Science

As you have completed your Masters in Organic Chemistry, I will suggest you to go with CSIR NET Chemical Science subject. The basic objective is to determine eligibility for college & university level lectureship and for award of Junior Research Fellowship (JRF) for Indian nationals in order to ensure minimum standards for the entrants in the teaching profession and research. On behalf of UGC, the Central Board of Secondary Education holds National Eligibility Test NET for determining the eligibility of Indian nationals for the Eligibility for Assistant Professor only or Junior Research Fellowship & Eligibility for Assistant Professor Both in Indian universities and colleges.

Either Teaching or Research. It depends upon one's personal choice.
Teaching gives better monetary prospects! And kinda easier job if one has proper knowledge and hold on the subject.
While research in India is still in an infancy stage. For curious researchers its a go.

Microbiology Ph.D. recipients can becomeClinical Microbiologistand run a Clinical Microbiology Lab. They deal with identifying bacterial, viral, fungal and parasitic infections which helps to prevent epidemics and has a large influence on the clinical management of patients. Plays a central role in the detection of new infectious agents. They work closely with clinicians and healthcare professionals to determine the method of sampling, confirms the cause of infections in humans and animals and what antimicrobial agents may be effective for treatment. They also work to prevent and control of infectious human diseases and other health hazards caused by pathogenic microorganisms. Legal
As a lot of biotechnology uses microbes (and getting a Ph.D. in Microbiology generally makes you biology literate), there is a demand for people with these skills to go into fields likePatent lawandTechnology transfer. Government
While there is significant overlap with what academic microbiologists study as well as government-working microbiologists, those in the government often deal with questions of bioterrorism and research surrounding microbiology as relevant to the military and public health. Outside of the research context, many scientists choose to go into administrative roles, such as grant management. Industry
From pharmaceutical, biotechnological, dairy to brewing companies, microbiologists are often employed to do research, quality control, produce development as well as manage facilities.
