Reduction of cyst infectivity due to UV exposure was quantified by applying most probable number techniques.
As long as massive oil spills are probable, special techniques and equipment will remain essential for facilitating spill cleanup in coastal regions.
Recovered survivors were enumerated by standard plate counting or the most probable number technique, as appropriate.
However, persistence estimated throughout the season using the most probable number technique and terminal restriction fragment length polymorphism (T-RFLP), was observed to be higher early in the season in inoculated plots and reduced with time.
The bacterial population was determined by the most probable number technique (MPN); positive growth was recognized by the formation of a thick, white pellicle, replication was threefold, and density was expressed as the log of cell number g−1 root fresh mass after growth on JNFb N-free semisolid medium (following Döbereiner et al. [35]).
The cyanophage experiments were done using similar methods, except that the cyanophage (myovirus S-SSM1, on Synechococcus) was grown in Pro99 medium (Moore et al., 2007) and assayed for titre using the most probable number technique (Sullivan et al., 2003).
First, repeated aerobic and anaerobic (with NO3−) liquid dilution series (according to the most probable number technique) were carried out separately with n-tetradecane or n-valerate (n-pentanoate).
On December 18, when a chocolate leftover from brand A tested positive, the investigations were tailored to German chocolates from company A. The BfR examined quantitatively four Salmonella positive chocolate leftovers and five chocolates from grocery stores using the most probable number technique [ 7].
In addition, cell counts of iron II), sulfur, and thiosulfate oxidizing, lithotrophic bacteria and chemoorganotrophic microorganisms were determined quantitatively by the most-probable-number technique or by agar-plating.
Tuyls et al. [10] and Kevenaar et al. [5] have used a similar equal-probable discretization technique but the bit allocation is limited to at most one bit per dimension.
Most Probable Number (MPN) techniques were applied in some investigations.
