Microbial metabolites produced during fermentation migrate into the coffee and can influence the decrease in seed viability and coffee quality. This study evaluated the effects of physiological changes in seed viability on the sensory quality of the beverage using starter cultures through self-induced anaerobic fermentation (SIAF) in Coffea arabica L. for natural and pulped coffee. The yeasts were monitored by real-time polymerase chain reaction (qPCR). High-performance liquid chromatography (HPLC) detected citric, malic, and succinic acids in all fermented coffees. Furthermore, lactic acid was mainly identified in those coffees processed by the SIAF method. Volatile compounds (40) were detected by gas chromatography-mass spectrometry (GC-MS). Alterations in physiological quality were identified, with decreased embryonic viability and cell membrane damage by tetrazolium and electrical conductivity tests. All fermented coffees obtained scores above 80 points. The Torulospora delbrueckii yeast got the best score (86.50) in pulped coffee, and the Candida parapsilosis yeast received the highest score (85.90) in the natural coffee using the SIAF method. The coffees were characterized by aromas and flavors of citrus, caramel, honey, chocolate, and chestnut. The coffee fermentation process with yeast inoculation affected the coffee bean viability but not the beverage's sensory quality, indicating that the use of yeast starters by SIAF favors the production of specialty coffees with differentiated sensory characteristics.

RESUMO- O trabalho foi conduzido no Centro Nacional de Pesquisa de Gado de Leite (CNPGL) da EMBRAPA, numa área de topografia acidentada e de baixa fertilidade natural. Avaliou-se agronomicamente 25 gramíneas forrageiras sob condição de pastejo em um delineamento de blocos ao acaso, repetidos três vezes. As espécies B. decumbens (BRA 000060 e BRA 000086), B. brizantha e S. sphacelata apresentaram altas taxas de crescimento como também proporcionaram boa cobertura do solo. As espécies P. maximum cv. Makueni e A. gayanus cv. Planaltina, apesar de se situarem entre as gramíneas mais produtivas, não foram eficientes na cobertura do solo. A aceitabilidade da forragem pelos animais foi alta para A. gayanus, B. ruziziensis, P. maximum cv.Makueni e S. sphacelata; baixa para B. humidicola e B. dictyoneura; e intermediária para as demais espécies. O teor de proteína bruta (PB) foi relativamente alto para a maioria das gramíneas, variando entre espécies e épocas do ano. ABSTRACT- An experiment designed to evaluae agronomically 25 forage grasses under grazing was conducted at the Centro Nacional de Pesquisa de Gado de Leite (CNPGL-EMBRAPA). The sou was a 10w fertility oxisol, in a hilly country characteristic of a large area of South-east Brazil). The species Si'achiaria decumbens, 8. brizantha and Setaria sphacelata presentert high growth rates as velI as good soil cover. The species Panicum maximum cv. Makueni and Andropogon gayanus cv. Panaltina though included amongst the highest yielding grasses, faiied to offer a good soil cover. Forage acceptability by grazing animais was high for A. gayanus, P. maximum cv. Makueni and S. sphacelata, Iow for 8. humidicola and 8. dictyoneura and intermediate for the other species. Crude protein content in the drymatter was eather high in the majority of the grasses, but varied among species and seasons.
