The Momela soda lakes consist of seven small, hypersaline, alkaline lakes, situated in the East African rift valley at Arusha National Park, Tanzania. are fed by separate underground water sources with slightly varying mineral contents resulting colour variation and supporting different kinds prokaryotic eukaryotic species. In this study, diversity Actinobacteria surface sediments five Lakes we...

Microorganisms play a vital role in the degradation of organic matters such as Sawdust and woodchips. In this study, Serial dilution method pour plate techniques were used according to microbiological standards. The media nutrient agar, sabouraud dextrose cellulolytic medium identify microorganisms inoculated them into woodchips kept for 30 days at 37oC 25oC. total viable bacterial count ranged...

Nineteen strains of Corynebacterium sensu stricto, 23 received as Corynebacterium equi or Rhodococcus equi, marker cultures of Arthrobacter, Brevibacterium, Bacterionema matruchotii, Cellulomonas flavigena, Kurthia zopfii, Listeria denitrificans, Microbacterium lacticum, Rhodococcus rubropertinctus and 88 representatives of Mycobacterium, Nocardia, Rhodococcus and the 'aurantiaca' taxon were th...

Deconstructing the intricate matrix of cellulose, hemicellulose, and lignin poses a major challenge in biofuel production. In diverse environments in nature, some microbial communities, are able to overcome plant biomass recalcitrance. Identifying key degraders of each component of plant cell wall can help improve biological degradation of plant feedstock. Here, we sequenced the metagenome of l...

Hydrocarbonoclastic bacterial communities inhabiting mangrove sediments were characterized by combining molecular and culture-dependent approaches. Surface sediments were collected at two sampling sites in Guanabara Bay (Rio de Janeiro, Brazil) and used to inoculate in vitro enrichment cultures containing crude oil to obtain hydrocarbonoclastic bacterial consortia. In parallel, in situ mesocosm...

In a previous study we reported for the first time the isolation and characterization ofurate oxidase enzyme from Pseudomonas aeruginosa. In this work we isolated and cloned a 1.350 kilobase DNA fragment that encode a putative urate oxidase gene from the genomic library of P. aeruginosa Ps-x. The nucleotide sequence of the cloned DNA insert revealed an open reading frame that encodes a protein ...

Charges are considered an integral part of protein structure and function, enhancing solubility and providing specificity in molecular interactions. We wished to investigate whether charged amino acids are indeed required for protein biogenesis and whether a protein completely free of titratable side chains can maintain solubility, stability, and function. As a model, we used a cellulose-bindin...
