The S1 secondary alkylsulphohydrolase of the detergent-degrading micro-organism, Pseudomonas C12B, was separated from other alkylsulphohydrolases and purified to homogeneity. Under the experimental conditions used the enzyme completely hydrolysed d-octan-2-yl sulphate (d-1-methylheptyl sulphate), but showed no activity towards the corresponding l-isomer. Additional evidence has been obtained to...

Biofilms are structured communities of bacterial cells enclosed in a self-produced polymeric matrix and adherent to an inert or living surface; they have clinical, industrial and environmental impacts. Biofilms that are established by bacteria on plants are found on the surfaces of roots, leaves, seeds and internal vascular tissues where the microbes live in commensal, mutualistic or parasitic/...

On the road towards efficient diagnostics of infectious diseases, sample preparation is considered as the key step and remains a real technical challenge. Finding new methods for extraction of micro-organisms from a complex biological sample remains a major challenge prior to pathogen detection and analysis. This paper reports a new technique for capturing and isolating micro-organisms from a c...

Most exacerbations of asthma can be proven to be associated with bacterial infections and there is scientific evidence that frequent respiratory infections particularly bacterial infections provoke asthma attack. Considering these facts different plant extracts and phytoconstituents with proven anti asthmatic property had been selected for screening anti microbial activity in in-vitro models. I...

This paper describes the motivation behind the adoption of a musification approach to the auditory display of flagella movement (specifically, malaria in the form of P. berghei) as shown in high resolution 3D holography. The criteria applied to the data mapping process in order to achieve this musification are also described, with an approach to spatialization in order to represent three dimens...

Revealing the biochemistry associated to micro-organismal interspecies interactions is highly relevant for many purposes. Each pathogen has a characteristic metabolic fingerprint that allows identification based on their unique multivariate biochemistry. When pathogen species come into mutual contact, their co-culture will display a chemistry that may be attributed both to mixing of the charact...

This article describes the electrical characterization of live and heat-inactivated micro-organisms within microstructures. Electrophoretic movement of live and heat-inactivated Listeria innocua on interdigitated fingered electrodes confirmed the presence of negative charges on the live micro-organisms and demonstrated positive or neutral charges on the heat-inactivated micro-organisms. A micro...

The existence of the spiritual self is a prerequisite for occurrence social process. Without soul and self, human society cannot exist. However, if mind are not produced in process, individual organism have semiotic self. George Herbert Mead’s general method macro evolution combined with some micro themes about biology psychology, which brings together many schools thought, such as cognitive th...
