There is considerable evidence for the existence of alternate pathways of glucose dissimilation in microbial systems (1). Several organisms belonging to the genus Xtreptomyces have been investigated by some workers (2, 3). Hockenhull et al. (4), Ganguly and Roy (5), and Wang et al. (6) have particularly studied Streptomyces griseus and showed that this organism utilizes both the glycolytic and ...

Studies initially concerned with the role of nutrient carbohydrates in the formation of capsular hyaluronic acid by various strains of Streptococcus pyogenes led to the finding that the end products of glucose and galactose dissimilation in these organisms differ quantitatively (Steele et al., 1954). This paper is a report of further investigations on the latter aspect of the carbohydrate metab...

The genome sequences of Methylomonas methanica (NCIMB 11130(T), R-45363, and R-45371), Methylomonas koyamae (R-45378, R-45383, and R-49807), Methylomonas lenta (R-45370), and Methylosinus sp. (R-45379) were obtained. These aerobic methanotrophs were isolated from terrestrial ecosystems, and their distinct phenotypes related to nitrogen assimilation and dissimilation were previously reported.

It has been long known that the four lexical tones in Mandarin are subject to contextual variation in connected speech. Most of the contextual tonal variation reported to date (not including phonological variation such as tone sandhi) is assimilatory in nature. In this study, however. both assimilation and dissimilation arc found in contextual tonal variation in Mandarin. Four Mandarin spealcer...
