Answer:
Biofuels like fuel from microalgae are very costly as compared to fossil fuels.
Explanation:
The cost of biofuels is too high as compared to that of fossil fuel. For instance,
the cost of 1 gallon of algal fuel is $32.81 per gallon while cost of diesel is $2.9 -3.2 per gallon.

Answer:
P. aeruginosa
Explanation:
<em>P. aeruginosa</em> is a gram-negative bacteria that belongs to the family Pseudomonadaceae.
From the given question the following points lead us to conclude that the colony that will be growing would be of P. aeruginosa :
1. Flat spreading colonies with a metallic sheen on SBA - <em>P. aeruginosa</em> is known to produce smooth colonies with flat edges.
2. Fluorescent green color in the media with clear colonies on cetrimide agar - <em>P. aeruginosa</em> is known to produce pyoverdin which is a fluorescent pigment under low iron conditions.
3. Medium clear colonies that have a "fruity or grape-like odor" on MacConkey Agar - <em>P. aeruginosa</em> has a sweet fruity odor which is its characteristic odor because of the production of trimethylamine.
Thus, from all these characteristics one can conclude that the organism in the culture is <em>P. aeruginosa. </em>
