Detection of Aerobic Bacterial Endospores: From Air Sampling, Sterilization Validation to Astrobiology [PDF]

open access: yes, 2008
Bacterial endospores are formed in genera such as Bacillus and Clostridium in times of incipient stresses. Derivative of their remarkable resistance and ubiquity, endospores are delivery vehicles for anthrax attack, biological indicators for checking ...

Ultrasound-Assisted Fermentation to Remove Cadmium from Rice and Its Application

open access: yesMolecules, 2023
Rice, which is a major part of the daily diet, is becoming more and more contaminated by cadmium (Cd). This study combined low-intensity ultrasonic waves with the Lactobacillus plantarum fermentation method and optimized this technique by a single-factor

Electrochemiluminescence Detection of Methamphetamine in Biological Matrices [PDF]

open access: yesCounterterrorism, Crime Fighting, Forensics, and Surveillance Technologies IV, 2020
We have studied an electrochemical detection method for the stimulants in the forensic samples using electrochemiluminescence (ECL). In this context, amphetamine type stimulant (methamphetamine (MA)) has been studied as co-reactants in the [Ru(bpy)3]2+ (where bpy is 2,2’-bipyridine) ECL system.

Development of a Bioaerosol single particle detector (BIO IN) for the Fast Ice Nucleus CHamber FINCH [PDF]

open access: yes, 2010
In this work we present the setup and first tests of our new BIO IN detector. This detector was constructed to classify atmospheric ice nuclei (IN) for their biological content. It is designed to be coupled to the Fast Ice Nucleus CHamber FINCH.

Algicidal Molecular Mechanism and Toxicological Degradation of Microcystis aeruginosa by White-Rot Fungi

open access: yesToxins, 2020
Current research on the inhibition of Microcystis aeruginosa growth is primarily focused on algae-lysing bacteria, and few studies have investigated the inhibitory mechanisms by which fungi affect it at the molecular level.
