In most habitats, microbial life is organized in biofilms, three-dimensional edifices sustained by extracellular polymeric substances that enable bacteria to resist harsh and changing environments. Under multispecies conditions, bacteria can benefit from the polymers produced by other species ("public goods"), thus improving their survival under toxic conditions. A recent study showed that a Ba...

Over the course of more than a century of laboratory experimentation, Bacillus subtilis has become "domesticated," losing its ability to carry out many behaviors characteristic of its wild ancestors. One such characteristic is the ability to form architecturally complex communities, referred to as biofilms. Previous work has shown that the laboratory strain 168 forms markedly attenuated biofilm...

conclusions the present study suggests that the enzyme obtained from strain b. subtilis can be used as feed supplement in animal diet also for reduction of phosphorus pollution problem in areas of livestock production. materials and methods the present study was conducted in biotechnology laboratory, motilal nehru national institute of technology, allahabad, uttar pradesh, india. to isolate phy...

background: bacillus subtilis refers to stretched and sometimes curved, gram-positive, aerobic, and catalase-positive bacilli, which has thermo-resistant endospores. it has been known as a normal flora in the human but can be pathogens in the case of opportunistic. also, it can be the pathogen of nosocomial infections such as wound among hospitalized patients. purpose of this study was to ident...

Bacillus subtilis YB8 produces the lipopeptide antibiotic plipastatin. B. subtilis MI113, which is a derivative of strain 168, was converted into a new plipastatin producer, strain 406, by competence transformation with the chromosomal DNA of YB8. Transposon mini-Tn10 insertional mutagenesis was applied to strain 406, which revealed that lpa-8 (sfp) (encoding 4'-phosphopantetheinyl transferase)...

Plasmid pPL1010 is a 7.0-kilobase derivative of plasmid pUB110 that harbors the cohesive end site of the bacteriophage SP02 genome. Plasmid pPL1017 is a 6.8-kilobase derivative of plasmid pC194 that contains the immunity region of bacteriophage phi 105 and the cohesive end site of bacteriophage SP02. These plasmids are transducible by bacteriophage SP02 at a frequency of 10(-2) transductants pe...

Exogenous 3-hydroxybutyrate can be utilized by a variety of soil bacteria as a carbon and energy source. However, the membrane transporter responsible for 3-hydroxybutyrate uptake remains unidentified. The Bacillus subtilis strain 168 gene yxjC (herein renamed hbuT) encodes a putative gluconate transporter GntT-type membrane transporter with a previously unknown function. hbuT is organized with...
