Summary Introduction

To explain:

The process by which glucose from cellulose in plants can be extracted for use in bio-fuel production.

Concept Introduction:

Fermentation is a process of breakdown of complex carbohydrates present in food into simpler compounds by microorganisms. It takes place under anaerobic conditions under proper conditions of temperature and pH. There are enzymes present in bacteria which degrade carbohydrates into smaller compounds inside the cell.

Explanation of Solution

Lignin is an organic polymer of aromatic coumaryl alcohol and is present in plant vascular tissues. It is connected to glucose molecules. Fermentation causes the degradation of this polymer to release glucose molecules used as essential metabolites in fermentation pathway. The strain of bacteria which break down lignin is Rhodococcus jostii and cellulase enzyme digests cellulose for the production of biofuels from these plant extracts.

Conclusion

Biofuels can be produced from plants by the process of fermentation from microorganisms like bacteria and fungi.

Summary Introduction

To explain:

The microorganisms used in the process of fermentation to produce bio-fuels.

Concept Introduction:

Bio-fuels are prepared from waste extracts of plants. It includes the processing of wood-chips, pellets and organic materials to produce bio-ethanol in the laboratory. It covers about 10% of the world energy. Vegetable oil, animal fat and alcohol are combined to produce bio-diesel. The process of transesterification produces bio-diesel.

Expert Solution

Explanation of Solution

Micro-organisms which produce bio-diesel are as follows Rhodococcus jostii and various species of algae like Phaeodactylum tricornutum. The other species of algae include Kirchneriella lunaris,Lyngbya kuetzingii,Selenastrum capricornutum, Chlorella vulgaris, Scenedesmus obliqnus, and Isochrysis sphacrica.

Conclusion

There are various species of algae which produce bio-diesel.

The diagram below illustrates a quorum sensing pathway from Staphylococcus aureus. Please answer the following questions. 1. Autoinduction is part of the quorum sensing system. Which promoter (P2 or P3) is critical for autoinduction? 2)This staphylococcus aureus grows on human wounds, causing severe infections. You would like to start a clinical trial to treat these wound infections. Please describe: a) What molecule do you recommend for the trial. Why? b) Your trial requires that Staphylococcus aureus be isolated from the wound and submitted to genome sequencing before admittance. Why? What are you testing for?  3) If a mutation arises where the Promoter P3 is constitutively active, how would that influence sensitivity to AIP? Please explain your rationale. 4) This pathway is sensitive to bacterial cell density. Describe two separate mutation that would render the pathway active independent of cell density. Briefly explain your rationale. Mutation 1 Mutation 2
