Important Functions of NP-LP Molecules
Many reports suggest that LPs produced from Bacillus spp. in nano-form are useful
for controlling mould, fungal and bacterial pathogens (Ongena and Jacques 2007;
Valodkar et al. 2011). Metal NPs have good antimicrobial activities, and NP-LP-
based antimicrobial formulations could be an effective fungicidal as well as bacteri-
cidal agents (Rai et al. 2009). Surfactin-functionalized poly methyl methacrylate
(PMMA) showed antimicrobial effect against Escherichia coli (300 μg/mL) of the
NP-LP molecules. Also, the low haemolytic activity exhibited by these NPs reduces
the amount of increased toxicity. A new surfactin-SMEDDS nano-formulation has
been developed, although more confirmation was needed for their anticancerous
activity (Hore 2019). The combination of surfactin along with nano-emulsion could
act as a great drug delivery agent and which could be successfully used as in
anticancer treatment (Table 26.2 and Fig. 26.2). Surfactin-based NPs also have
uses in overcoming multidrug resistance in cancerous cells, for example, surfactin-
loaded NPs loaded with doxorubicin. Doxorubicin has the purpose of stopping the
growth of the cancerous cells. It is type of chemotherapy used for the treatment
purpose of different type of cancer. β-Casein balanced out LP lyotropic liquid crystal
NPs has been utilized, i.e. these are the NPs of lipopeptides and the mixture of
doxorubicin which was an anthracycline, and therefore these lyotropic liquid NPs
Table 26.2 Describes some functions and applications of lipopeptides in different inorganic and
organic nano-formulations
