Saccharomycopsis lipolytica

One of the first reports on yeast-mediated color removal by a putative process of biosorption of azo dyes by yeast (Rhodotorula sp.) biomass belongs to [31]. Yeast species such as Kluveromyces marxianus removed the diazo dye remazol black B [10], Candida catenulata and Candida kefyr removed more than 90% of amaranth by biosorption [6]. Biosorption uptake of the textile azo dyes remazol blue, reactive black, and reactive red by S. cerevisiae and C. tropicalis varied according to the selected dye, dye concentration, and exposure time [5, 7]. In a recent screening work carried out by [32], from the 44 yeast strains tested for their decolorization ability, 12 of them removed the dye Reactive Brilliant Red K-2BP by biosorption, among them the following were identified S. cerevisiae, Saccharomyces uvarum, Torulopsis Candida, and Saccharomycopsis lipolytica. 

When we started to look for the mode of action of different EBI s, we decided to use several pathogens as test organisms. These were Pyricularia oryzae, Botrytis cinerea, Cercospora musae, Fusarium nivale, and Drechslera teres. To get rapid information about the possible antimycotic efficacy of a test compound, we also used a non-pathogenic yeast, Saccharomycopsis lipolytica. 

Citric acid Various sugars Aspergillus niger Saccharomycopsis lipolytica... 

Citric acid can be produced in high productivity and high yield by fermentation of simple sugars mainly by the mycelial fungus, Aspergillus niger, although some processes use the yeast Yarrowia lipolytica (Candida lipolytica or Saccharomycopsis lipolytica) with n-alkane as the substrate. 

The uptake kinetics of C-labelled triadimenol, shown in figure 6 were examined in both the susceptible and triadimenol-resistant strains of the yeast Saccharomycopsis lipolytica. To minimize the effect of unspecific absorption on the cell surface the incubated cells were separated by suction filtration and washed twice with unlabelled triadimenol. The passive uptake curve shows the typical characteristics of saturation by diffusion, equilibrium being reached after about 20 minutes. There are no real differences between the susceptible and resistant isolates, and no indication of transport mutation or induction of efflux transport can be derived from these data. 

To summarise, the typical resistance mechanisms one would expect, namely transport mutation, enhanced detoxification and target mutation, have been investigated in the case of Saccharomycopsis lipolytica without positive results. 

Trichosporon pullulans probably includes Endomycopsis vernalis which is no longer a recognized name. Yarrowia lipolytica is variously referred to as Candida lipolytica and Saccharomycopsis lipolytica amongst other names. Only a few strains may be oleaginous.
