Effect of media supplements and culture conditions on inulinase production by an actinomycete strain

Production, Purification and Characterization of Inulinase from a Newly Isolated <i>Streptomyces</i> sp. CP01

“…This level was comparable to those reported from the other Streptomyces which were grown under their optimal conditions including Streptomyces sp. GNDU1 (0.55 U/ml) [13] and Streptomyces sp. isolated from chicory root (0.52 U/ml) [12].…”

“…and Kluyveromyces marxianus ATCC 52466 [6][7][8][9][10][11]. However, there was only few reports on inulinases from Streptomyces [12,13]. It is well known that several Streptomyces species produce a great variety of useful bioactive metabolites, including antibiotics, anticancer agents, insecticides, enzyme inhibitors and industrial important enzymes.…”

Effects of culture conditions on the production of inulinase by Kluyveromyces marxianus

“…Similar to the inulinase of Aspergillus niger A 42 (Öngen-Baysal et al, 1994), A. fumigatus (Kauer et al, 1999) and Streptomyces sp. (Gill et al, 2003), K. marxianus var. bulgaricus inulinase also appeared to be regulated by a double mechanism: increase by the substrate and repression by the product (glucose and fructose), as the activity decreased with sucrose concentrations above 10 g L-1, probably suppressed by reducing sugars.…”

Medium optimization for the production of avermectin B1a by Streptomyces avermitilis 14-12A using response surface methodology

“…In previous experiments, it was found that yeast extract is the preferred nitrogen source of Streptomyces strains (Gill et al, 2003;Lazim et al, 2009;Tuncer et al, 2004). However, every coin has two sides; it is also true for yeast extract in some Streptomyces strains (Niladevi et al, 2009).…”
