Abstract:

Swimming bacteria explore their environment by performing a random walk, which is biased in response to, for example, chemical stimuli, resulting in a collective drift of bacterial populations towards ‘a better life’. This phenomenon, called chemotaxis, is one of the best known forms of collective behaviour in bacteria, crucial for bacterial survival and virulence. Both single-cell and macroscopic assays have investigated bacterial behaviours. However, theories that relate the two scales have previously been difficult to test directly. We present an image analysis method, inspired by light sca

Abstract:

Dynamic behaviour of microbial film and BOD removal characteristics in an aerobic submerged biofilter packed with ceramic balls were investigated. The effects of BOD loading and temperature on the populations of bacteria and protozoa inhabiting microbial film were investigated. It was ascertained that the BOD removal rate by the microbial film was controlled by the bacterial population, while the microbial concentration in the biofilter was due to the growth of protozoa when the temperature and the BOD loading were low. The analysis of bacterial quinone mixtures was successfully applied to ide

Abstract:

Stainless steel is an important material used in many applications due to its mechanical strength and corrosion-resistant properties. The high corrosion resistance of stainless steel is provided by the passive film. Different stainless steels have different alloy elements and surface properties which could have a significant influence on bacterial attachment to the surface and thus might result in different microbial corrosion behaviours. In this study, the effect of adhesion of sulfate-reducing bacteria (SRB) on corrosion behaviour in artificial seawater on different stainless steels was inve

Abstract:

We have investigated the dynamics of a monotrichous bacteria cell near a wall boundary, taking elastic hook flexibility into consideration. Combining theoretical linear stability analysis and direct numerical computations via the boundary element method, we have found that the elastohydrodynamic coupling between the hook elasticity and cell rotational motion enables a stable vertical spinning behaviour like a low-Reynolds-number spinning top. The forwardly rotated flagellum, which generates the force exertion pushing towards the cell body, typically destabilizes the vertical upright position a

Abstract Staphylococcus aureus infections are a growing concern worldwide due to the increasing number of strains that exhibit antibiotic resistance. Recent studies have indicated that some percentage of people carry the bacteria in the nasal cavity and therefore are at a higher risk of subsequent, and more serious, infections in other parts of the body. However, individuals carrying the infection can be classified as only intermittent carriers versus persistent carriers, being able to eliminate the bacteria and later colonized again.

In nature, biofilms are the most common form of bacterial growth. In biofilms, bacteria display coordinated behaviour to perform specific functions. Here, we investigated electrical signalling as a possible driver in biofilm sociobiology. Using a multi-electrode array system that enables high spatio-temporal resolution, we studied the electrical activity in two biofilm-forming strains and one non-biofilm-forming strain. The action potential rates monitored during biofilm-forming bacterial growth exhibited a one-peak maximum with a long tail, corresponding to the highest biofilm development. Th

Bacterial pathogens cause disease in man and animals.

The bacterial products responsible for these five biological requirements are the determinants of pathogenicity (virulence determinants). Current knowledge comes from studies in vitro , but now interest is increasing in how bacteria behave and produce virulence determinants within the infected host.

Many bacteria have developed a possibility to recognise aspects of their environment or to communicate with each other by chemical signals. The so-called Quorum sensing (QS) is a special case of this kind of communication. Such an extracellular signalling via small diffusible compounds (called autoinducers) is known for many bacterial species, including pathogenic and beneficial bacteria. Using this mechanism allows them to regulate their behaviour, e.g. virulence.

Bacteria are capable of sensing and responding to changes in their environment. One of the ways they do this is via chemotaxis, regulating swimming behaviour. The chemotaxis pathway senses chemoattractant gradients and uses a feedback loop to change the bacterial swimming pattern; this feedback loop differs in detail between species. In the present article, we summarize the current understanding of the regulatory mechanisms in three species and how these pathways can be viewed and analysed through the ideas of feedback control systems engineering.

Abstract:

Social interactions can facilitate transmission of microbes between individuals, reducing variation in gut communities within social groups. Thus, the evolution of social behaviours and symbiont community composition have the potential to be tightly linked. We explored this connection by characterizing the diversity of bacteria associated with both eusocial and solitary bee species within the behaviourally variable family Halictidae using 16S amplicon sequencing. Contrary to expectations, we found few differences in bacterial abundance or variation between social forms; most halictid species a

Abstract:

Behaviour during lactation and its relationship with mammary health was investigated in 12 dairy ewes (six with single lambs and six with twins) for 42 d after lambing. Behavioural recordings were made. Samples of teat duct material and of mammary secretion were collected for bacteriological and cytological examination. Ewes performed similar patterns of behaviour as those described in the literature for meat breeds, but with some differences. No negative maternal behaviours were observed; ewes showed reduced “Grooming” and “Sniffing” immediately post-partum. Of 480 duct or secretion samples,

Abstract:

As one of the main non-covalent relations in microbiological-based systems, cell surface hydrophobicity (CSH) can be observed as a relevant parameter for biodegradation capability and suggested bacterial behaviour and biofilm formation during a bioremediation process. On the other hand, the role of ureolytic bacteria in bioremediation has subsequently led to the examination of this bacterial type in different engineering fields. In order to optimize the operating parameters of microbial adhesion to hydrocarbons test (MATH) for ureolytic bacteria, Box-Behnken experimental design was conducted f

Abstract:

Environmental context. The growing use of nanotechnology means that nanomaterials are likely to be released into the environment, and their impact upon microbes, which form the biological foundation of all ecosystems, remains unclear. To understand how nanomaterials might affect bacteria in the environment, the interactions between a commercially-relevant quantum dot and a common soil and water bacterium was investigated. In this case, it was found that these quantum dots are non-toxic to these bacteria, and also that these bacteria do not cause degradation of the quantum dots. This study also
