slaughterhouse wastewater is mainly containing blood, stomach waste and some portion of fats. it is also a carbon and nitrogen source can we use them to produce PHA by bacteria.
I would assume yes, if the 'nutrient' (e.g. protein) concentration is high enough, witch I doubt. You will have an issue with natural bacteria in the waste water (especially of you have "stomach waste" rich in bacteria, as this natural bacteria are likely to compete with your bacteria
Running google scholar I found a paper by @Ciro Fernando Bustillo-Lecompte and @Mehrab Mehrvar Article Slaughterhouse wastewater characteristics, treatment, and ma...
They give parameters for slaughterhouse wastewater, among them mean BOD5 = 1209 mg/L and max 4635 mg/L. You could grow bacteria on this.
Another issue to consider is C/N ratio, in the same paper they report rather high total nitrogen (mean 487, max 841). If all the nitrogen is available to the bacteria you will get ~3:1 C:N ratio, I will assume too be too high for PHA accumilation. See https://www.researchgate.net/publication/282929241_Effect_of_CN_ratio_on_polyhydroxyalkanoates_PHA_accumulation_by_Cupriavidus_necator_and_its_implication_on_the_use_of_rice_straw_hydrolysates
Still another question will be the presence of antibiotics and pathogens.
Bottom line - if you have access to such water, give it a try!
Yes, it is possible to use Slaughterhouse wastewater as a substrate to produce polyhydroxyalkanoates. However, the wastewater must first be treated to remove contaminants and pollutants before it can be used as a substrate. Additionally, the composition of the wastewater must be suitable for the particular strain of bacteria used to produce the polyhydroxyalkanoates.
