Notes:
Cheddar cheese was manufactured by inoculation with and without cultures of homofermentative Lactobacillus strains (L. casei-subsp-casei, L. casei-subsp-pseudoptantarum, L. plantarum). Growth rate of microflora, the incidence of heterofermentative lactobacilli and the rate of proteolysis were then studied during aging. The total number of psychotrophs, mesophiles and lactic streptococci reached a maximum at 5 months but maximum numbers attained were dependent upon the curing temperature (7°C or 15°C). The acceleration of cheese ripening by Lactobacillus cultures was accompanied by a greater degree of protein hydrolysis which was detectable after 8 months aging as soluble nitrogen in TCA extracts (360 mg/100g at 15°C and 240 mg at 7°C, versus 170 mg and 75 mg, respectively, for the controls).
