hello every one
i am going to defense my phd research proposal and i want to study soil enzymatic activies but my supervisor suggest me you have to put some question that why you are studying enzymatic activities so what questions should i put in my proposal
thanks
Greetings dear colleague
I would like to tell you some things about the ecology of the soil and the importance of knowledge and study of the enzymatic reactions that occur in it. In this way you can answer any question of why the importance of these matter...
First, the soil is a key natural resource for life. This fact makes it highly studied from a multitude of points of view, framing these studies within what we know today as Soil Science. In this context, knowledge about soil enzymes is nowadays a line of research into the future to know its functionality and sustainability.
The fundamental importance of the activity of the enzymes of the soil lies in the fact that the functioning of this ecosystem can not be correctly understood without the participation of enzymatic processes, since the enzymes determine the pattern of a large part of the chemical transformations that take place in the soil.
The most studied soil enzymes are oxidoreductases (dehydrogenases, catalases and peroxidases) and hydrolases (especially phosphatases, proteases and urease). A part of the enzymes of the soil are extracellular, being released during metabolism and cell death. Others are intracellular, forming part of the microbial biomass. Finally, there are immobilized enzymes that are those that can maintain a constant and stable level of enzymatic activity in the soil, independent of the microbial proliferation and the usual forms of regulation of the synthesis and secretion of enzymes.
The enzymes of the soil offer information about their potential capacity to carry out specific reactions, which are important within the cycle of important nutrients such as C, N, P and S, and can provide key information on aspects related to the quality of the Soils. Certain enzymes show great sensitivity to undesirable processes such as soil contamination, degradation and even desertification, hence, although the physical and chemical component of the soil is important for it, it can be considered relatively stable.
However, considering the flexibility of the soil ecosystem (define it as a living and dynamic entity), we can think that any change can be detected in its beginning by its biological component (for example, by enzymes). Hence, soil enzymes (their existence or deficiency) can be considered as an "alert" to a possible environmental collapse, allowing us to react in time before irreversible damage to the aforementioned soil can occur.
I hope that my comment has been helpful and that you have these recommendations in mind.
good luck with your PhD defense
Thank you dear colleagues, it is a pleasure to be able to help you, if you consider that the answer may be useful please recommend it
