  1. Estimating the enzyme specificity and glucose concentration of sugar solutions

    Rishan Singh

    e405

    The function of the human body are controlled by enzymes and hormones. Similarly, in the laboratory, the enzyme, glucose oxidase, is used to hydrolyse glucose. In the human body, glucose and insulin control blood glucose levels, which are dependent on food intake. In this study, the enzyme specificity and glucose...

  7. Microbial communities and activities in caves

    Ramat Onyeneoyiza Raji, Oluwafemi Adebayo Oyewole, Omeiza Haruna Ibrahim, Yetunde Noimot Tijani, Mordecai Gana

    e411

    Caves are natural aperture and oligotrophic extreme environment for psychrophilic and psychrotolerant microorganisms. Microorganisms found in caves can be indigenous to the caves or introduced by humans, animals, water flow and wind action. Group of microorganisms found in caves are bacteria, fungi, protozoa,...

  9. Applications of endophytic-fungal-isolates from velamen root of wild orchids in floriculture

    Azhanthanilkunnathil S. Deepthi, Joseph G. Ray

    e413

    The velamen roots are quite extensively growing and profusely branched organ of adaptation in epiphytic orchids. The endophytic-fungi in such roots are believed to have growthpromoting influence, especially on the roots itself. However, an application of the same in the cultivation of the ornamental orchids is...
