Microbiologist
Guindy, Chennai, Tamil Nadu
₹15,000 - ₹30,405 a month
Position Summary
The Microbiologist will work in an agriculture-focused laboratory to analyze soil, water, compost, fertilizers, biofertilizers, crop samples, and microbial cultures. The role involves microbial testing, quality control, culture maintenance, and supporting R&D activities related to plant growth, soil health, and agricultural inputs.
Key Responsibilities
1. Microbial Analysis Perform microbial enumeration (total plate count, fungal count, beneficial bacteria count). Isolate and identify agriculturally important microbes (e.g., Azotobacter, Azospirillum, PSB, Trichoderma, Rhizobium). Conduct contamination checks for biofertilizers, biopesticides, and fermentation samples. Examine soil microbes related to nutrient cycling (N, P, K).
2. Soil & Water Testing (Microbiology Side) Assess microbial biomass in soil. Evaluate water samples for microbial contamination affecting irrigation. Support organic farming evaluations (microbial load, pathogens, compost maturity).
3. Quality Control (QC) & Compliance Maintain sterility and perform routine QC checks on lab media and reagents. Follow BIS, FCO, ISO, or NABL standards depending on lab requirements. Ensure all test results meet regulatory and quality guidelines.
4. Culture Preparation & Maintenance Prepare selective/differential media for agriculture-related microbes. Maintain microbial stock cultures and keep them contamination-free. Support the production-quality checks for biofertilizers and biopesticides.
5. Data Recording & Reporting Record observations, colony counts, and test results accurately. Prepare microbial analysis reports for farmers, agribusiness clients, or internal R&D. Enter results into LIMS or lab record books.
6. R&D Support (if part of an R&D lab) Assist in developing improved microbial formulations (liquid/solid biofertilizers). Participate in field trials for microbial products. Conduct stability studies and performance evaluations.
Required Skills Knowledge of agricultural and soil microbiology. Familiarity with aseptic techniques and contamination control. Experience with microbial plating, serial dilution, incubation, colony counting. Understanding of beneficial agricultural microbes and their functions. Ability to prepare lab media and operate basic lab equipment (incubators, autoclaves, microscopes, colony counters, etc.).
Qualifications B.Sc / M.Sc in Microbiology, Biotechnology, or Agricultural Microbiology.
Experience: 0–3 years for junior roles; 3+ years for senior QC or research positions.
