Surface Sampling Methods for Bacillus anthracis Spore Contamination

open access: yesEmerging Infectious Diseases, 2002
During an investigation conducted December 17–20, 2001, we collected environmental samples from a U.S. postal facility in Washington, D.C., known to be extensively contaminated with Bacillus anthracis spores.

Quartz crystal microbalance use in biological studies [PDF]

open access: yes, 1972
Design, development, and applications of quartz crystal microbalance are discussed. Two types of crystals are used. One serves as reference and other senses changes in mass.

Sediment‐Resistant Marine Antifouling Coating Based on Amphiphilic Copolymer Brushes Bearing Sulfobetaine and Isobornyl Pendants

open access: yesAdvanced Materials Interfaces, EarlyView.
Amphiphilic copolymer coatings comprising sulfobetaine methacrylate (SBMA) and isobornyl methacrylate (IBMA) are reported, synthesized via SI‐ATRP, that resist biological fouling and sediment accumulation. The copolymer coating with an SBMA:IBMA feed molar ratio of 1:1 is optimal for reducing diatom adhesion and sediment adsorption.

Lyophilized spore dispenser [PDF]

open access: yes, 1973
A lyophilized spore dispenser is provided which produces a finely divided, monoparticulate cloud of bacterial spores. The spores are contained within a tightly sealed chamber, and a turbulator orifice connected to an air supply source provides a jet of ...

Management of plant health risks associated with processing of plant-based wastes: A review [PDF]

open access: yes, 2009
The rise in international trade of plants and plant products has increased the risk of introduction and spread of plant pathogens and pests. In addition, new risks are arising from the implementation of more environmentally friendly methods of ...

Shaping Microbial Motion with Light: A Contactless Approach Using Diffusioosmotic Flow

open access: yesAdvanced Materials Interfaces, EarlyView.
Light‐controlled, contactless manipulation of cyanobacteria using photoresponsive azobenzene surfactants. Reversible photo‐isomerization generates surface flow, enabling precise trapping, relocation, and directional control of single cells or ensembles with adjustable light intensity and wavelength for noninvasive, spatiotemporally resolved microbial ...

Unravelling the Functional Diversity of Type III Polyketide Synthases in Fungi

open access: yesAngewandte Chemie, EarlyView.
Type III polyketide synthases (T3PKSs) produce diverse compounds of ecological and clinical importance. Here, the activity of 37 fungal T3PKSs was profiled, revealing unexpected products and generating several pharmaceutical precursors. The machine learning model trained on the activity data accurately extrapolates the predictions to other enzymes and ...

Enhanced self-healing capacity in cementitious materials by use of encapsulated carbonate precipitating bacteria : from proof-of-concept to reality [PDF]

open access: yes, 2013
In this study, two bacteria-based self-healing systems were developed for the proof-of-concept and approach to a realistic self-healing. A self-healing system with glass capillaries and silica sol gel carried bacterial cells was first built.
