The methods are suitable for harvesting NVPO from aqueous culture with total dissovled solids (TDS) of at least 1500 mg/L. Methods are also provided to harvest a NVPO using flocculation with or without a Dissolved Air Flotation (DAF) process. Methods are further provided to flocculate and harvest a NVPO directly in a pond. The present application further provides NVPO-containing intermediates, compositions, or products produced by the methods provided herein.
