The objective of this study was to identify Acinetobacter in a traditional cheese from west Azarbaijan, Iran, and to study the lipolytic and proteolytic activities of these bacteria in ripening of white brine cheese. Acinetobacter is a gram negative bacteria which can be found in different sources as dairy products. Lypolysis and proteolysis characteristic of this bacteria and...

It has been observed that nucleic acids, nucleotides, and nucleosides inhibit the lipolytic action of epinephrine on adipose tissue, whereas purine and pyrimidine bases increase it (1). Further studies, described in the present report, have shown this interaction to be quite specific for lipolysis (uptake and esterification of fatty acids being unaffected), but not limited to epinephrine (other...

Lipases are enzymes used in various industrial sectors such as food, pharmaceutical and chemical synthesis industries. The selection of microorganisms isolated from soil or wastewater is an alternative to the discovery of new species with high enzymes productivity and with different catalytic activities. In this study, the selection of lipolytic fungi was carried out by submerged fermentation. ...

Screening of lipolytic strains using Rhodamine-B/olive oil plate technique allowed the selection of Aspergillus niger MYA 135. Lipase production in submerged culture containing 2 % olive oil was enhanced by more than 50 % compared to basal cultural conditions. Optimal catalytic conditions for olive oil-induced lipase were pH=6.5 and 30–35 °C. These values were shifted to the acid region (4.0–6....

Catecholamine-induced lipolysis in isolated human adipocytes during the first year of life was investigated. During this period fat cell size increased markedly. Basal and catecholamine-induced glycerol release were positively correlated with age when lipolysis was expressed per cell. However, when lipolysis was expressed per unit of cell surface area (micrometer squared), this correlation was ...

Proteolytic and/or lipolytic lactic acid bacteria (LAB) were isolated from visceral wastes of different fresh water fishes. LAB count was found to be highest in case of visceral wastes of Mrigal (5.88 log cfu/g) and lowest in that of tilapia (4.22 log cfu/g). Morphological, biochemical and molecular characterization of the selected LAB isolates were carried out. Two isolates FJ1 (E. faecalis NC...

Environmental DNA libraries prepared from three different soil samples were screened for genes conferring lipolytic activity on Escherichia coli clones. Screening on triolein agar revealed 1 positive clone out of 730,000 clones, and screening on tributyrin agar revealed 3 positive clones out of 286,000 E. coli clones. Substrate specificity analysis revealed that one recombinant strain harbored ...

The crude enzyme fraction was isolated from the fresh unripe fruits of Momordica charantia Linn and screened for its amylolytic and lipolytic activity according to standard literatures. The results indicated that the crude enzyme fraction is having effective amylolytic and lipolytic activities. These enzymatic activitieis of the extract substantiate the validity of claims made in traditional sy...

Obesity often leads to increased systemic inflammation which is now thought to play a causative role in the development of atherosclerotic disease and insulin resistance. This inflammatory response originates within large adipose tissue depots and is initiated by classically activated macrophages that infiltrate the tissue from the circulation. The large number of macrophages residing in obese ...

Bacterial lipolytic enzymes were originally classified into eight different families defined by Arpigny and Jaeger (families I-VIII). Recently, the discovery of new lipolytic enzymes allowed for extending the original classification to fourteen families (I-XIV). We previously reported that G. thermodenitrificans EstGtA2 (access no. AEN92268) belonged to a novel group of bacterial lipolytic enzy...
