title: Identity and lipase activity of an isolate of Thermoactinomyces vulgaris.
abstract: An actinomycete with thermophilic nature and strong lipolytic activity was isolated by enrichment from an Egyptian soil. It proved to be Thermoactinomyces vulgaris. Variabilities justifying Adansonian systematics were reported and discussed. The potential relation of an occasional drop in successfully resumed activity to an auto-inhibition phenomenon has been notified. Optimum conditions for the activity of the extracellular lipase(s), including stability, suggest the practical importance of the enzyme(s) in the growth filtrates.
