Carbon monoxide-dependent chemolithotrophic growth of Clostridium thermoautotrophicum.

The acetogen Clostridium thermoautotrophicum was cultivated under CO-dependent chemolithotrophic conditions. CO-dependent growth profiles and energetics indicated that supplemental CO2 was fundamental to efficient growth at the expense of CO. Overall product stoichiometry approximated 6.5CO----CH3CO2H + 3.5CO2 + 0.6 cell C + 0.5 unrecovered C. Initial CO/CO2 ratios of 2 to 4 yielded optimal doubling times and cell yields. Maximal YCO values approximated 2.5 g of cell dry weight per mol of CO consumed; YH2 was considerably lower than YCO. Cross-transfer growth experiments and protein profiles indicated differential expression of genes between CO and methanol cultures.

Introducing preclinical students to primary care through a community preceptorship program.

In the 1980-81 academic year, the Morehouse School of Medicine implemented a preceptorship program designed to introduce preclinical students to primary care. The program is unique in that it is required for all first- and second-year students; it is continuous throughout the first two years of medical school; it exposes students to a variety of primary care specialties, settings, and practice modes; and it enables students to follow a family for one to two years. A preliminary evaluation of the program's first year indicates that it has had an impact on the students' attitudes, knowledge, and career plans. The objectives and operation of the program are described.
