The poly-l-lactic acid (PLLA) has been used for almost 20 years; this bio-stimulant substance is used for improving the lost volume of the face and many other parts of the body, not just like a filler but like one of the most potent stimulants of neocollagenesis. The poly-l-lactic acid (PLLA) has been used for improving the lost volume of many parts of

The poly-L-lactic acid (PLLA) injection technique stimulates neocollagenesis and provides a natural look. In recent years there has been a growing interest for using this in other body areas such as the neck, chest, back of hands, lower breast region, thoraco-axillary fold, buttocks, arms and medial thighs.

Microbial degradation of poly-(l-lactic acid) oligomers
Polymer Degradation and Stability, 1998Biotic and abiotic degradation of poly-(l-lactic acid) (PLLA) oligomers of molecular weight (MW) 260–2880 g mol−1 has been studied in an aquatic aerobic headspace biodegradation test for six months. Water soluble/dispersable PLLA oligomers (MW 260–550 g mol−1) biodegraded at 25 °C and at 58 °C. Larger, crystalline and hydrophobic oligomers (MW 550–2880

l-lactic acid production by Bacillus subtilis MUR1
Bioresource Technology, 2012Bacillus subtilis MUR1 is a novel lactic acid (LA) producing strain that has the potential for industrial production of LA due to its high productivity of LA, high yield of substrate conversion, and high final concentration of LA produced. B. subtilis MUR1 can produce 99.3 and 183.2g/l of L-LA in 12 and 52 h respectively with a 98.5% substrate ...

Dermatologic Surgery, 2009
Injectable poly-l-lactic acid (PLLA) has been used to correct age- or disease-related facial volume deficits.This single-center, retrospective survey evaluated PLLA for cosmetic use.A questionnaire was mailed to 281 patients treated with PLLA 6 months or more previously. PLLA was reconstituted 4 hours or more before injection with 5 mL of sterile water

Poly-l-Lactic Acid for Neck and Chest Rejuvenation
Dermatologic Surgery, 2009Poly-L-lactic acid (PLLA) has been widely used in the enhancement of facial contours, but its use in nonfacial areas is rarely cited.To demonstrate the efficacy and safety of PLLA for neck and chest rejuvenation.Thirty-six patients with different degrees of cutaneous flaccidity, atrophy, and wrinkles in the neck and chest were treated with PLLA.

Biotechnological production of lactic acid (LA) is based on the so-called first generation feedstocks, meaning sugars derived from food and feed crops such as corn, sugarcane and cassava. The aim of this study was to exploit the potential of a second generation resource: Common reed (Phragmites australis) is a powerfully reproducing sweet grass which ...

D- and L-Lactic acid oxidase of Escherichia coli
Biochimica et Biophysica Acta, 1959Abstract A particulate enzyme complex from Escherichia coli catalyzing the oxidation of lactate to pyruvate has been studied. Enzyme preparations obtained from celss of E. coli, grown in synthetic medium containing DL -lactate, oxidized both isomers of lactate.
