✦ Synopsis

The problem of dilute solvent concentration in butanolacetone fermentations can be solved by using reverse osmosis to dewater the fermentation liquor. Polyamide membranes have a potential application in a butanolacetone fermentation and exhibited rejection rates as high a s 98%. Optimum rejection of butanol in the fermentation liquor occurred at recoveries of 20-45%. Flux ranged from 0.05 to 0.6 L m-* min-'. * Names of manufacturers or trade names are provided for information only and do not constitute an endorsement by any agency or department of Texas A&M University or any agency or department of the government of the United States.

## Abstract The order of ion separation by the NS‐100 membrane differed slightly from that of the cellulose acetate membrane. The separation of an ion by the NS‐100 membrane increased with increase in the valence of the ion, but decreased with the increase in the ionic radius. The sole criterion de

## Abstract **BACKGROUND:** Attempts were made to determine the lactic acid production efficiency of novel isolate, __Enterococcus faecalis__ RKY1 using four different starches (corn, tapioca, potato, and wheat starch) with different concentrations (50, 75, 100, and 125 g L^−1^) and corn steep liqu
