Journal ArticleDOI
Comparison of growth kinetics and phenol metabolizing enzymes of Trichosporon cutaneum R57 and mutants with modified degradation abilities
TL;DR: The results received in these experiments demonstrated that the increased rate of the initial phenol degradation reaction enhanced phenol utilization by cells and vice versa.
Journal ArticleDOI
Phenol utilization by filamentous yeast Trichosporon cutaneum
N. Shivarova,Plamena Zlateva,B. Atanasov,A. Christov,Nadejda Peneva,M. Guerginova,Zlatka Alexieva +6 more
TL;DR: The investigated strain Trichosporon cutaneum shows well expressed capability for metabolizing high concentrations of phenol, utilizing it as the sole carbon source for the growth and development of the population.
Journal ArticleDOI
Biodegradation of phenol by Antarctic strains of Aspergillus fumigatus.
Maria Gerginova,Jordan Manasiev,Husein Yemendzhiev,Anna Terziyska,Nadejda Peneva,Zlatka Alexieva +5 more
TL;DR: Taxonomic identification of three newly isolated Antarctic fungal strains by their 18S rDNA sequences revealed their affiliation with Aspergillus fumigatus, and the rates of phenol degradation in the three strains correlated best with the activity of catechol 1,2-dioxygenase.
Journal ArticleDOI
Efficiency of microbial fuel cells based on the sulfate reduction by lactate and glucose
Svetlana Bratkova,Zlatka Alexieva,Anatoli Angelov,Katerina T. Nikolova,P. Genova,Rosen Ivanov,Maria Gerginova,Nadejda Peneva,Venko Beschkov +8 more
TL;DR: In this article, the influence of lactate and glucose, used as electron donors on the rate of sulfate reduction, electricity generation and microbial communities in anodic chamber of microbial fuel cells, was studied.
Journal ArticleDOI
Kinetic Parameters Determination of the Phenolic Derivatives Assimilation by Trichosporon Cutaneum R57
Plamena Zlateva,Maria Gerginova,Jordan Manasiev,B. Atanasov,Nadejda Peneva,N.D. Dimova,Zlatka Alexieva +6 more
TL;DR: The kinetic parameters characteristic of the growth and degradation capacity of Trichosporon cutaneum R57 strain in relation to o-, m-, p-chlorophenol, o-, o-, n-nitrophenol, p-cresol, and o-,m-, p-, n-, p, nitrophenols are presented in this article.
