The diversity of thermophilic bacteria was investigated in four hot springs, three salt marshes and 12 desert sites in Morocco. Two hundred and forty (240) thermophilic bacteria were recovered, identified and characterized. All isolates were Gram positive, rod-shaped, spore forming and halotolerant. Based on BOXA1R-PCR and 16S rRNA gene sequencing, the recovered isolates were dominated by the g...

Acetaminophen (paracetamol) has been classified as one of the emerging organic pollutants due to its entrance into water bodies. Removal pharma micropollutants using microorganisms or synthetic systems from environment is desirable. In this study, acetaminophen degrading microorganism was isolated Pharmaceutical industrial wastewater. Identification isolate carried out morphological, biochemica...

Acetoin is an important bio-product useful in the chemical, food and pharmaceutical industries. Microbial fermentation major process for production of bioacetoin, as petroleum resources used chemical methods are depleting day by day. Bioacetoin using wild microorganisms easy, eco-friendly economical method bioacetoin. In present study, culture conditions nutritional requirements were optimized ...

We present a computational method for prediction of functional modules that can be directly applied to the newly sequenced microbial genomes for predicting gene functions and the component genes of biological pathways. We first quantify the functional relatedness among genes based on their distribution (i.e., their existences and orders) across multiple microbial genomes, and obtain a gene netw...

Streptococcus cremoris Wg2 plasmid pWV01 was introduced in Bacillus subtilis by protoplast transformation. The yield of pWV01 isolated from B. subtilis was low. pWV01 contains a unique site for the restriction endonuclease MboI.

Background and Objectives: The purpose of the present study was to investigate effects of various heat shock conditions and fast freezing and subsequent thawing on the viability and recovery of Bacillus coagulans and Bacillus subtilis as probiotic sporeformers, and also to compare spore plate and microscopic counts. Materials and Methods: After preparing the final suspensions of B. coagulans an...

polyurethanes (purs) are polymers that can be generated by a step-growth polyadditionreaction of diisocyanates with polyols. the number of well-developed chemical procedures applicable to theirmanufacture, and the diversity of chemical structures in which polyurethanes can be built, account for thewidespread use of these materials in the last few decades for both domestic and technical applicat...

The CryIVD protein is involved in the overall toxicity of the Bacillus thuringiensis subsp. israelensis parasporal inclusions and is one of the four major components of the crystals. Determination of the DNA sequence indicated that the cryIVD gene is the second gene of an operon which includes three genes. The first one encodes a 19-kDa polypeptide and has sequence homology with the orf1 gene o...

abstract background and aims: influenza a(h5n1) viruses  circulating in animals might evolve and acquire the ability to spread from  human to human and thus start a pandemic. hemagglutinin (ha) has been shown to play a major role in binding of influenza virus to its target cell and the main neutralizing antibody responses elicit against this region. recent studies have shown that glycosylation ...
