We report the main characteristics of 'Actinomyces provencensis' strain SN12T sp. nov., 'Corynebacterium bouchesdurhonense' strain SN14T sp. nov., 'Corynebacterium provencense' strain SN15T sp. nov. and 'Xanthomonas massiliensis' strain SN8T sp. nov., which were all isolated from stool samples from obese French patients.

Many compounds produced by fungi have relevant pharmaceutical applications. The purpose of this study was to collect and isolate endophytic fungi from different regions of Panama and then to test their potential therapeutic activities against Leishmania donovani, Plasmodium falciparum, and Trypanosoma cruzi as well as their anticancer activities in MCF-7 cells. Of the 25 fungal isolates obtaine...

This is an updated paper focusing on the general epidemiological aspects of Rhodotorula in humans, animals, and the environment. Previously considered nonpathogenic, Rhodotorula species have emerged as opportunistic pathogens that have the ability to colonise and infect susceptible patients. Rhodotorula species are ubiquitous saprophytic yeasts that can be recovered from many environmental sour...

A cellulose-degrading defined mixed culture (designated SF356) consisting of five bacterial strains (Clostridium straminisolvens CSK1, Clostridium sp. strain FG4, Pseudoxanthomonas sp. strain M1-3, Brevibacillus sp. strain M1-5, and Bordetella sp. strain M1-6) exhibited both functional and structural stability; namely, no change in cellulose-degrading efficiency was observed, and all members st...

Twelve strains placed in the genera Flavobacterium, Pseudomonas, and Aureobacterium, including soil isolates, were characterized taxonomically. On the basis of morphological, physiological, and chemotaxonomic data, as well as DNA-DNA hybridization data, we propose that 11 of these strains should be classified in the genus Aureobacterium as new combinations or new species, as follows: Aureobacte...

The present study was carried out in order to examine and characterize the bidirectional hydrogenase in the cyanobacterium Nostoc sp. strain PCC 73102. Southern hybridizations with the probes Av1 and Av3 (hoxY and hoxH, bidirectional hydrogenase small and large subunits, respectively) revealed the occurrence of corresponding sequences in Anabaena variabilis (control), Anabaena sp. strain PCC 71...

Twenty mollicute strains isolated primarily from insect hosts were characterized and arranged into eight new species in the genus Mesoplasma. Morphological examination of the organisms by electron and dark-field microscopic techniques revealed that the cells of each strain were small, nonhelical, nonmotile, pleomorphic, and coccoid and that each cell was surrounded by a single cytoplasmic membr...

Reference strains, including two mis-named organisms, 'Chromobacterium chocolatum' and Flavobacterium marinotypicum, isolates from soil and clinical specimens, all previously recognized as Aureobacterium or Microbacterium, were characterized taxonomically. On the basis of morphological, physiological and chemotaxonomic characteristics, as well as DNA-DNA hybridization data, six new species and ...

A deep-sea isolate of the psychrotolerant yeast Cryptococcus sp. (NIOCC#PY13) obtained from polymetallic nodule-bearing sediments of the Central Indian Basin was examined for its capacity to grow in the presence of various concentrations of the heavy metal salts i.e., ZnSO4 , CuSO4 , Pb(CH3 COO)2 and CdCl2 . It demonstrated considerable growth in the presence of 100 mg/l concentrations of the a...
