Wastewater Generation

The dairy industry continues to grow with the growing population. It is considered the most polluting industry in terms of water consumption and wastewater generation. It generates about 6 to 10 litres of organically loaded effluent per litre of milk processed depending upon the products manufactured. Indian Standard (IS) 8682:1977 gives the guidelines for the treatment and disposal of dairy wastewater to protect the environment. The dairy effluent generally has dilutions of milk products generated from washing of floor, storage means such as cans, tanks, milk spillage, liquid effluent of cheese, paneer and yoghurt production called whey. It has high Chemical Oxygen Demand (COD) due to presence of organic contents because of fats, proteins and carbohydrates. To reduce the effect of the dairy wastewater on the environment, it is necessary to adapt some advanced techniques. Generally, all the food industries including the dairy industry look upto the membrane processes to recycle and reuse the wastewater. Membrane filtration is not only used for reclamation and reuse but also for fractionation of whey, recovery from cleaning solutions and various other processes. Thus, this paper is a mini review which gives various details about the dairy industry wastewater.

The present study focused on the various advanced oxidation processes; Ozone, UV radiation, O<sub>3</sub>/H<sub>2</sub>O<sub>2</sub>, O<sub>3</sub>/UV, UV/H<sub>2</sub>O<sub>2</sub> and O<sub>3</sub>/UV/H<sub>2</sub>O<sub>2</sub> for treatability of dairy industry wastewater. With this aim, the trials were carried out in cylindrical reactor fortified with UV radiation and Ozone injection. Efficiency of the treatment process was evaluated considering Chemical Oxygen Demand (COD), lactose reduction and process parameters were determined to be reaction time, pH, circulation rate, and H<sub>2</sub>O<sub>2</sub> dosage. 32.5%, 35.2% , 25%, 83% COD and 40.6%, 43.6%, 38.2%, 80% lactose reduction efficiency were obtained under the operating conditions for O<sub>3</sub>/H<sub>2</sub>O<sub>2</sub>, O<sub>3</sub>/UV, UV/H<sub>2</sub>O<sub>2</sub> and O<sub>3</sub>/UV/H<sub>2</sub>O<sub>2</sub> processes, respectively. As per this outcome, UV/H<sub>2</sub>O<sub>2</sub>/O<sub>3</sub> process gave more than 65% of COD and 52.36% of lactose reduction efficiency than other hybrid processes. Optimum conditions for UV/H<sub>2</sub>O<sub>2</sub>/O<sub>3</sub> process (pH = 5, time = 180 mins, circulation rate = 50 mL/h and H<sub>2</sub>O<sub>2</sub> dosage of 0.5 mL) resulted in 88% of COD and 93.4% lactose reduction.

Abstract Bacteriophages and their endolysins, enzymes that degrade the cell walls of bacteria, are emerging as alternative tools to detect and inhibit growth of pathogen bacteria. Listeria monocytogenes is a foodborne pathogen that causes listeriosis, a serious invasive disease that affects both humans and a wide range of animals. Listeria spp. are ubiquitous in the dairy farm environment and could be present in dairy-processing plants and wastewater. All Listeria-specific bacteriophages found to date are members of the Caudovirales, of the Siphoviridae or Myoviridae families. Myophages infecting Listeria have been recently classified by the ICTV in the Spounavirinae subfamily, as well as in the P100 virus genus. The aim of this work was to isolate Listeria spp. bacteriophages and their endolysin codifying genes from wastewater of a dairy industry. Wastewater with and without treatment was sampled during the course of a year, and isolation of bacteriophages was performed after an enrichment step using as hosts L. innocua, L. ivanovii, and L. monocytogenes serotypes 1/2a, 1/2b, and 4b. Bacteriophages infecting L. innocua and L. ivanovii were isolated (n = 24) from 3 out of 12 samples. Bacteriophages were purified, and the host range was determined using spot test and EOP against five collection strains and several field isolates of Listeria spp. Two bacteriophages of narrow and broad host range, vB_Lino_VEfB7, and vB_Liva_VAfA18, were selected for further characterization. High titer stocks of bacteriophages were purified by centrifugation with ammonium acetate, and morphological information on the purified bacteriophages was obtained by negative staining and transmission electronic microscopy. Their morphology, size, and contractile tails indicated that these bacteriophages belonged to the Myoviridae family. Bacteriophage genomes were extracted using phenol-chloroform, followed by ethanol precipitation, and tested by digestion with RNAsa A and DNAse I. RFLP was performed, digesting genomes with restriction enzymes HindIII and NcoI. Consistent with the morphological findings, bacteriophages contained dsDNA genomes but showed different RFLP patterns. A PCR designed to amplify conserved domains of endolysins—PGRP and CwlA—was applied to characterize this gene. Another PCR was designed to amplify the complete endolysin gene, and the complete sequence of this gene was obtained and analyzed. Substitution model selection and a maximum likelihood phylogenetic tree of the endolysin gene was carried out using IQ-Tree software. The sequences of the endolysin gene indicated that the codified enzyme is an N-acetyl-muramoyl-L-alanine amidase, related to A511 and P100 species of the recently described P100virus genus. Further evolutionary analyses are needed to evaluate their belonging to this species or their taxonomy within this genus.
