Figure 1. Recovery of MS2 in D–E-enriched PBST for different types of materials, surface contact times (CTs), and analytical hold times (HTs).

Figure 1.

Data are reported as the arithmetic mean of recovered PFU ± 1 standard deviation; spiked concentration of MS2 was at 1 × 108 PFU level. Testing was performed on 18-mm coupons and four types of materials: non-grimed concrete (A), grimed concrete (B), non-grimed plywood (C), and grimed plywood (D). Extraction buffers: D–E broth-enriched PBST (1:10, v/v); MS2 surface contact time from spiking to extraction (CT); analytical holding time from extraction to plating (HT); and not analyzed (NA). The next-day plating (HT = 24 h) was not performed due to the low recovery observed for the same-day HT (<8 h) analyses.
