Detection of Bacteriochlorophyll-containing Micro-organisms by Infrared Fluorescence Photomicrography

extremal region detection guided by maxima of gradient magnitude

a problem of computer vision applications is to detect regions of interest under dif- ferent imaging conditions. the state-of-the-art maximally stable extremal regions (mser) detects affine covariant regions by applying all possible thresholds on the input image, and through three main steps including: 1) making a component tree of extremal regions’ evolution (enumeration), 2) obtaining region ...

Utilization of S-adenosylmethionine by micro-organisms.

Shapiro, Stanley K. (Argonne National Laboratory, Argonne, Ill.). Utilization of S-adenosylmethionine by microorganisms. J. Bacteriol. 83:169-174. 1962.-Two types of mutants of Aerobacter aerogenes that utilize S-adenosylmethionine for growth are described. One type also responds to methionine, 5'methylthioadenosine, or a combination of homocysteine and S-methylmethionine. The second type of mu...

The utilization of pyridine by micro-organisms.

application of biofertilizers containing free-living nitrogen fixer micro organisms in agriculture

atmospheric nitrogen fixation as an exclusive phenomenon is accomplished by nitrogenase enzyme of prokaryotic microorganisms namely diazotrophs including bacteria, actinomycets and cyanobacteria. nitrogen fixation is accomplished as form of symbiotic, associative and free-living systems. in free-living systems nitrogen is fixed without the help of plants. azotobacter, the first diazotroph was d...
