ABSTRACT The 2011 Vision & Change report outlined several recommendations for transforming undergraduate biology education, sparking multiple pedagogical reform efforts. Among these was the Promoting Active Learning and Mentoring (PALM) network, an NSF-funded program that provided mentorship training to instructors on implementing active learning in classroom. Here, we provide a perspective how members of education community PALM view , drawing upon our experiences both as leaders...

ABSTRACT Improving perceptions of students' science identities and their understanding the nature (NOS) are important learning goals for undergraduate biology students. Previous research has observed that students who reflect on personal histories narratives diverse scientists experience positive changes in own science, respectively. However, these stories were written or mixed media formats (e.g., podcasts, TED talks). Here, we explore whether such nonfiction film, an immersive storytelling...

The aim of this study was to evaluate the activity a novel bacterial laccase-like multi-copper oxidase (LMCO) from Paenibacillus glucanolyticus SLM1: bacterium isolated pulp and paper waste.A new LMCO gene (CuOx) P. SLM1 identified cloned into pET22b. protein it encodes recombinantly expressed in Escherichia coli. recombinant had molecular weight approximately 90 kDa demonstrated oxidation substrates 2,2'-Azino-bis(3-ethylbenzothiazoline-6-sulfonate) (ABTS), catechol, 2,6-Dimethoxyphenol...

Social insects live in dense groups with a high probability of disease transmission and have therefore faced strong pressures to develop defences against pathogens. For this reason, social been hypothesized invest antimicrobial secretions as mechanism external immunity prevent the spread disease. However, empirical studies linking evolution sociality increased investment antimicrobials relatively few. Here we quantify strength among 20 ant species that cover broad spectrum diversity colony...

A citizen science project found that the greenhouse camel cricket ( Diestrammena asynamora ) is common in North American homes. Public response was to wonder ‘what good are they anyway?’ and ecology evolution guided search for potential benefit. We predicted crickets similar household species would likely host bacteria with ability degrade recalcitrant carbon compounds. Lignocellulose particularly relevant as it difficult yet an important feedstock pulp paper, chemical biofuel industries....

Summary The retention (binding to or association with the plant) of E scherichia coli by cut leaves and fruits after vigorous water washing was compared that sprouts. Retention similar but differed from sprouts in rate, effect wounding requirement for poly‐β,1‐6‐ N ‐acetyl‐ D ‐glucosamine. retained ends lettuce within 5 min while more than 1 h required intact epidermis fruits, day at leaf edge specific . not shown plant‐associated bacteria A grobacterium tumefaciens S inorhizobium meliloti....

The kraft process is applied to wood chips for separation of lignin from the polysaccharides within lignocellulose pulp that will produce a high quality paper. Black liquor pulping waste generated by has potential downstream bioconversion. However, recalcitrant nature resources, its chemical derivatives constitute majority available organic carbon black liquor, and basic pH present challenges microbial biodegradation this material. Methods collection modification growth are aimed at...

A. tumefaciens is used in the construction of genetically engineered plants, as it able to transfer DNA plant hosts. Knowledge mechanisms and genes required will aid understanding this process. Manipulation glycoside hydrolases may increase transformation widen host range bacterium. also causes disease (crown gall tumors) on a variety including stone fruit trees, grapes, grafted ornamentals such roses. It possible that compounds inhibit could be control crown caused by .

ABSTRACT Paenibacillus glucanolyticus 5162, a bacterium isolated from soil, and SLM1, pulp mill waste, can utilize cellulose, hemicellulose lignin as sole carbon sources for growth. These two strains of were sequenced using PacBio Illumina MiSeq technologies.

ABSTRACT In this article, we describe curricular materials developed to engage undergraduate students in evolutionary thinking around antibiotic resistance using the MEGA-plate experiment (Microbial Evolution and Growth Arena). This elegant visual experiment, by Kishony Lab, shows development of on timescale hours days. It not only provides important biological insights but also captures students’ attention, making it a very useful tool for education. While short video describing method...

The photosynthetic bioreactor research program is a training platform appropriate for introducing advanced molecular biology techniques to undergraduate students and high school students. For this exercise, the enzyme carbonic anhydrase was cloned, over-expressed, purified, functionally characterized. Carbonic anhydrases are industrially important enzymes with potential use in carbon sequestration biofuel production. Alpha beta from Photobacterium profundum, psychrophilic, halotolerant...

Currently, it is unknown how cortisol fluctuates across a season in female athletes and related to other measures of training load.The purpose this study was 1) evaluate changes salivary Division I collegiate lacrosse (n = 26) 2) assess the relationship between athlete wellness load.Saliva samples were collected biweekly on Monday mornings during first six weeks competitive season.Subjective total scores sub-scores (muscle soreness, sleep quality, fatigue, stress) same days.Objective weekly...

Cellulose is the most abundant biopolymer on planet. Historically rooted in paper industry, advancements colloidal chemistry, polymer and development of novel saccharification techniques have expanded commercial applications cellulose to include production liquid crystal displays, use high strength composites, biofuels. Despite this renewed interest cellulosic products, establishment as a global commodity significantly hindered by inefficiencies liberation processing. The current model...
