Effects of variability on protein yields for each individual interaction within both treatment groups are also compared in Fig. 2. For sun dried samples, ultrasonicated LEA had significantly higher (P < 0.001) protein yield while autoclaved LEA showed significantly lower (P = 0.026) protein yield than whole cell algae. No significant differences were observed between yields of microwave and NaCl assisted LEA and yield of whole cell algae. Ultrasonication assisted LEA also showed significantly higher (P < 0.001) protein yields than whole cell algae for oven dried samples. Similarly autoclaving significantly lowered (P = 0.002) protein yield than whole cell algae. For freeze dried samples, whole cell algae showed significantly higher protein yields than LEAs assisted with autoclave (P = 0.01), microwave (P < 0.001), or NaCl (P < 0.001); while ultrasonicated LEA had comparable (P = 0.533) yields to whole cell algae. The effects of different drying methods with each cell disruption procedure is also compared in Fig. 2. Sun dried LEA as well as whole cell algae samples had significantly lower (P < 0.001) protein yield than oven dried samples for all cell disruption methods. Similar yields of sun dried samples were lower (P < 0.001) than freeze dried samples for whole cell algae and autoclaved LEA only. Oven drying also produced higher yields than freeze drying for microwave, ultrasonication, and NaCl assisted LEA.
