Limited information is currently available on the contribution of eukaryotes to the reactor performance of membrane bioreactors (MBRs). Using high-throughput Illumina sequencing of 18S rRNA genes and microscopic observations, we investigated eukaryotic microbiomes in membrane-attached biofilms in MBRs treating piggery wastewater. Protozoa preying on bacteria were frequently detected under stabl...

Reverte oxo-biodegradable additive masterbatch and bags are not compliant to the criteria stated in AS4736 which is an Australian Standard® Biodegradable plastics—Biodegradable plastics suitable for composting and other microbial treatment documents. Well Plastics UK are in the same opinion as the Oxo-biodegradable Plastics Association that bio-based is the wrong technology (reason is as attach...

Microbial life manifests itself in complex communities such as the ones attached to plant surfaces. They consist of beneficial mutualists and epiphytes as well as of potential pathogens. Plants express surface receptors that recognize them according to their microbe-associated molecular patterns (MAMPs). MAMP-stimulated plant responses have been studied for a long time. Recently a number of rep...

Acidophilus PearlsTM is a probiotic dietary supplement designed to help support digestion and a healthy intestinal system. Probiotics, such as Lactobacillus acidophilus and Bifidobacterium longum are live microbial food supplements that are non-toxic and do not cause disease (non-pathogenic). Probiotics do not permanently colonize in the body. Therefore, they need to be ingested regularly for t...

When attached to surfaces, aggregated microorganisms (predominantly bacteria) and their extracellular polymeric substances are commonly known as biofilms. They are ubiquitous in nature and its formation is part of a strategy that bacteria use in order to survive in hostile environments. Although biofilms play crucial roles in many processes (biodegradation of environmental pollutants or the mic...

A new species of Archaea grows at pH approximately 0.5 and approximately 40 degrees C in slime streamers and attached to pyrite surfaces at a sulfide ore body, Iron Mountain, California. This iron-oxidizing Archaeon is capable of growth at pH 0. This species represents a dominant prokaryote in the environment studied (slimes and sediments) and constituted up to 85% of the microbial community wh...

Pure cultures of termite gut spirochetes were obtained and were shown to catalyze the synthesis of acetate from H2 plus CO2. The 16S ribosomal DNA sequences of two strains were 98 percent similar and were affiliated with those of the genus Treponema. However, neither was closely related to any known treponeme. These findings imply an important role for spirochetes in termite nutrition, help to ...

In this paper, we drive the concentration of microbial growth in groundwater system. This model is based on system non-linear differential equations. The equations solved by using new homotopy perturbation method. We followed toluene degradation and bacterial measuring oxygen concentrations direct cell counts. And total amount degraded Pseudomonal putida F1 sediment columns increased with risin...

BACKGROUND AND AIM: An important goal of periodontal plastic surgery is the creation of attached gingiva around the teeth. In this study, the aims were to culture gingival fibroblasts in a biodegradable scaffold and measure the width of attached gingiva after the clinical procedure.METHODS: This study was carried out on 4 patients (8 sites), with inadequate attached gingiva next to at least two...

Abstract Biofilm is the most successful and widely distributed form of life on earth, it not simply structured collections cells attached to surfaces but a dynamic complex biological system able respond environmental changes. The biofilm characteristics make unique central microbial evolution adaptation. ability establish biofilms key trait for microorganisms growing in extreme environments lik...
