E. coli belongs to the genus Escherichia

Taxonomically, <em>Escherichia coli </em>is categorized as belonging to the phylum Proteobacteria, class Gammaproteobacteria, family Enterobacteriaceae, order Enterobacteriales, and genus Escherichia (named after its discoverer, Theodor Escherich).

  • Escherichia coli (E. coli) are typically found in warm-blooded organisms' lower intestines. The majority of E. coli strains are not harmful, but some can seriously poison food.

  • A  Shiga toxin-producing E. coli (STEC) is capable of causing severe foodborne illness.
  • Raw or undercooked ground meat products, raw milk, and fecal contamination of vegetables are the most common causes of STEC outbreaks.
  • The illness is usually self-limiting, but it can progress to a potentially fatal condition like haemolytic uraemic syndrome (HUS), especially in young children and the elderly.

To efficiently provide the ideal amount of nitrogen fertilizer, some farmers make use of a "chlorophyll meter" that measures the
NikAS [45]

Answer:

Chlorophyll is a green pigment found in chloroplast in plants. It absorbs sunlight during the process of photosynthesis. It is a chelate molecule. In a chelate molecule a central metal ion forms bonds with a large organic molecule made of carbon, hydrogen and other elements like nitrogen or oxygen.

In chlorophyll, magnesium is the central metal ion and it is bonded to a large organic molecule called as porphyrin. Porphyrin constitutes four nitrogen atoms to which the central magnesium is bonded in square planar arrangement. Since chlorophyll is responsible for the green color of the leaves, more the green color more the chlorophyll content and more is the nitrogen content. Hence, chlorophyll meter measures this green light and finds out if the plant needs more or less nitrogen.
