate it. Sometimes the product is toxic to the producer. In other cases, regulatory elements can prohibit overproduction or there is simply not sufficient intermediate substrate present in the cell for product formation. These are just a handful of the challenges in designing a microbial platform for rapid, high-yield production of high-value products, like biofuels, medicines or building blocks for the chemical industry.
In order to solve many of these hurdles, researchers have ushered in an era of "metabolic engineering" or "synthetic biology." In this process, we first gain genomic, proteomic and metabolic insight from the bacteria, so that we can build a model of the bacteria in silico. This model describes all the genes, proteins and metabolites in the bacteria and allows us to define metabolic bottlenecks beforehand. With surgical precision we can then edit the genome of the bacteria to remove these hurdles, by insertion of extra genes or deletion and mutation of existing genes. In the end, the goal is to custom design a bacterial strain that produces the desired product in greater amount and faster the original progenitor strain. Engineering the biosynthetic clusters responsible for the production of high-value molecules (e.g., novel drugs) into hosts that are easier to grow is the holy grail of modern metabolic engineering.

On March 31, 2021, Haley Majer successfully defended her PhD thesis entitled “Natural Product Discovery of Thiopeptide Producers and Functional Characterization of Adenylation-Domains in Thiostrepton and Siomycin Biosynthesis.”
August 2020 Karabots Junior Fellows Outreach Initiative
Department of Microbiology and Immunology students and staff have completed another outreach initiative with The College of Physicians of Philadelphia Karabots Junior Fellows. The Junior Fellows are high school students and Philadelphia residents with an interest in health care or medicine, who will be the first in their immediate family to graduate with a higher education degree, and who qualify for free or reduced lunch. The graduate students designed and implemented a three-session program that discussed the need for a cohesive and well-planned national pandemic strategy. The discussions focused on: the role of health care providers and epidemiologists; biostatistics and the creation of databases; the role of biomedical researchers in targeted therapies and vaccine development; and the need for honest and scientifically correct communications between those working to mitigate a pandemic as well as dissemination of information to the public. Participants included Dr. Mary Ann Comunale, Jennifer Conners, Elijah Davis Rachael, Erlich Mohamed Hager, Dr. Ogan Kumova, Teresa LuPone and Kayla Socarras.

August 2019: Lying inside a freezer in Drexel’s College of Medicine are 500 dead, mourned by no one. The deer ticks, dog ticks, lone star ticks and other tiny parasites in the diminutive morgue traveled from nearly every state in the country to reach this resting place. They arrived in baggies or cookie tins or what-have-you, scooped from meadows and forests by helpful volunteers responding to a “call for specimens” on Drexel’s website that was posted by Kayla Socarrás, a doctoral student studying microbiology and immunology. Each tick contains multitudes of smaller organisms — a grab-bag of the pathogenic bacteria that make tick bites so hazardous. Read more.
