“…Similarly, the growth of gram-positive bacteria (Bacillus megaterium and Bacillus subtilis) was restrained by MEL-A and MEL-B reported by Recke et al, and they also found MELs showed moderate antifungal effects on Candida magnoliae [73]. Besides, Okuhira et al compared the antimicrobial effects of MEL against two types of bacteria and summarized MEL selectively inhibited the proliferation of most gram-positive bacteria below the concentration of 50 µg/mL, but not gram-negative bacteria [74]. Furthermore, Nashida et al synthesized 20 congeners of MELs through a chemical process and compared their inhibition on microbes, and the results illustrated not only the length of the alkyl chains but also the pattern of Ac groups on the mannose moiety were important factors for antibacterial activity [75].…”

Glycolipid biosurfactants are natural amphiphiles and have gained particular interest recently in their biodegradability, diversity, and bioactivity. Microbial infection has caused severe morbidity and mortality and threatened public health security worldwide. Glycolipids have played an important role in combating many diseases as therapeutic agents depending on the self-assembly property, the anticancer and anti-inflammatory properties, and the antimicrobial properties, including antibacterial, antifungal, and antiviral effects. Besides, their role has been highlighted as scavengers in impeding the biofilm formation and rupturing mature biofilm, indicating their utility as suitable anti-adhesive coating agents for medical insertional materials leading to a reduction in vast hospital infections. Notably, glycolipids have been widely applied to the synthesis of novel antimicrobial materials due to their excellent amphipathicity, such as nanoparticles and liposomes. Accordingly, this review will provide various antimicrobial applications of glycolipids as functional ingredients in medical therapy.

“…Surfactant not only influence the rumen metabolites but have impact on rumen microflora. For example, a recent study has demonstrated that the biosurfactant manosylerythritol lipid decrease the numbers of most of ruminal gram-positive bacteria, reduce methane production, and increase the ratio of propionate to acetate [ 10 ]. Our previous studies have extensively explored the anionic surfactant docusate (DOC or aerosol OT), an anionic surfactant, led to a in the diet decreased protozoan count, increased total amount of bacteria in rumen [ 11 ], increased activities of fiber-degrading enzymes in the rumen [ 12 ], increased nutrient absorption from the small intestine [ 9 ] and nitrogen retention in sheep [ 13 , 14 ], and improved the slaughter performance of lambs [ 7 ].…”

This study was conducted to evaluate the effect of polyacrylamide (PAM) supplementation on the intake, digestion, weight gain, metabolism and growth of lambs. A total of ten 30 days old male small-tailed Han lambs with a body weight of 7.7±0.5 kg were divided into two equal groups (n = 5 each) and fed a basal diet or diet supplemented with 2.0 g of PAM per kg diet. The duration of the experiment was 210 days and experimental diets were fed ad libitum throughout the experimental period. Voluntary feed intake (VFI) was measured on daily basis, while body weight was measured on every ten days of the experiment.Two digestive and metabolic trials were conducted at the lamb’s age of 95 to 103 days (Trial 1) and at the age of 210 to 218 days (Trial 2). At the end of experiment, all lambs were slaughtered to determine carcass characteristics. Results of the current study showed that supplementation of PAM in the diet of lambs increased the VFI and daily body gain by 14.4% (P < 0.05) and 15.2% (P < 0.01), respectively. In Trial 1, PAM supplementation in the diet increased the digestibility of dry matter (DM), organic matter (OM), crude protein (CP), cellulose, energy, and nitrogen retention by 7.9%, 5.4%, 6.4%, 9.6%, 4.3% and 30.3% (P < 0.01), respectively, and in Trial 2, PAM supplementation in the diet increased the digestibility of DM, OM, CP, cellulose, energy, and nitrogen retention by 9.3%, 7.9%, 7.7%, 11.6%, 6.9% and 38.5% (P < 0.01), respectively. Results of carcass parameter explored that supplementation of PAM in the diet increased the carcass, net meat and lean meat weights by 24.5%, 25.5%, and 30.6% (P < 0.01), respectively, however, PAM supplementation in the diet did not influence the contents of DM, OM, or CP in fresh liver, leg muscle, and rumen tissue; in addition, the CP contents in the Longissimus dorsi muscle was decreased by the supplementation of PAM in the diet. In summary, supplementation of 2.0 g of PAM per kg diet increased the VFI, nutrient digestibility, nitrogen retention, and carcass yield of lambs.
