“…Probiotics are defined as "living microorganisms that, when ingested in adequate amounts, confer a health benefit on the host" [5]. In the past few decades, probiotics have been actively studied for a variety of purposes, including pharmaceutical products, functional foods, wastewater treatment, livestock, and aquaculture [6][7][8][9][10]. Probiotics are being actively studied as an alternative to antibiotics due to their advantages of not generating residues or drug resistance in the body of animals [11].…”

In this study, two bacterial species, Salipiger thiooxidans and Exiguobacterium aestuarii, were extracted and screened from the Saemangeum Reservoir. This study examined these species’ suitability as a probiotic by confirming the effects of S. thiooxidans and E. aestuarii added to rearing water for L. vannamei. Three experimental groups were evaluated for 6 weeks: (1) a control group reared in natural (i.e., untreated) water (CON), (2) an experimental group in which S. thiooxidans was added to natural water (SMG-A), and (3) natural water inoculated with E. aestuarii (SMG-B). The SMG-B group inoculated with E. aestuarii showed significantly higher final body weight, weight gain, specific growth rates, and feed efficiency than the control group. The SMG-B group inoculated with E. aestuarii exhibited significantly higher levels of serum lysozyme, and ACP and ALP activity than the control and SMG-A groups. The SMG-A and SMG-B groups inoculated with probiotics showed significantly lower total ammonia nitrogen and nitrite than the control group. Our findings suggest that S. thiooxidans and E. aestuarii extracted from the Saemangeum Reservoir can improve the water quality of aquaculture water, and, in particular, E. aestuarii is a potential probiotic for L. vannamei.

Investigation of the efficiency of oil-containing wastewater sorption treatment with sawdust and probiotic agent addition

Purification of wastewater from petroleum products is an urgent problem for the Tyumen province as an oil and gas region. The use of natural materials is actively studied in the technologies of sorption cleaning which is the main method for oil pollution removal. One of these new technologies is the wastewater treatment method with the use of probiotic agents. The purpose of this research is to study the effect of probiotics on the degree of dissolved petroleum products extraction from aqueous solutions by phytosorbent (pine sawdust). The photometric method of liquid analysis was used as a standard method of research. As a result of the sorption process study, it was found that the concentration of petroleum products decreased faster and to a minimum value (by 48.68%) when filtering samples through a layer of sawdust soaked in a probiotic solution, which is 2 times more effective than pure sawdust. The sorbent used is environmentally friendly.

On the territory of the Tyumen region there are a number of enterprises that discharge wastewater without pretreatment into water bodies and disturb their ecological condition. For example, one of the dairy industry plants produces 500 m3/day of industrial wastewater, which cannot be discharged even into the domestic sewage system due to its pollution density and aggressiveness. Thus, it is necessary to study wastewater quality and the mode of its inflow for local waste treatment plants’ designing. This article presents the results of the wastewater composition study on such indicators as pH, biochemical oxygen demand, chemical oxygen demand, suspended solids, fats, nitrogen, phosphate and other types of pollution. According to the obtained data, the conclusions were drawn about the wastewater composition inconstancy, associated with peculiarities of dairy production technology. In addition, the drains are characterized by a high variation of pH medium, which decreases sharply when the whey or acid solutions are discharged into the sewage production system after equipment washing. Based on these results, a scheme for organization of a dairy plant water disposal system is proposed, including local pretreatment of wastewater before its dumping into domestic sewage network.
