Interactions between phytoplankton and heterotrophic bacteria have been intensively studied, but many aspects of these interactions are still unknown because most of the studies were performed under non-axenic conditions. Therefore, we investigated the growth and release of dissolved organic matter of the marine diatom Thalassiosira rotula in axenic culture in comparison to T. rotula cultures i...

This study aimed to identify Staphylococcus sp. and antibiotic resistance in Tutur District, Pasuruan. A total of 273 samples cow's milk were evaluated identified as Furthermore, the test was carried out according CLSI standards. showed 41 isolates 97 positive CMT. The results reported seven resistant antibiotics consisted one multidrug-resistant isolate, i.e. S. saprophyticus which penicillin,...

Article history: Received on: 10/07/2012 Revised on: 03/08/2012 Accepted on:23/08/2012 Available online: 28/09/2012 Bacterial are well known for their ability to excrete enzymes into the environment. Bacillus sp. being industrially important organisms produces a wide variety of extra-cellular enzymes including proteases. Bacillus sp. isolated from local marine samples collected from Saudi Arabi...

Nine bacterial isolates from the rhizosphere and(or) tubers of potato (Solanum tuberosum cv. Kennebec) at a field site on Prince Edward Island were assessed as food sources for a bacteria-feeding nematode species tentatively identified as Diplogaster lheritieri. This species was the most common rhabditid nematode recovered from soil around potato roots at the same site. In laboratory feeding tr...

Many bacteria produce secreted virulence factors called exotoxins. Exotoxins are often encoded by mobile genetic elements, including bacteriophage (phage). Phage can transfer genetic information to the bacteria they infect. When a phage transfers virulence genes to an avirulent bacterium, the bacterium can acquire the ability to cause disease. It is important to understand the role played by th...

Peptide tagging is a key strategy for observing and isolating proteins. However, the interactions of proteins with peptides are nearly all rapidly reversible. Proteins tagged with the peptide SpyTag form an irreversible covalent bond to the SpyCatcher protein via a spontaneous isopeptide linkage, thereby offering a genetically encoded way to create peptide interactions that resist force and har...
