1. Candida tropicalis sp. Nov., a novel, zinc-enriched yeast species found in China
Abstract Zinc is one of the most important trace elements and deficiency can lead to significant clinical complications. Microbial transformation is one of the most important methods used to supplement organic zinc and there may be some naturally occurring microorganisms that have both higher zinc tolerances and transformation capabilities. In this study, mi

2. Molecular characterization of yeasts isolated from traditional Turkish cheeses
Abstract Thirty-two yeast strains were identified by means of molecular methods isolated from traditional Turkish cheeses (Tulum, Kashkaval, Mihalic, Orgu, White, Sepet, and Goat). Debaryomyces hansenii and Torulaspora delbrueckii were found as predominant species in cheese samples. Other species which were identified were Kluyveromyces lactis, Candida parap

3. Two Years Monitoring of Ethyl Carbamate in Sugar Cane Spirit from Brazilian Distilleries
This paper describes the monitoring of ethyl carbamate concentration in sugar cane spirit from industrial distilleries in Brazil. In total, 18 distilleries from Minas Gerais and São Paulo states were evaluated, with, a total of 336 samples from August 2017 to August 2019. The ethyl carbamate was analyzed using a previously validated mass spectrometric metho

4. Thermotolerance of Histoplasma capsulatum at 40 °C predominates among clinical isolates from different Latin American regions
ABSTRACT The yeast phase of 22 Histoplasma capsulatum clinical isolates from Mexico, Argentina, Colombia, and Guatemala and three reference strains, one from Panama and two from the United States of America (USA), were screened for thermosensitivity characteristics using different analyses. Growth curves at 0, 3, 6, 12, 24, and 30 h of incubation at 37 and 4

5. Torulaspora globosa: rhizosphere yeast promoting lettuce growth on seedlings and under field conditions
RESUMO Micro-organismos promotores de crescimento vegetal (MPCV) auxiliam as plantas pela produção de fitormônios, disponibilização de nutrientes e manutenção da sanidade vegetal. Dentre os MPCV, as leveduras apresentam grande potencial ainda inexplorado. O objetivo deste trabalho foi avaliar a inoculação da levedura rizosférica Torulaspora globos

6. A NOVEL Scytalidium SPECIES: UNDERSTAND THE CELLULOLYTIC SYSTEM FOR BIOMASS SACCHARIFICATION
ABSTRACT In order to overcome the bottlenecks related to lignocellulosic-derived sugars, the search for more efficient enzymatic cocktails, containing a broad-spectrum of specific activities, relies on an important feature. This paper describes new enzyme activities derived from the novel strain of the Scytalidium genus isolated from the Amazonas rainforest.

7. VALORIZATION OF SOLID WASTES FROM THE BREWERY AND BIODIESEL INDUSTRIES FOR THE BIOPRODUCTION OF NATURAL DYES
This study aims to assess a new approach for concomitant valorization of two industrial wastes - raw glycerin and spent brewer’s yeast - for the bioproduction of valuable carotenoids. Microbial pigments have numerous applications in the food and cosmetic industries. First, four cultures of yeasts were screened using pure glycerol and either (NH4)2SO4 or ur

8. Characterization and comparison of yeasts from different sources for some probiotic properties and exopolysaccharide production
Abstract A total of 134 strains of yeasts isolated from fruits and vegetables (certain berry fruits, apples, pomegranates, carrots and grapes), free-range chicken feces and dairy products, and from 10 commercial yeast preparations were identified and subjected to analyses to determine their in vitro probiotic properties. Based on 26S rRNA sequence analysis a

9. Enhanced Production Of Streptokinase By Chemical Mutagenesis Of Streptococcus agalactiae EBL-20
Abstract Streptokinase (SK) is an enzyme that is used for the treatment of cardiovascular diseases. The current study focused on the enhanced production of SK by inducing mutation in Streptococcus agalactiae EBL-20 and optimization of medium components and culture conditions for the maximum growth of mutant derived strain. S. agalactiae EBL-32 was selected a

10. Cassava Pulp Enzymatic Hydrolysate as a Promising Feedstock for Ethanol Production
ABSTRACT The aim of this study was to produce bioethanol from enzymatic hydrolysates of cassava pulp, a by-product of cassava flour manufacturing, using an alcohol-tolerant Saccharomyces cerevisiae strain. First, the best operational condition of the starch hydrolysis process was determined through a complete factorial design (24), with triplicates at the ce

11. Analysis of radioprotection and antimutagenic effects of Ilex paraguariensis infusion and its component rutin
DNA repair pathways, cell cycle checkpoints, and redox protection systems are essential factors for securing genomic stability. The aim of the present study was to analyze the effect of Ilex paraguariensis (Ip) infusion and one of its polyphenolic components rutin on cellular and molecular damage induced by ionizing radiation. Ip is a beverage drank by most

12. The Mutagenesis of Lactobacillus Thermophilus for Enhanced L-(+)-Lactic Acid Accumulation Induced by Heavy Ion Irradiation
ABSTRACT Screening promising L. thermophiles with high productivity, high efficiency and strong adaptability are very important in lactic acid industry. For this purpose, 80MeV/u carbon ions were applied to irradiate L. thermophiles. After high-throughput screening, a mutant, named SRZ50, was obtained. Different carbon sources or nitrogen sources were provid
