“…Chronic hyperglycemia promotes the generation of free radicals, which can lead to lipid peroxidation, non-enzymatic protein glycation, structural and functional changes in the basement membrane and collagen, and enzyme inactivation, all of which contribute to complications of diabetes [ 46 , 47 ]. Glycemic management is one of the most important aims for diabetes treatment since oxidative stress-induced hyperglycemia plays such a big role in the progression of diabetes.…”

Natural products in the form of functional foods have become increasingly popular due to their protective effects against life-threatening diseases, low risk of adverse effects, affordability, and accessibility. Plant components such as phytosterol, in particular, have drawn a lot of press recently due to a link between their consumption and a modest incidence of global problems, such as Type 2 Diabetes mellitus (T2DM), cancer, and cardiovascular disease. In the management of diet-related metabolic diseases, such as T2DM and cardiovascular disorders, these plant-based functional foods and nutritional supplements have unquestionably led the market in terms of cost-effectiveness, therapeutic efficacy, and safety. Diabetes mellitus is a metabolic disorder categoriszed by high blood sugar and insulin resistance, which influence major metabolic organs, such as the liver, adipose tissue, and skeletal muscle. These chronic hyperglycemia fallouts result in decreased glucose consumption by body cells, increased fat mobilisation from fat storage cells, and protein depletion in human tissues, keeping the tissues in a state of crisis. In addition, functional foods such as phytosterols improve the body’s healing process from these crises by promoting a proper physiological metabolism and cellular activities. They are plant-derived steroid molecules having structure and function similar to cholesterol, which is found in vegetables, grains, nuts, olive oil, wood pulp, legumes, cereals, and leaves, and are abundant in nature, along with phytosterol derivatives. The most copious phytosterols seen in the human diet are sitosterol, stigmasterol, and campesterol, which can be found in free form, as fatty acid/cinnamic acid esters or as glycosides processed by pancreatic enzymes. Accumulating evidence reveals that phytosterols and diets enriched with them can control glucose and lipid metabolism, as well as insulin resistance. Despite this, few studies on the advantages of sterol control in diabetes care have been published. As a basis, the primary objective of this review is to convey extensive updated information on the possibility of managing diabetes and associated complications with sterol-rich foods in molecular aspects.

“…Biosurfactants are organic, surface-active amphiphilic compounds that contain both hydrophobic and hydrophilic moieties, produced mainly by diferent microorganisms (bacteria, yeast, or fungi) on cell surfaces or can be secreted extracellularly [1,2]. Tey could accumulate between fuid phases and help in reducing the surface and interfacial tensions, which will make them potential candidates for boost oil recovery, biodegradation, and bioremediation [3][4][5][6][7][8].…”

“…With a worldwide preference for renewable products, attention to microbial surfactants has been increased due to their diversity, selectivity, low toxicity, biodegradability, ecological acceptance, efectiveness at extreme pH and temperatures, the possibility to be produced through fermentation, and widespread applicability [4,9,10]. Nowadays, biosurfactants are used in industries such as pharmaceuticals and cosmetics and have emerged as potential agents in food industries and agriculture, possessing several interesting properties of medical importance, bioremediation of petroleum pollutants, management and enhancing crude oil recovery, lubrication, solubilization, wetting, detergency, and recently biosurfactants have been found to disrupt bioflm formation [2][3][4][5][6][7][8][9].…”

Microbial surfactants are widely used in medical, pharmaceutical, agricultural, industrial, food, and cosmetics applications. In the present study, 85 indigenous bacteria were isolated from petroleum-contaminated soils of the Al Dourah refinery, electric power station, and electric generators in Baghdad, Iraq. Twenty nine isolates gave positive results in both blood agar and blue agar medium and were secondarily screened. One isolate was selected as a potent biosurfactant producer and molecularly identified and recorded in the NCBI GenBank nucleotide sequence database as Pseudomonas guguanensis strain Iraqi ZG.K.M. In optimized conditions, this strain can produce about 3.01 g/l of biosurfactant. The product could reduce the surface tension from 72 to 38 ± 0.33 mN/m and have E24% of 52 ± 0.33%. This biosurfactant was preliminarily specified to be a glycolipid and characterized as a rhamnolipid with anionic nature, usually to be a monorhamnolipid as evident from TLC, FTIR, and GC-MS analyses.

Bu çalışmada, çeşitli çevresel örneklerden n-dekan yüzeyine en iyi şekilde adsorbe olan bakterilerin izolasyonu, biyodegredasyon yetenekleri ile çeşitli fizyolojik özelliklerinin belirlenmesi ve yağ/su ara yüzü ile bakteriyel etkileşimlerin incelenmesi amaçlanmıştır. Yöntem: Çalışmanın amacına uygun olarak çevresel örneklerden bakteri izolasyonları yapılmıştır. İzolatlar koloni ve hücre morfolojileri ile Gram reaksiyonları bakımından incelenmiştir. İzolatların yağ/su ara yüzü etkileşimleri ve yağa tutunma durumları hidrokarbona bakteriyel adezyon (HBA) testi ile belirlenmiştir. Ayrıca, izolatların n-dekan giderim yetenekleri kantitatif olarak yağ parçalama oranı (YPO) analizi ile gerçekleştirilmiştir. Bulgular: n-dekan içeren besiyeri kullanılarak n-dekan parçalanması ve yağ/su ara yüzü etkileşimleri ile ilgili yapılan çalışmalardan 12 bakteriyel izolat elde edilmiştir. İzolatların agar petri üzerinde farklı koloni morfolojileri sergiledikleri gözlenmiştir. Hücre boyama sonucu, izolatların çoğunluğunun çubuk morfolojide olduğu ve Gram reaksiyonlarının değişkenlik gösterdiği tespit edilmiştir. Yağ/su ara yüzüne adsorbsiyon analizlerinde, izolatların çoğunun değişen oranlarda (%3-25) yağ/su ara yüzüne tutunduğu tespit edilmiştir. Bunun yanında, bazı izolatların ise hidrofobik özellik sergilemediği saptanmıştır. Çalışmadan elde edilen izolatların %48-97 oranında n-dekan giderimi yapabildikleri tespit edilmiştir. Sonuç: Ön çalışma niteliğinde yapılan yağ/su ara yüzü çalışmalarından elde edilen mevcut verilere göre, bakteriyel hidrofobisite/adsorpsiyon ile biyofilm oluşumu arasında doğrudan bir ilişki kurulamasa da, hidrofobik özellikteki bakterilerin yağ/su ara yüzünde iyi derecede biyofilm yapısı oluşturduğu söylenebilir. Ayrıca, n-dekana iyi adsorbe olan izolatların aynı zamanda yüksek bir n-dekan giderim yeteneğine sahip oldukları gözlenmiştir.
