Technical Reports: Langley Aerospace Research Summer Scholars
The Langley Aerospace Research Summer Scholars (LARSS) Program was established by Dr. Samuel E. Massenberg in 1986. The program has increased from 20 participants in 1986 to 114 participants in 1995. The program is LaRC-unique and is administered by Hampton University. The program was established for the benefit of undergraduate juniors and seniors and first-year graduate students who are pursuing degrees in aeronautical engineering, mechanical engineering, electrical engineering, material science, computer science, atmospheric science, astrophysics, physics, and chemistry. Two primary elements of the LARSS Program are: (1) a research project to be completed by each participant under the supervision of a researcher who will assume the role of a mentor for the summer, and (2) technical lectures by prominent engineers and scientists. Additional elements of this program include tours of LARC wind tunnels, computational facilities, and laboratories. Library and computer facilities will be available for use by the participants

Yeasts from Canastra cheese production process: Isolation and evaluation of their potential for cheese whey fermentation
Canastra cheese is a cheese with geographical indication recognized by the Brazilian National Institute of Industrial
Protection under number IG201002. It is produced in seven municipalities in the state of Minas Gerais in a
region called Serra da Canastra. In thiswork, samples of milk, “pingo” (natural starter),whey and Canastra cheese
were collected on a farm inMedeiros-MG/Brazil to evaluate the yeast microbiota and select yeasts for whey fermentation
to produce ethanol and volatile aromatic compounds of relevance in the production of cheese. Thirtynine
isolates capable of fermenting lactose in a synthetic medium were identified by MALDI-TOF as
Kluyveromyces lactis (29), Torulaspora delbrueckii (7) and Candida intermedia (3). Eleven isolates of K. lactis and
three of T. delbrueckii efficiently fermented lactose until 4th day, and due to this reason were selected for cheese
whey fermentation with Brix 12, 14 and 18. Generally, the isolates T. delbrueckii B14, B35, and B20 and K. lactis
B10 were the most effective regardless of the initial Brix value. The identification of these four isolates by
MALDI TOF was confirmed by sequencing of the ITS region. In the fermentation of cheese whey 14 Brix, T.
delbrueckii B14 and B35, respectively yielded 24.06 g/L and 16.45 g/L of ethanol, while K. lactis B10 was more efficient
in the consumption of lactose. In sequential culture with K. lactis B10 inoculated 48 h after T. delbrueckii
B14, 97.82% of the total sugars were consumed resulting in the production of 19.81 g/L ethanol and 39 aromatic
volatile compounds. The most abundant compounds were 3-methyl-1-butanol, octanoic acid and ethyl
decanoate, which are reported as important for the aroma and flavor of cheeses. Based in our results, B10 isolate
inoculated 48 h after B14 isolate is a promising yeast inoculum to be used for fermentation of dairy substrates.The authors thank CNPq (Conselho Nacional de Desenvolvimento Científico e Tecnológico do Brasil), CAPES (Coordenação de Aperfeiçoamento de Pessoal de Nível Superior) and FAPEMIG (Fundação de Amparo à Pesquisa do Estado de Minas Gerais) for financial support.
