Retrieval of unintelligible speech is a basic need for speech impaired and is under research for several decades. But retrieval of random words from thoughts needs a substantial and consistent approach. This work focuses on the preliminary steps of retrieving vowels from Electroencephalography EEG signals acquired while speaking and imagining of speaking a consonant—vowel—consonant CVC word. The process, referred to as Speech imagery is imagining of speaking to oneself silently in the mind. Speech imagery is a form of mental imagery. Brain connectivity estimators such as EEG coherence, Partial Directed Coherence, Directed Transfer Function and Transfer Entropy have been used to estimate the concurrency and causal dependence direction and strength between different brain regions.

Lipases are enzymes that catalyze the ester bond hydrolysis in triglycerides with the release of fatty acids, mono- and diglycerides, and glycerol. Many biotechnological processes are expedited at high temperatures and hence much research is dealt with thermostable enzymes.

In addition, they consume less energy since they are active at low temperatures. These cold active lipases have not been commercially exploited so far compared to mesophilic and thermophilc lipases. Kavihha active lipases are distributed in microbes found at low temperatures. Only a few microbes were studied for the production of these enzymes.

These cold-adapted enzymes show increased flexibility of their structures in response to freezing effect of the cold habitats.

This review presents an update on cold-active lipases from microbial sources along with some structural features justifying high enzyme activity at low temperature. In addition, recent achievements on their use in various industries will also be discussed. This is a preview of subscription content, access via your institution.
