“…These enzymes have the ability to support transcription and translation at low temperatures (Goodchild et al, 2004). Psychrophilic enzymes isolated from psychrophilic yeasts exhibit high activity at low and moderate temperatures and thus offer potential economic benefits (Allen et al, 2001). Kourkoutas et al, (2002) reported that psychrophilic yeast can be used in low temperature fermentation.…”

More than 70% of earth's surface is covered by cold ecosystems and these ecosystems have been colonized by a class of extremophilic microorganisms called as psychrophiles. Thus psychrophiles are true extremophiles that has the ability to live in extremely low temperature conditions. Psychrophilic yeasts are important due to their physiological adaptation at low temperature and they have potential application in biotechnology. Psychrophilic yeast produces cold-active enzymes having numerous applications in textile, medical and pharmaceuticals, fine chemical synthesis, food industry, domestic and environmental applications. Psychrophilic enzymes from yeast have attracted attention of researchers to explore the new application of these enzymes because of their high activity at low and moderate temperatures. The present review describes various immune biotechnological applications of different cold-active enzymes produced by psychrophilic yeast in different industries.

“…As with biological potential, the high activity of psychrophilic enzymes offers economic benefits (Allen et al, 2001;Cavicchioli et al, 2002;Gerday et al, 2000;Margesin et al, 2003b;Margesin & Schinner, 1999;Russell, 1998). The goal of energy saving in large-scale processes in industrial fields and waste treatment, for instance, protease enzymes have been used for leather treatment and are carried out by cold-active enzymes instead of tap water at 37.…”

Well-adapted bacteria under wide extreme conditions of acidic/alkaline pH and hot/cold temperatures play a significant role in degradation efficiency and in eliminating the cost of waste treatment processes in large areas. Extremozymes isolated by these organisms are resistant to extraordinary properties of salt allowance, cold adaptivity, and thermostability. In this study, we aimed to assess the isolation of protease-, amylase-, cellulase-, and lignin peroxidase-producing bacteria using a wide range of physical parameters to select suitable isolates and investigate their functions and enzyme activities. The bacterial strain FW2 was isolated from food waste and screened the growth and the degradation of organic compounds under fluctuating temperatures, different pH values, and high salinity concentrations. This strain was able to degrade organic compounds at temperatures from –6℃ to 75°C (weak at 80°C) under a wide pH range of 4.5–12, and in a sodium chloride (NaCl) concentration of 0–35%. Maximum enzyme production was obtained at 1200 U/mL for protease, 2400 U mL-1 for amylase, 920 U/mL for CMCase, 1300 U/mL for Avicelase, and 0.165 U/mL for Lignin peroxidase at pH 7–7.5, 40–45°C, and 0–10% NaCl. With these valuable characteristics, strain FW2 may be a potential contributor to waste degradation under fluctuating environmental conditions.
