Remediation of Food Production and Processing Effluents and Waste Products
The subject invention provides methods for improving the treatment of effluents and waste matter produced during food processing and production. In particular, the subject invention provides methods for remediating fats, oils and greases (FOG), suspended solids, proteins, and other organic matter that are discharged from plants that process, for example, meats, poultry, seafood, dairy and plant-based oils. The methods of the subject invention utilize a customized microbial cocktail comprising facultative anaerobes, in combination with one or more microbial growth by-products, e.g., enzymes and/or biosurfactants, to digest and/or liquefy food processing waste matter.
1 . A method for improving the treatment of food processing waste present in wastewater, the method comprising:
taking a sample from the wastewater, wherein the sample comprises one or more types of food processing waste matter;
analyzing the sample to determine the identity of the one or more types of waste matter; and
introducing a customized microbial cocktail comprising one or more beneficial microbial species into the wastewater to increase the throughput of treating the waste matter.
2 . The method of claim 1 , wherein the wastewater is present in an anaerobic digestor, a lagoon, or a body of water into which food processing waste matter has been introduced.
3 . The method of claim 1 , wherein the food processing waste matter comprises palm oil milling effluent (POME).
4 . The method of claim 1 , wherein the food processing waste matter comprises acid-whey.
5 . The method of claim 1 , wherein the food processing waste matter comprises fats, oils and greases (FOG).
6 . The method of claim 1 , wherein the microbial cocktail comprises one or more facultative anaerobic bacteria capable of producing enzymes and/or other growth by-products for digesting, purifying, decontaminating, and/or removing the food processing waste matter from the wastewater.
7 . The method of claim 6 , wherein the microbial cocktail comprises bacteria selected from Bacillus subtilis, B. licheniformis, B. firmus, B. laterosporus, B. megaterium , and B. amyloliquefaciens.
8 . The method of claim 6 , wherein the microbial cocktail comprises bacteria selected from Pseudomonas aeruginosa, P. chlororaphis, P. mallei, P. pseudomallei, P. fluorescens, P. alcaligenes, P. mendocina, and P. stutzeri.
9 . The method of claim 6 , wherein the microbial cocktail comprises one or more nitrate-reducing bacteria (NRB), and wherein the method results in denitrification of wastewater, and/or removal of nitrates and/or ammonium from the wastewater.
10 . The method of claim 1 , wherein the sample further comprises a microbial community comprising one or more microbial species.
11 . The method of claim 10 , which further comprises analyzing the microbial community to identify the microbial species present within the microbial community and the population percentage of the species;
determining which microbial species are beneficial, commensal and/or detrimental to treatment of the food processing waste, and further determining whether or not the commensal and/or detrimental species comprise at least 25% of the microbial community, wherein a percentage of commensal and/or detrimental species of 25% or greater means the microbial community is in dysbiosis; and
if the microbial community is in dysbiosis, introducing the microbial cocktail into the wastewater to improve the balance of the microbial community and increase the throughput of wastewater treatment.
12 . (canceled)
13 . The method of claim 1 , further comprising applying one or more microbial growth by-products to the wastewater to further enhance the treatment of the wastewater and/or the activity of the microbial cocktail.
14 . The method of claim 13 , wherein the microbial growth by-products are biosurfactants selected from glycolipids, lipopeptides, cellobiose lipids, flavolipids, phospholipids, lipoproteins, lipopolysaccharide-protein complexes, and polysaccharide-protein-fatty acid complexes.
15 . (canceled)
16 . The method of claim 14 , wherein the biosurfactants are sophorolipids.
17 . The method of claim 1 , wherein nitrous oxide and/or methane emissions from the aerobic digester, lagoon and/or body of water are reduced.
18 . (canceled)
19 . The method of claim 1 , wherein the number of sulfate-reducing bacteria (SRB) in wastewater is reduced.
20 - 31 . (canceled)
