Wildan, Ardan; Cheong, Brandon Huey-Ping; Xiao, Kevin; Liew, Oi Wah; Ng, Tuck Wah – Journal of Biological Education, 2020
The provision of hands-on wet lab training for students to perform micro-organism proliferation experiments is useful for experiential skills development. However, the risk of laboratory-acquired infections arising from inadvertent ingestion, inhalation or skin penetration of these micro-organisms presents a safety concern. To obviate this risk,…

Verran, Joanna; Redfern, James; Moravej, Haleh; Adebola, Yvonne – Journal of Biological Education, 2019
A series of events was developed to engage audiences in discussion around the importance of microorganisms in the production of fermented foods, particularly through tasting. The events were designed to attract different audiences: families attending a science museum; families in their community space; and adults in different informal eating…

Nievas, Fiorela L.; Bogino, Pablo C.; Giordano, Walter – Biochemistry and Molecular Biology Education, 2016
Biochemistry courses in the Department of Molecular Biology at the National University of Río Cuarto, Argentina, are designed for undergraduate students in biology, microbiology, chemistry, agronomy, and veterinary medicine. Microbiology students typically have previous coursework in general, analytical, and organic chemistry. Programmed sequences…

Antunes, Patrícia – Journal of Food Science Education, 2016
We proposed in the Basic Microbiology Subject for food science and nutrition students, a "hands-on" activity consisting on sampling student's hands for bacterial presence and identification. This is a project to be implemented in multiple laboratory classes throughout the semester, allowing students to learn, and apply general…

Riley, Erin; Felse, P. Arthur – Chemical Engineering Education, 2017
Centrifugation is a major unit operation in chemical and biotechnology industries. Here we present a simple, hands-on laboratory experiment to teach the basic principles of centrifugation and to explore the shear effects of centrifugation using bacterial cells as model particles. This experiment provides training in the use of a bench-top…

Mussi, María 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…

Rehse, Steven J. – Physics Teacher, 2009
Bacteria are ubiquitous in our world. From our homes, to our work environment, to our own bodies, bacteria are the omnipresent although often unobserved companions to human life. Physicists are typically untroubled professionally by the presence of these bacteria, as their study usually falls safely outside the realm of our typical domain. In the…

Song, Pengfei – Journal of Technology and Science Education, 2014
Non-major students taking science courses to fulfill degree requirements may show low interest in traditional lecture-based classrooms. While professors may try to incorporate hands-on activities to the classroom to foster enthusiasm, the development of a low-cost, low-hazard scienitfic activity that engages students can be challenging. Moreover,…

Prasad, Prascilla; Turner, Mark S. – Biochemistry and Molecular Biology Education, 2011
This open-ended practical series titled "Molecular Identification of Unknown Food Bacteria" which extended over a 6-week period was designed with the aims of giving students an opportunity to gain an understanding of naturally occurring food bacteria and skills in contemporary molecular methods using real food samples. The students first isolated…

Hauri, James F.; Schaider, Laurel A. – Journal of Chemical Education, 2009
Sulfate reducing bacteria have been shown to be effective at treating acid mine drainage through sulfide production and subsequent precipitation of metal sulfides. In this laboratory experiment for undergraduate environmental chemistry courses, students design and implement a set of bioreactors to remediate acid mine drainage and explain observed…

Gardner, Grant E.; Jones, M. Gail – American Biology Teacher, 2009
Nanoscale science and engineering are disciplines that examine the unique behaviors and properties of materials that emerge at the size range of 1 to 100 nanometers (a billionth of a meter). Nanobiotechnology is a sub-discipline of nanoscience that has arisen more recently. Nanobiotechnology is already impacting the fields of healthcare and…

Krist, Amy C.; Showsh, Sasha A. – American Biology Teacher, 2007
Evolution is typically measured as a change in allele or genotype frequencies over one or more generations. Consequently, evolution is difficult to show experimentally in a semester-long lab course because most organisms have longer generation times than 15 weeks. In this article, the authors present an experiment to demonstrate and study…

Rea, Shane L.; Graham, Brett H.; Nakamaru-Ogiso, Eiko; Kar, Adwitiya; Falk, Marni J. – Developmental Disabilities Research Reviews, 2010
The extensive conservation of mitochondrial structure, composition, and function across evolution offers a unique opportunity to expand our understanding of human mitochondrial biology and disease. By investigating the biology of much simpler model organisms, it is often possible to answer questions that are unreachable at the clinical level.…

West, Matthew R.; Hanks, Timothy W.; Watson, Rhett T. – Journal of Chemical Education, 2009
Food- and water-borne bacteria are a major health concern worldwide. Current detection methods are time-consuming and require sophisticated equipment that is not always readily available. However, new techniques based on nanotechnology are under development that will result in a new generation of sensors. In this experiment, liposomes are…

Minnerath, Jeanne M.; Roland, Jenna M.; Rossi, Lucas C.; Weishalla, Steven R.; Wolf, Melissa M. – Bioscene: Journal of College Biology Teaching, 2009
Gram staining bacteria is a fundamental technique introduced in general biology and microbiology laboratory courses. Two common problems students encounter when Gram staining bacteria are (1) having a difficult time locating bacterial cells on the microscope slide and (2) over-decolorizing bacterial cells during the staining procedure such that…
