2 A layer present between cell wall and membrane of bacteria
3 Cell wall of bacteria
4 Bacterial cell glyco-engineered to possess Nglycosylated proteins
Explanation:
Glycocalyx is a carbohydrate protein layer that is covered on many of the eukaryotic and prokaryotic cells. - It is a sticky gelatinous material that is present outside the cell wall of bacteria, to form an additional surface layer. It is gel-like meshwork that surrounds the cell, constituting a physical barrier for any object to enter the cell. When this layer is firmly attached to the surface of the cell, it is called a capsule.

What is true for cyano bacteria :-
1 Oxygenic with nitrogenase
2 Oxygenic without nitrogenase
3 Non oxygenic with nitrogenase
4 Non oxygenic without nitrogenase
Explanation:
Cyanobacteria, also known as blue green algae (BGA) are photosynthetic prokaryotes. According to Bergey's classification, they are oxygenic photoautotroph. Certain filamentous Cyanobacteria can also act as nitrogen fixers. Nitrogen fixation in cyanobacteria is carried out by nitrogen -fixing cells called heterocysts, which have a thick cell wall and presence of oxygen scavenging proteins.

What is true for plasmid : -
1 Plasmids are widely used in gene transfer
2 These are found in virus
3 Plasmid contain gene for vital activities
4 These are main part of chromosome
Explanation:
Plasmids have the ability to replicate independently which makes it an excellent cloning vector in the recombinant DNA technology for manipulating and transferring genes. They are widely used in genetic engineering for gene transfer.

An organism used as a Biofertilizer for raising soyabean crop is :
1 Nostoc
2 Azotobacter
3 Azospirillum
4 Rhizobium
Explanation:
Rhizobium is a bacteria that live inside the root nodules of the leguminous plant. Rhizobium is used as a biofertilizer for raising crop (soyabeans and pea). Rhizobium japonium forms a symbiotic association with the plant.

Which of the following is mainly produced by the activity of anaerobic bacteria on sewage?
1 Marsh gas
2 Laughing gas
3 Propane
4 Mustard gas
Explanation:
The activity of anaerobic bacteria on sewage produces biogas, commonly called gobar gas or marsh gas. Marsh gas produced by physical treatment or primary treatment organic matter (Cow dunk, plant leaves etc) decomposed by activity of anaerobic bacteria in sewage treatment processes produced a rich amount of marsh gas
