| genetic basis of nutritional requirements in lactobacillus casei. | in a study of the genetic basis of multiple nutritional requirements in lactobacillus casei, systematic attempts were made to isolate mutants that can grow in the absence of a specific nutrient required by the parental organism. such mutants have successfully been isolated with respect to seven of twelve amino acids (aspartic acid, leucine, isoleucine, lysine, methionine, serine, and threonine) and three of four vitamins (pantothenic acid, nicotinic acid, and pyridoxal) tested, after extensive s ... | 1974 | 4215789 |

| comparative biochemical and immunological study of malic enzyme from two species of lactic acid bacteria: evolutionary implications. | representatives of both streptococcus faecalis and lactobacillus casei produce isofunctional malic enzymes. all 10 strains of s. faecalis tested could be induced to synthesize malic enzyme and readily adapted to growth on malate. although 17 of 21 l. casei strains could be induced to produce malic enzyme, only 9 of 14 strains tested grew at the expense of malate. a comparison of catalytic and regulatory properties suggested that the malic enzymes from s. faecalis and l. casei were very similar. ... | 1971 | 4323962 |
| effects of citrate on the composition and metabolism of lactobacillus casei. | lactobacillus casei atcc 393 converted small amounts of citrate to diacetyl, other volatile compounds, and lipids. citrate was accumulated passively by the organism. the presence of citrate in the growth medium decreased the uptake of acetate and its conversion to cellular lipids. cells grown in citrate media contained more protein per cell than did controls. this increased protein content was reflected mainly in the soluble fraction when cells were subjected to sonic lysis. soluble fractions fr ... | 1971 | 4327613 |
