Analysis of the hupSL operon of the nonheterocystous cyanobacterium Lyngbya majuscula CCAP 1446/4: regulation of transcription and expression under a light-dark regimen.

abstract：:DNA probes that are specific for each of five predominant species of human colonic Bacteroides (B. thetaiotaomicron, B. uniformis, B. distasonis, "Bacteroides group 3452-A", and B. ovatus) were used to detect and enumerate these species in fecal samples from two adult volunteers. These five species are capable of ferm...
