Two Polyketides from a Co-culture of Two Marine-derived Fungal Strains
(Natural Product Communications, 2013-06-01) [Artigo]
Co-cultivation of the fungal strains Penicillium sp. Ma(M3)V and Trichoderma sp. Gc(M2)1 in malt 2% medium led to the production of two novel, unusual polyketides, (Z)-2-ethylhex-2-enedioic acid and (E)-4-oxo-2-propylide ...
Cellulolytic activity of wild type and mutant Trichoderma pseudokoningii
(Journal of Basic Microbiology, 1999-12-01) [Artigo]
Strains of Trichoderma pseudokoningii are promising objects for genetic studies and cellulase production. Auxotrophic mutants with deficiencies in the biosynthesis of aminoacids, nucleotides and vitamins (up to five markers) ...

Response surface optimization of D(-)-lactic acid production by Lactobacillus SMI8 using corn steep liquor and yeast autolysate as an alternative nitrogen source
(African Journal of Biotechnology, 2009-11-02) [Artigo]
The production of D(-) lactic acid from Lactobacillus LMI8 sp. was studied, using 2 low-cost nitrogen sources: corn steep liquor (CSL) and yeast autolysate (YA). A central composite design was used to determine maximal ...
Aerobic biodegradation of butanol and diesel oil blends
(African Journal of Biotechnology, 2010-10-18) [Artigo]
This work aimed to evaluate the aerobic biodegradation of butanol/diesel oil blends (5, 10, 15, 20%, v/v) in comparison to the biodiesel/diesel oil blend (20%, v/v). Respirometric experiments simulating the contamination ...
Biodegradation of biodiesel/diesel blends by Candida viswanathii
(African Journal of Biotechnology, 2009-06-17) [Artigo]
This work is aimed to assess the aerobic biodegradation of biodiesel/diesel blends (0, 2, 5, 20 and 100%, v/v) by Candida viswanathii. The biodegradation potential of the inoculum was assessed with the redox indicator ...
Influence of nitrogen source and sucrose concentration on inulinase production by Kluyveromyces marxianus in fed-batch fermentation
(African Journal of Biotechnology, 2011-09-26) [Artigo]
This work studied the influence of nitrogen source and sucrose concentration in the feeding medium for biomass and inulinase production by Kluyveromyces marxianus var. bulgaricus. The results show that the best nitrogen ...
Disseminated Amphotericin-Resistant Fusariosis in Acute Leukemia Patients: Report of Two Cases
(Mycopathologia, 2013-01-01) [Artigo]
Disseminated fusariosis has emerged as a significant, usually fatal infection in immunocompromised hosts despite antifungal treatment. We describe here two patients with acute leukemia who developed disseminated ...
Production and partial characterization of keratinase produced by a microorganism isolated from poultry processing plant wastewater
(African Journal of Biotechnology, 2008-02-05) [Artigo]
A Streptomyces was isolated from poultry plant wastewater, showed high keratinolytic activity when cultured on feather meal medium. Optimum keratinolytic activity was observed at 40°C and pH 8.0. The enzyme also showed to ...
Intraspecific variation and emendation of Hannaella kunmingensis
(Mycological Progress, 2013-01-01) [Artigo]
In order to investigate the intraspecific variability in Hannaella kunmingensis, 11 isolates, including the type strain, were analyzed for their morphological and biochemical traits. The combined internal transcribed spacer ...
