Werby, Sabrina H.; Cegelski, Lynette – Journal of Chemical Education, 2019
A six-laboratory session biofilm-focused biochemistry laboratory module is described. Through just six four-hour laboratory sessions over three weeks, students first master background knowledge and fundamental experimental techniques to explore questions involving bacterial biofilms at the interface of microbiology and biochemistry and then…

Redelman, Carly V.; Marrs, Kathleen; Anderson, Gregory G. – American Biology Teacher, 2012
In nature, bacteria exist in and adapt to different environments by forming microbial communities called "biofilms." We propose simple, inquiry-based laboratory exercises utilizing a biofilm formation assay, which allows controlled biofilm growth. Students will be able to qualitatively assess biofilm growth via staining. Recently, we developed a…

Candal, Carmen – NCSSSMST Journal, 2012
The effectiveness of five different enzymes as treatments against Staphylococcus biofilm growth was measured in the presence of antibiotics and alone. Protease was the least effective enzyme in biofilm removal with all antibiotics, and pectinase was the most effective with dicloxacillin and clindamycin. Also, dicloxacillin was the most effective…

Redelman, Carly V.; Hawkins, Misty A. W.; Drumwright, Franklin R.; Ransdell, Beverly; Marrs, Kathleen; Anderson, Gregory G. – Biochemistry and Molecular Biology Education, 2012
Inquiry-based instruction in the sciences has been demonstrated as a successful educational strategy to use for both high school and college science classrooms. As participants in the NSF Graduate STEM Fellows in K-12 Education (GK-12) Program, we were tasked with creating novel inquiry-based activities for high school classrooms. As a way to…

Robbins, Chandan Morris – ProQuest LLC, 2012
The objectives of this work are: (1) to agarose-stabilize fragile biofilms for quantitative structure analysis; (2) to understand the influences of LuxS on biofilm formation; (3) to improve teacher quality by preparing Georgia's middle school science teachers to integrate inquiry-based, hands-on research modules in the classroom. Quantitative…

Green, Jennifer H.; Koza, Anna; Moshynets, Olena; Pajor, Radoslaw; Ritchie, Margaret R.; Spiers, Andrew J. – Journal of Biological Education, 2011
Understanding evolutionary mechanisms is fundamental to a balanced biological education, yet practical demonstrations are rarely considered. In this paper we describe a bacterial liquid microcosm which can be used to demonstrate aspects of evolution, namely adaptive radiation, niche colonisation and competitive fitness. In microcosms inoculated…

Lennox, John; Ashe, Jeffrey – American Biology Teacher, 2009
In a climate of increased concern for the environment and its protection, teachers in disciplines as diverse as biology, microbiology, environmental studies, and environmental engineering may be seeking teaching materials and laboratory exercises that will enable them to introduce these new concepts into their classrooms and laboratories. The…

Mussi, MarĂ­a Alejandra; Actis, Luis A.; de Mendoza, Diego; Cybulski, Larisa E. – Biochemistry and Molecular Biology Education, 2014
A laboratory exercise was designed to illustrate how physical stimuli such as temperature and light are sensed and processed by bacteria to elaborate adaptive responses. In particular, we use the well-characterized Des pathway of "Bacillus subtilis" to show that temperature modulates gene expression, resulting ultimately in modification…

Lee, Kilho; Comolli, Noelle K.; Kelly, William J.; Huang, Zuyi – Chemical Engineering Education, 2015
Mathematical models play an important role in biochemical engineering. For example, the models developed in the field of systems biology have been used to identify drug targets to treat pathogens such as Pseudomonas aeruginosa in biofilms. In addition, competitive binding models for chromatography processes have been developed to predict expanded…

Paulino, Tony P.; Andrade, Ricardo O.; Bruschi-Thedei, Giuliana C. M.; Thedei, Geraldo, Jr.; Ciancaglini, Pietro – Biochemistry and Molecular Biology Education, 2004
The main objective of this class experiment is to show the influence of carbon source and of different fluoride concentrations on the biofilm formation by the bacterium "Streptococcus mutans." The observation of different biofilm morphology as a function of carbon source and fluoride concentration allows an interesting discussion regarding the…

Guzman-Armstrong, Sandra – Journal of School Nursing, 2005
Although dental caries in the pediatric and adolescent population has consistently declined in the United States, it is still the most common childhood disease. Dental problems are the number one reason for missing school next to the common cold. Dental caries are an infectious, communicable disease resulting in destruction of tooth structure by…

Anderson, Delia Castro; Hairston, Rosalina V. – American Biology Teacher, 1999
Presents protocols for setting up a Winogradsky column and biofilm slides, interpreting the chemical transformations that occur in the column as a result of color changes in the soil, identifying common microorganisms, and determining the microbial composition of the column over specified intervals of time.

Avant, Thomas – Science Teacher, 2002
This article describes an experiment, designed by Cindy Henk, manager of the Socolofsky Microscopy Center at Louisiana State University (LSU), that involved collecting and viewing microorganisms in the air-water interface. The experiment was participated by Leesville High School microbiology students. The students found that the air-water…
