Genetic modification of rumen bacteria by using rDNA technology may improve the rate or extent of lignocellulolysis in the animal. The task of developing effective rDNA technology in rumen bacteria, particularly for improving lignocellulose digestion is complex. After the rate limiting steps have been defined, it is necessary to identify and clone suitable heterologous genes for insertion into a rumen [...]
In this article we will discuss about the biodeterioration of various materials. 1. Biodeterioration of Stored Plant Food Material: The stored (unprocessed) plant material (fruits, seeds, etc.) are usually decayed due to post harvest attack of bacteria and fungi. This kind of spoilage is called biodeterioration. However, loss of plant materials before harvest is covered in plant pathology. The microbes [...]
In this article we will discuss about the evolutionary relationships of bacteria. The early investigators considered bacteria as animalcules and place them with the Protozoa. This viewpoint was held up to the middle of the last (nineteenth) century. Some assigned them a position of the border line between plants and animals. They place this group of structurally simple organisms, which [...]
