“…These pollutants are lost during conventional process of treatment due to biological action. A clear understanding of the pollutant to be treated [16], the microbial metabolic pathway that breaks down/converts the pollutant into plant acceptable form [17][18][19] and the kind of microbes known to harbor these pathways [17][18][19][20] can lead to development of processes which would convert the pollutant into a value added product [21]. The dairy wastewater with enhanced phosphate and nitrate along with a high carbon:nitrogen ratio [22] could be used directly for sustaining bacterial growth.…”

The major bottleneck of dairy effluent treatment plant operation is the generation of 10 m3 of nutrient rich wastewater per m3 of milk processed resulting in an annual production of 7.93 tons of carbon dioxide equivalent (CO2 e) gas during treatment in a 7–8 step process. It is an expensive, non-ecofriendly, laborious process which is often not adoptable by the small segment installations. A carefully selected tailor-made bacterial consortium in biofilm reactor within 4 h of incubation in a single step operation under ambient condition could transform the total volume of wastewater into ammonia rich liquid biofertilizer generating 0.79 tons/year CO2 e gas. This biofertilizer replaces the use of fresh water and chemical fertilizer for agriculture, producing economic crops at par with chemical fertilizer. In certain cases, the production of crops is increased substantially over chemical fertilizer based growth. It reduced carbohydrate content of tuber crops. The generated liquid biofertilizer can overcome the shortage in fodder production without using chemical fertilizer and fresh water, hence solving one of the major concerns for sustaining the expansion of dairy industry, hence making dairy effluent treatment plant (ETP) operation an eco-friendly, self-sustainable operation.

Ammonia is required for various commercial applications while its production by standard process is immensely energy intense. Dairy industry on the other hand produces huge volume of effluent needing treatment before discharge. This study aims at developing an eco-friendly microbial approach for conversion of dairy industry effluent into ammonia under atmospheric pressure and 37°C temperature at laboratory scale. Thus the need for huge energy for ammonia production would be avoided. Moreover the dairy effluent would generate revenue while getting treated. This study is also an attempt to develop a bioinformatics approach for strain identification. Standard cultivation techniques and in-silico approach of analysis of draft genome was undertaken to decipher the identity of this industrially important strain. Aeromonas sp. MCC 2167 (isolated from active dairy sludge) was capable of treating un-amended dairy effluent with 6% inoculum while producing ammonia as by product at a 11 folds higher rate than the modified Habers Process. Though the strain showed maximum identity with Aeromonas hydrophila, there were certain differences in terms of substrate utilization. Majority of the contigs showed identity with Aeromonas hydrophila, however there was significant difference among the two strains in terms of intergenomic distance (genome to genome distance calculator from DSMZ), inversion and frame shift (dot plot analysis) as well as genome rearrangement (MAUVE analysis). As per the rapid annotation using subsystem technology analysis 53% of the contigs belong to the subsystem category while the remaining 47% do not match with existing sequences in the database. The above finding proposes bioinformatics validation of the wetlab based data pointing towards this industrially important strain to be a novel isolate of Aeromonas sp. This would lead to an energy efficient economically viable alternative for ammonia production while treating large bulk of effluent generated from dairy industry that needs to be treated before being discharged.
