Fruits release specific volatiles as vapors during spoilage that can provide information about the spoilage stages of fruits. We used long optical path Fourier Transform Infrared Spectroscopy (FTIR) and sensor arrays comprising carbon dioxide and ethanol sensors to study the grape spoilage process synchronously. The results revealed that specific volatiles, such as carbon dioxide, ethanol and e...

The rate of spoilage of chicken tissues, the development of spoilage bacteria, and the utilization of amino acids by spoilage bacteria as a function of temperature were more accurately described by the general spoilage curve of Olley and Ratkowsky (Food Technol. Aust. 25:66-73, 1973; Food Technol. N.Z. 8:13-17, 1973) than by the linear equation of Spencer and Baines (Food Technol. [Chicago] 18:...

This study aimed to investigate the viable but nonculturable (VBNC) state and genomic features of a beer-spoilage strain, Lactobacillus caseiBM-LC14617. Induction on the VBNC state of L. casei strain BM-LC14617 was conducted by both low-temperature storage and continuous passage in beer, and formation of VBNC state was detected after 196 ± 3.3 days and 32 ± 1.6 subcultures, respectively. Resusc...

UNLABELLED Commercial cucumber fermentations are typically carried out in 40000 L fermentation tanks. A secondary fermentation can occur after sugars are consumed that results in the formation of acetic, propionic, and butyric acids, concomitantly with the loss of lactic acid and an increase in pH. Spoilage fermentations can result in significant economic loss for industrial producers. The micr...

We have isolated a hop-sensitive variant of the beer spoilage bacterium Lactobacillus lindneri DSM 20692. The variant lost a plasmid carrying two contiguous open reading frames (ORF s) designated horB(L) and horC(L) that encode a putative regulator and multidrug transporter presumably belonging to the resistance-nodulation-cell division superfamily. The loss of hop resistance ability occurred w...

UNLABELLED Cucumbers are preserved commercially by natural fermentations in 5% to 8% sodium chloride (NaCl) brines. Occasionally, fermented cucumbers spoil after the primary fermentation is complete. This spoilage has been characterized by decreases in lactic acid and a rise in brine pH caused by microbial instability. Objectives of this study were to determine the combined effects of NaCl and ...

The spoilage potential of several Psychrobacter and Pseudoalteromonas species (Psychrobacter cibarius, Psychrobacter maritimus, Pseudoalteromonas elyakovii, Pseudoalteromonas paragorgicola and Pseudoalteromonas nigrifaciens) was determined and quantified based on the presence of volatile organic compounds (VOCs). Psychrobacter and Pseudoalteromonas species dominate the microbiota of cooked brow...

Most food products are highly perishable as they constitute a rich nutrient source for microbial development. Seafood is one of the most highly perishable food products due to the chemical effects of atmospheric oxygen and the growth of spoilage microorganisms. Therefore, the spoilage of food depends up on the physiological state of spoilers and on their ability to resist the processing/storage...

Sterile press juice as a suitable experimental medium. Appl. Microbiol. 11:458-462. 1963.-A sterile raw fish muscle press juice, diluted 1:4 with saline, has been prepared. This dilution greatly facilitated Seitz filtration and affected the spoilage ...
