    Abstract Carbon dioxide utilisation (CDU) technologies hold promise for helping to limit atmospheric releases of CO2 while generating saleable products. However, while there is growing investment in the research and development required to bring CDU to the market, to date there has been very little systematic research into public perceptions of the technology. The current research reports upon the findings of a series of six qualitative focus groups (and an associated questionnaire) held with members of the UK public in order to discuss the perceived benefits and risks of CDU technology. The findings reveal that public awareness of CDU is currently very low and that there is a desire to learn more about the technology. While our participants did, on average, appear to develop an overall positive attitude towards CDU, this attitude was tentative and was associated with a number of caveats. The implications for the findings in terms of the development of communication and broader strategies of public engagements are outlined.

    Abstract A screening procedure using the ratio of total N to total S (N/S) was developed for indexing methionine and cystine concentrations in seed of soybeans—Glycine max (L.) Merrill—and its putative ancestor G. soja Sieb. and Zucc. Percent N was determined by the standard micro-Kjeldahl procedure. Total S was analyzed by reducing SO₄-S (from nitric acid-perchloric acid digestion) to H₂S and then percent S was determined by titration with HgCl₂ using dithizone as an indicator. The N/S values found in the soybean genetic type collection ranged from 24.5 to 15.4 with the mean being 18.3. The N/S values found in plant introductions of G. max that were formerly known as G. gracilis Skvortz. ranged from 20.1 to 16.3 with the mean being 18.4. The N/S values found in plant introductions of G. soja ranged from 21.5 to 12.5 with the mean being 17.5. Results from a 2-year investigation on the effect of growing seasons on the N/S ratios in seed revealed that the N/S ratios were quite stable from year to year in G. max and somewhat less stable in G. gracilis and G. soja. Attempts to identify the source of variation indicated that the variation in N/S values in seed of G. gracilis and G. soja largely were due to N content. The reasonably high correlation coefficients between mg of methionine and cystine with percent S (r = 0.846) and g methionine and cystine/16 g N with N/S ratios (r = 0.787) suggest that rapid screening for N and S Glycine germplasm would be helpful in directing investigators to lines that warranted further study.
