Airborne micro-organisms: a technique for studying their survival

Investigation of Removal Capacities of Biofilters for Airborne Viable Micro-Organisms

New emerging issues appears regarding the possible aerosolization of micro-organisms from biofilters to the ambient air. Traditional bioaerosol sampling and cultural methods used in literature offer relative efficiencies. In this study, a new method revolving around a particle counter capable of detecting total and viable particles in real time was used. This counter (BioTrak 9510-BD) uses lase...

Acetylation of peptides inhibits their degradation by rumen micro-organisms.

Proteins and peptides were acetylated using acetic anhydride in order to block their N-terminal amino groups and thereby to prevent their hydrolysis by rumen microbial aminopeptidases. The effects of acetylation on peptide breakdown and ammonia production were determined by incubating unmodified and acetylated substrates with sheep rumen micro-organisms in vitro. Ammonia production from casein ...

Micro-Organisms in Water—Their Signification, Identification and Removal

Adaptation in Micro-Organisms

all the humdrum of mental undressing, dressing, shaving, etc., there is the chance reward of being confidential ear to what may never be so well expressed or thought of again. The contributors of the "relatively brief" presentations are six in number. Alex Bavelas talks on "Communication patterns in problem-solving groups"; Ivor A. Richards, on "Communication between men: Meaning and language";...
