Publikováno v: Advances in Microbiology. 11:616-629

Bioethanol is thought to be a renewable source of energy, because the biomasses used to make ethanol, such as sugar cane and its residual substance, molasses, are resources that can be continuously produced. But the practical use of ethanol to replac

Publikováno v: Advances in Microbiology. 10:318-330

We are confronting a new threat in the prevalence of antibiotic-resistant bacteria followed by epidemic spread in aquatic environments in metropolitan areas because damage from river floods is increasing remarkably in Japan due to global extreme weat

Comparison of Benzo［a］pyrene-Degrading Activities between Olleya sp. ITB9 Isolated from Tokyo Bay and Other Type Strains of the Genus Olleya

Autor: Naoto, Urano, Aya, Matsushima, Shione, Yamamoto, Rintaro, Endo, Masami, Ishida, Masahiko, Okai, Toshinori, Takei, Masachika, Takashio

Publikováno v: Biocontrol science. 26(4)

Benzo［a］pyrene (BaP) is one of the strongest carcinogenic compounds among polycyclicaromatic hydrocarbons (PAHs) .We previously identified the ITB9 strain of Olleya species, which shows BaP-degrading activity; our report was the first about BaP d

Comamonas sp. 3ah48 is a dibenz[ a,h ]anthracene‐degrading bacterium that is tolerant to heavy metals

Autor: S. Yamamoto, M. Takashio, Naoto Urano, Masami Ishida, Y. Ohki, Masahiko Okai

Publikováno v: Letters in Applied Microbiology. 68:589-596

Industrialization often causes polycyclic aromatic hydrocarbon (PAH) and heavy metal contamination of soil and water. In this study, we isolated a bacterium from bottom mud water around a park of Kawasaki Port, Japan, that degrades the 5-ring PAH dib

Bioethanol Production from Molasses by Yeasts with Stress-Tolerance Isolated from Aquatic Environments in Japan

Autor: Masachika Takashio, Naoto Urano, Masami Ishida, Masahiko Okai, Yuka Naito

Publikováno v: Advances in Microbiology. :1000-1011

Bioethanol is a safe and renewable source of energy that continues to be a research focus, since fossil fuels have been linked to global warming and nuclear energy sources are affected by the increased safety concerns following the 2011 nuclear power

Molecular Phylogeny and Phenotypic Characterization of Yeasts with a Broad Range of pH Tolerance Isolated from Natural Aquatic Environments

Autor: Naoto Urano, Masami Ishida, Yuka Naito, Masahiko Okai, Masachika Takashio, Ayaka Shirao

Publikováno v: Advances in Microbiology. :56-73

In this study, yeasts with broad range of pH tolerance were isolated and characterized from natural aquatic environments in Japan. Only a few basic and application studies of alkali-tolerant yeasts have been reported, despite the unmet industrial nee

Effect of Acid Species on Cryptococcus sp. T1 and Construction of Its Bioreactor System for Continuous Neutralization of Acidic Media

Autor: Masami Ishida, Yuko Yuko Kajiwara, Masahiko Okai, Sayaka Toyama, Shintaro Nagaoka, Naoto Urano

Publikováno v: Advances in Microbiology. :74-86

Generally, the tolerance of yeasts to acid is stronger than that of bacteria. In addition, some of the yeasts are able to neutralize acidic media, which is called acid-neutralizing yeast. An acid-neutralizing yeast, Cryptococcus sp. strain T1, was pr
