Master Plant Biotechnologist interested in imparting knowledge on biology and medicine.


Aishwarya G Iyer

This course will make you understand microscopic organisms such as Bacteria , viruses , archaea, fungi and protozoa. It includes fundamental research on the biochemistry, physiology, cell biology, ecology, evolution and clinical aspects of microorganisms, including the host response to these agents.

Microbiology for GATE

In this video , I have given an overview of the topics I will be dealing in this course Microbiology.
The topics in this course are :-
1) Viruses: Structure and classification
2) Microbial classification and diversity
3) Methods in microbiology
4) Microbial growth and nutrition
5) Aerobic and anaerobic nutrition
6) Nitrogen fixation
7) Microbial diseases
8) Host-pathogen interaction
PS: Sorry about the background disruption in the last, that was unexpected.

Microbiology (overview)

This video explains about the great contributions and theories proposed by the scientists in the development of microbiology . History of microbiology is classified into different eras - Discovery era , transition era , golden era and modern era. I have talked about all these eras in detail.

History of Microbiology

This video explains about the classification of microbes in detail. It includes classification based on morphology , nutrition , biochemicals , staining reactions & Serology/antigens.
PS: Sorry for the background noise, Ignore the background disruption.

Classification of Microbes

This video gives an introduction of virus , modes of transmission through which the virus is spread and it also gives an information on the discovery of virus and the contribution of the scientists in the development of virology.

Virus: Structure and function

This lesson describes about the three main theories speculated on the origins of viruses - Regressive theory , cellular origin theory and coevolution theory. I have also talked about the problems with these theories . I have explained about the characteristics of a virus , made a comparison of a virus with a cell for a better understanding ,discussed about the size of the virus and the techniques used to stain the structure of a virus , tools for studying structure  & discussed about the structural symmetries of different viruses - Icosohedral , enveloped Icosohedral , helical , enveloped helical.

Virus: Structure and Classification (Part 2)

This video describes about the viral reproduction , 3 types of system to classify viruses- Baltimore classification , classical system classification and genetic classification and a basic information on the applications of virus.

Virus : Structure and Classification (Part 3)

I have briefly talked about the methods used in microbiology ( laboratory techniques ) - 1) Inoculation of Liquid and Solid ( Slant ) culture Tubes , 2) Serial dilutions & 3) A basic information on preparation of LB broth ( I have not mentioned the quantity or composition of the extracts/chemicals used in LB broth preparation , I will be talking about the composition of biochemicals used in LB broth preparation in my upcoming lessons )

Methods in Microbiology

This video describes about the the the nutrition requirements - Macro and micro nutrients , sources of carbon, energy and electron , nutritional type of organism , growth factors and the functions of vitamins in microbes . I have also talked about the uptake of nutrients by microbial cell.
PS : Ignore the noise disruption at the start ( mic problem )

Microbial Growth and Nutrition (Part 1)

This video explains about different stages of microbial growth in detail along with the growth curve and it also gives information on generation time.

Microbial Growth and Nutrition (Part 2)

In this video , I have talked about Host-pathogen interaction in detail , I have discussed about portal of entry , portal of exit , modes of transmission , reservoir and susceptible host.

Host Pathogen Interaction

This video briefly talks about nitrogen fixation in plants.
