Nicotine is a major alkaloid in tobacco plants and an addictive component of tobacco products. Some bacteria grow on tobacco plants and have evolved the ability to metabolize nicotine. As part of our microbiology teaching lab, we used minimal media with nicotine as the sole carbon source to isolate nicotine-degrading bacteria from tobacco leaves…

Fungi mostly reproduce through spores that are adapted for airborne dispersal; hence, fungal spores (and fungi) are found virtually everywhere. Fungi can be "friends or foes." Our friends include fungi used in the food and biotech industries, fungi that contribute to the cycling of carbon and nutrients, and those involved in the…

Amidst the COVID-19 pandemic, many colleges shifted to online learning, creating a need for teaching materials that could be deployed in the online setting. A pair of virtual laboratory exercises with a COVID-19 theme were created for first year Biology majors to introduce students to the topics of polymerase chain reaction and gel…

Bacteria, viruses, and other invisible creatures are, in brief, microorganisms. Especially with the onset of the COVID-19 pandemic, the features of microorganisms, their density, and relevant precautions have grown in importance. Knowing the density of microorganisms at school will cause our cleaning habits to change. In this study, efforts were…

This study aims for students to comprehend the beneficial functions of bacteria with the traditional home yogurt leavening activity. Also, it aims to identify alternative concepts related to leavening and contribute to students' home yogurt consumption habits. The study is a case study. The study was conducted with 29 fifth-grade students studying…

Pigments are light-absorbing substances that are abundant in nature, serving roles in coloration, camouflage, mate/pollinator attraction and photosynthesis among higher life forms. Among microbial organisms, pigments can also be found in a wide range of phyla. While some of these pigments function in photosynthesis, namely among algae and some…

We designed an activity-based science curriculum that used Minecraft to support microbiology learning for students enrolled in the Lang Science Program at the American Museum of Natural History (AMNH) in New York City. Minecraft offered an option to consolidate complex science content into digestible activities for modeling concepts and…

Introductory laboratory courses are a standard component of undergraduate science programmes and historically taught using direct instruction/confirmatory lab models. Previous studies have shown that inquiry-based labs enhance student engagement in science courses. However, research on how direct instruction introductory lab courses effectively…

The "'Streptomyces' genetics and secondary metabolism" laboratory course gives an introduction to the versatile soil dwelling Gram-positive bacteria "Streptomyces" and their secondary metabolism. The course combines genetic modification of "Streptomyces"; growing of the strain and protoplast preparation, plasmid…

Course-integrated Undergraduate Research Experiences (CUREs) involve large numbers of students in real research. We describe a late-year microbiology CURE in which students use yeast to address a research question around beer brewing or synthesizing biofuel; the interdisciplinary student-designed project incorporates genetics, bioinformatics,…

Microorganisms (microbes) play essential roles in our lives, although the general media usually focuses on their negative or pathological aspects. Here we describe a collaborative approach between teachers and academics to teach primary school students about microbes in an engaging and diverse way. We introduced microbes, such as bacteria and…

During the Jurassic period (201 million to 145 million years ago), termites up to 15 mm long consumed and recycled vegetation and feces. Since then, termites have evolved into some 3,000 identified species, have colonized every continent except Antarctica, and are major contributors to nutrient cycling and vertebrate food webs (Shaw 2014).…

Easy-to-use classroom resources that support science teaching are always welcomed by time-poor teachers. Ideally these resources should be easy to find, useful and have the flexibility to be incorporated with minimal adaptation into an already full teaching day. Using food in the classroom is certainly not a new idea--especially for primary school…

A single fly RT-PCR protocol has recently been developed to detect the presence of the persistent, horizontally transmitted Nora virus in "Drosophila." Wild-caught flies from Ohio were tested for the presence of the virus, with nearly one-fifth testing positive. The investigation presented can serve as an ideal project for biology…

For many in the school science classroom, the term "microbiology" has become synonymous with "bacteriology". By overlooking other microbes, teachers may miss out on powerful practical tools. This article describes the development of an activity that uses algae and yeast to demonstrate gas cycling, and presents full instructions…
